Video Transcription

• 00:00:00 Greetings everyone. Today I am going to  show you how to turn these simple blocks  

• 00:00:05 into useful modeled forms. We will build a  recessed platform, an open equipment housing,  

• 00:00:11 and a shaped courier shell. This is lecture 2  of our Blender course. We are continuing from  

• 00:00:18 the station saved in lecture 1. You can find  that starting file, today's companion files,  

• 00:00:24 and the chapters in the description. The wide  square is our docking platform. This small box  

• 00:00:31 is cargo, and the larger block is the courier  body. The equipment housing is new work today,  

• 00:00:38 so the cargo box will remain a separate prop.  Let us first read the station as a place. The  

• 00:00:45 signal attracts the courier to a service platform.  Its path needs enough clearance, and the front of  

• 00:00:53 the courier needs a direction you can recognize.  Notice how the platform, mast, and courier already  

• 00:01:01 have different sizes. Those large shapes make the  scene readable. We will improve the rim, opening,  

• 00:01:08 and front silhouette before spending time on small  decoration. I will select the platform and frame  

• 00:01:15 it using the controls from lecture 1. The Item  panel shows its dimensions. It is 2.4 metres  

• 00:01:22 across and 0.2 metres thick. The platform top is  at 0.2 metres. That leaves a small thickness for  

• 00:01:31 a recess, so its depth matters. An opening should  have a usable floor, not simply look convincing  

• 00:01:39 from above. I will select the courier body by its  name in the Outliner. This is useful when another  

• 00:01:46 object fills the view. The selection identifies  our next subject without moving any of the station  

• 00:01:53 geometry. Now frame the courier body. It is 55  centimetres wide, with its front pointing toward  

• 00:02:02 negative Y. We will keep that direction consistent  while shaping the shell, because its later rig  

• 00:02:09 and animation will depend on it. Before changing  the scene, I will save a new modeling version in  

• 00:02:15 our existing blend folder. The original lecture 1  file stays available. We can compare the forms and  

• 00:02:22 return to that starting point whenever useful.  The filename is w02_modeling_v001.blend. Your  

• 00:02:29 drive letter can differ; use the course folder you  already created. The important habit is keeping  

• 00:02:36 the new work separate from the file you started  with. Here is the housing reference supplied  

• 00:02:42 with this lecture. The front view describes the  opening. The side section explains the back wall,  

• 00:02:49 while the 3/4 drawing helps you understand the  depth of the object. The finished housing is 60  

• 00:02:55 centimetres wide, 50 centimetres high, and 40  centimetres deep. Its walls are 5 centimetres  

• 00:03:02 thick. These are dimensions for this particular  teaching prop, not a rule for every product. Look  

• 00:03:09 at the front opening, then the section beside it.  The opening is 50 by 40 centimetres. The cavity  

• 00:03:16 stops before the back, which makes this a hollow  solid rather than a box with every face removed. A  

• 00:03:23 front orthographic drawing is useful for alignment  because its parallel edges do not converge.  

• 00:03:30 The 3/4 drawing explains shape, but matching  that perspective drawing to a front view would  

• 00:03:37 give misleading proportions. Now I will bring the  front reference into Blender. First return to a  

• 00:03:45 front orthographic view. You can use the front  axis on the navigation gizmo, or the View menu,  

• 00:03:52 when your keyboard has no number pad. From the  Add menu, choose Image, then Reference. The  

• 00:03:58 file browser lets us choose the supplied front  image. This creates an image object that we can  

• 00:04:04 align with the model inside the viewport. I will  use the front image in the reference folder. We  

• 00:04:10 have supplied the editable drawing as well as the  image. You can use this reference without buying  

• 00:04:17 an asset or installing an extra modeling tool.  I will name this guide reference housing front,  

• 00:04:23 then move it into a new Reference collection.  The image stays separate from our mesh. Keeping  

• 00:04:29 guides together makes them easy to hide during a  wider inspection. The reference canvas represents  

• 00:04:36 80 centimetres across, including its margin.  Setting that image size to 0.8 places the 60  

• 00:04:45 centimetre outline at the intended scale. The  label margin is not part of the housing. I will  

• 00:04:51 place the reference at the planned housing center.  Set X to 5 centimetres, Y to -75 centimetres, and  

• 00:04:59 Z to 45 centimetres. These coordinates align the  drawing with the object we will build. Now enable  

• 00:05:08 opacity and set it to 30 percent. Choose Front  for the image depth. The reference outline remains  

• 00:05:15 visible over the mesh, while reduced opacity lets  us read the actual geometry underneath the guide.  

• 00:05:23 Image reference objects do not appear in the final  render. Their display controls decide where they  

• 00:05:30 appear while you model. I will keep the guide in  its own collection and hide it until the housing  

• 00:05:37 is ready. As we return to the station, topology  means the arrangement and connections of vertices,  

• 00:05:44 edges, and faces. A useful mesh is not simply  a denser object. Its structure decides which  

• 00:05:52 edits remain easy to make. Let us use a separate  practice cube for the selection tools. I will  

• 00:05:58 select the cargo box, then duplicate it into  a clear area. This keeps our experiments away  

• 00:06:04 from the station geometry. In Object Mode,  selecting this cube selects 1 object. Its  

• 00:06:15 orange outline tells us which object will receive  a transform. I will frame the practice cube so we  

• 00:06:22 can inspect its corners and faces clearly. Press  Tab to enter Edit Mode. The mode label changes,  

• 00:06:29 and now we can select parts of this mesh. The  object still exists, but our actions can change  

• 00:06:35 the geometry stored inside it. These 3 buttons  choose vertices, edges, or faces. I will start  

• 00:06:41 with vertex selection. A vertex is a position; an  edge connects 2 vertices; a face fills a boundary  

• 00:06:49 and gives the surface an orientation. I will  deselect everything and click this visible corner.  

• 00:06:56 Only that vertex becomes selected. Before moving a  selection, read both the highlighted geometry and  

• 00:07:02 the current mode, especially when several objects  overlap in the view. Now choose the edge selection  

• 00:07:09 button and click a front edge. Blender highlights  the connected line instead of a single point. The  

• 00:07:16 face button selects a surface, which is what we  will use for the platform recess. I will select  

• 00:07:23 the top face and inspect the result from another  angle. Selecting the face you intend is part of  

• 00:07:29 the operation. A highlighted front face would  produce a different extrusion, even with the  

• 00:07:35 same distance. The top row number keys provide  the same component choices: 1 for vertices,  

• 00:07:42 2 for edges, and 3 for faces. These are separate  from number pad views. If number pad emulation  

• 00:07:49 uses those keys, use the buttons instead. The A  key selects all mesh components. Alt A deselects  

• 00:07:57 them in this keymap. The Select menu also exposes  those commands, so you can find their names and  

• 00:08:03 the shortcuts used by your installed keymap. For  a region of points, switch to vertex mode and use  

• 00:08:11 Box Select. Drag around the upper visible corners.  With X Ray off, the front surfaces prevent this  

• 00:08:17 selection from reaching the hidden vertices behind  them. Return to front view, turn on X Ray, and  

• 00:08:24 repeat the box selection. The rectangle reaches  both front and back vertices. The faint geometry  

• 00:08:30 is useful, but it also means an unseen point can  be selected. I will orbit slightly to inspect the  

• 00:08:39 full selection, then turn X Ray off. Looking  from another direction answers which points  

• 00:08:46 we selected. It is a better check than assuming  the rectangle contained only the visible surface.  

• 00:08:53 In face mode, select 1 side and hold Shift while  selecting its neighbor. Both faces belong to the  

• 00:09:00 selection; the last selected face is active. That  active element can matter for tools that need a  

• 00:09:07 reference. Selection growth expands a connected  region rather than finding a new object. I will  

• 00:09:13 grow this selection once, inspect the extra faces,  then shrink it again. Use that shortcut when the  

• 00:09:20 connectivity matches the region you want. Here  is a useful prediction. If I move every vertex  

• 00:09:27 in Edit Mode, will the orange object origin travel  with the mesh? Look at the origin, then pause here  

• 00:09:34 and decide before I make the move. I will move the  selected mesh 30 centimetres along X. The shape  

• 00:09:44 moves, but the object origin stays where it was.  We changed coordinates inside the mesh, rather  

• 00:09:51 than the object's location in the scene. Return  to Object Mode and inspect the Location fields.  

• 00:09:57 They still describe the object origin. The mesh  can therefore sit away from its origin even when  

• 00:10:04 the location values themselves have not changed.  Now move the whole object along X. The origin  

• 00:10:11 travels with it, and its Location value changes.  Object transforms place the mesh in the scene;  

• 00:10:18 editing vertices changes the shape relative  to that object. I will undo the object move,  

• 00:10:25 return to Edit Mode, and undo the mesh offset.  Both layers return to their starting positions.  

• 00:10:31 We will use this distinction when an opening  needs reshaping without relocating the entire  

• 00:10:38 housing. Next, return to Object Mode and rotate  the practice object around Z. The object now has  

• 00:10:46 its own rotated axes. A world direction and an  object direction can differ even though the shape  

• 00:10:53 is still a cube. The transform orientation  control currently says Global. Moving along  

• 00:11:00 X follows the world axis, which stays fixed in  the scene. I will make a small move and watch  

• 00:11:07 its direction against the floor grid. Undo that  move, choose Local in the orientation control,  

• 00:11:16 and move along X again. This time the movement  follows the object's rotated axis. The distance  

• 00:11:23 is unchanged; the direction is what we  chose differently. After the comparison,  

• 00:11:28 I will undo the move and restore Global. Leaving  an unexpected orientation selected can redirect a  

• 00:11:34 later operation. The name in this header is part  of reading the state before a transform. Let us  

• 00:11:42 return the cube to an unrotated state and stretch  it along 1 axis. The visible shape changes,  

• 00:11:49 and its Scale field changes too. Mesh coordinates  and object scale are both contributing to the  

• 00:11:56 displayed size. Here is the 2nd prediction.  When I apply this scale, should the visible  

• 00:12:02 object become smaller, or should its displayed  size stay the same? Pause and compare that  

• 00:12:09 question with the Scale and Dimensions fields.  Open operator search with F3, type Apply Scale,  

• 00:12:20 and confirm that command. The dimensions stay the  same while the scale values return to 1. Blender  

• 00:12:27 has incorporated that scaling into the mesh  itself. A bevel measured in metres is easier to  

• 00:12:35 reason about with applied scale. Apply transforms  according to the operation you need. Here we want  

• 00:12:42 physical widths to match the dimensions of the  form we are editing. I will place the practice  

• 00:12:49 object in a new Studies collection. Keeping our  selection experiments together makes them easy to  

• 00:12:55 revisit. Then hide the practice object and return  to the platform to begin its modeling operations.  

• 00:13:09 Now we can give the platform a useful rim. I  will apply its existing scale while keeping its  

• 00:13:16 size unchanged. Its top remains at 0.2 metres,  and the object is ready for mesh editing. Enter  

• 00:13:24 Edit Mode and choose face selection. Switch  to top view, then select the top face. This  

• 00:13:30 selection decides where the rim is built. The  side and underside faces should remain unselected  

• 00:13:37 while we introduce the inset. Inset Faces creates  an inner boundary inside the selected surface.  

• 00:13:44 It gives us a smaller center face surrounded by a  border. The outer silhouette stays the same, which  

• 00:13:51 is exactly what a platform rim needs. Press I for  Inset Faces and enter 0.12. Confirm the value.  

• 00:13:59 The 12 centimetre border is now geometry around  the center face, and that center remains selected  

• 00:14:06 for the next operation. The last operation panel  exposes the inset thickness and related options.  

• 00:14:13 I will expand it so you can connect the number  to the visible border. A uniform physical rim  

• 00:14:19 begins with an appropriate selection and applied  scale. Now we want the center lower than the rim.  

• 00:14:26 Extrude creates new geometry and moves the  new region. Press E, constrain the move to Z,  

• 00:14:32 and enter -0.08 before confirming. From above, the  recessed floor can look flat. In side view, enable  

• 00:14:43 X Ray to see the floor through the outer wall. An  8 centimetre recess in this 20 centimetre platform  

• 00:14:52 leaves 12 centimetres underneath. Turn X Ray off  after the check. I will inspect it from a 3/4 view  

• 00:15:01 as well. The vertical inner walls connect the rim  to the floor. This connection is why an extrusion  

• 00:15:08 is different from moving the old center face  on its own. The top outline is still 2.4 metres  

• 00:15:15 across. We changed the interior structure without  resizing the platform. That is a useful 1st test:  

• 00:15:22 compare the shape you meant to change with  nearby geometry that should stay put. We will  

• 00:15:28 add 1 raised mounting pad inside this recess.  The selected floor is a suitable starting face.  

• 00:15:35 A 2nd inset will define the pad footprint while  leaving a broad flat area around it. Inset the  

• 00:15:42 floor by 0.7 metres. That leaves a square center  76 centimetres across. This number follows from  

• 00:15:50 our existing opening; a different platform size  would need a different footprint. I will extrude  

• 00:15:58 this smaller center upward by 3 centimetres. The  new side faces connect it to the floor. We are  

• 00:16:05 making an attached pad; a removable piece would  usually be easier to manage as a separate object.  

• 00:16:11 Repeat Last runs the previous operation with  its settings. With the same new top selected,  

• 00:16:17 Shift R adds another 3 centimetre extrusion. It  repeats the operation, so checking the selection  

• 00:16:23 is still our responsibility. The pad now rises 6  centimetres above the recessed floor. Its top is  

• 00:16:32 slightly below the outer rim. Look from the side  with X Ray to compare those 3 levels: floor, pad,  

• 00:16:41 and rim. Turn X Ray off after the check. Extrusion  also has an important cancellation detail.  

• 00:16:48 Canceling only its movement can leave new geometry  in place. If that happens in your own work,  

• 00:16:54 undo the extrusion and inspect the selection and  mesh statistics before continuing. Here the added  

• 00:17:01 faces have a purpose: they form the recessed walls  and the 2 pad steps. I will inspect the visible  

• 00:17:08 edges and counts on this working mesh. More faces  are useful only when they support a shape or  

• 00:17:14 edit. Return to Object Mode and save the platform  checkpoint. Its rim, floor, and pad are connected,  

• 00:17:22 and the overall station scale is unchanged. Next  we will use edge placement to give the courier a  

• 00:17:28 clearer front. The courier should read as a  small machine before it has eyes or detailed  

• 00:17:36 materials. I will select its body and frame it. A  sloped upper front will give this cube a clearer  

• 00:17:44 direction and a more deliberate silhouette.  First I will duplicate the original body in  

• 00:17:50 place and name the copy as a backup. Canceling  the duplicate movement keeps it in exactly the  

• 00:17:56 same position. This gives us the original shape  to recover later. Move that copy into a new Backup  

• 00:18:04 collection. Keeping recovery copies together makes  their purpose clear. Hide the backup, then select  

• 00:18:11 the original body again. Only the original  should receive the mesh edits that follow.  

• 00:18:17 The body already has scale values of 1. That is  the state we want before adding a measured bevel.  

• 00:18:24 I will confirm the scale, enter Edit Mode, and  inspect the simple cube structure before adding an  

• 00:18:30 edge. A loop cut adds a continuous row through a  suitable strip of faces. It works well around this  

• 00:18:38 cube because the side faces form a connected quad  strip. A face with many sides can interrupt that  

• 00:18:44 route. Use Loop Cut, Control R, and hover over a  vertical edge. The preview shows a horizontal loop  

• 00:18:52 around the body. Click to create it, then right  click to center the slide without undoing the new  

• 00:18:58 loop. This loop gives us a shoulder boundary. It  adds control where the front will change slope,  

• 00:19:05 rather than adding subdivisions everywhere. I will  look from the side so its height is easy to read  

• 00:19:12 against the body. Edge Slide moves an existing  edge row along its neighboring edges. Press G  

• 00:19:19 twice and slide this loop a small distance. Notice  how the outer flat sides stay on the same surface  

• 00:19:26 while the row changes position. I will return  the loop to its centered position for our shell.  

• 00:19:33 An ordinary unconstrained move can change the  surface differently. Choose the operation from the  

• 00:19:39 intended change, rather than using slide whenever  an edge happens to be selected. To shape the upper  

• 00:19:46 front, we need its 2 top vertices, including  the hidden one. I will use a side view and X Ray  

• 00:19:54 for this selection. The lower front and the back  should remain unselected. Move that selected pair  

• 00:20:02 12 centimetres toward positive Y. The upper front  moves inward while the shoulder stays in place.  

• 00:20:09 This creates a sloped front surface, and the body  keeps its original width and overall height. Turn  

• 00:20:17 X Ray off and inspect the front, then the 3/4  silhouette. The 2 sides stay symmetrical. The new  

• 00:20:24 slope is a large shape change that will remain  visible even when the courier is small in the  

• 00:20:30 final image. In face mode, select the sloped front  face. Its normal points away from that surface.  

• 00:20:39 A normal describes a direction, not a point,  and that direction is different from the world  

• 00:20:45 Z axis on this sloping panel. The orientation  control decides what an axis name means during  

• 00:20:54 a transform. Global follows the scene axes. Local  follows the object axes. Normal uses the selected  

• 00:21:02 surface direction, which is useful when adjusting  the depth of a sloped panel. Choose Normal,  

• 00:21:09 then move the selected face a small distance along  its Z axis. The movement follows the face normal.  

• 00:21:17 Watch the side view: the panel moves both  horizontally and vertically relative to the  

• 00:21:22 world grid. Undo that change and switch back to  Global. Now make the same small Z move with the  

• 00:21:30 same face selected. It follows the world vertical  direction, so the relationship with the panel is  

• 00:21:37 visibly different. The distance was the same  in both cases. What changed was the basis used  

• 00:21:43 to interpret the axis. For a surface depth, its  normal can be appropriate; for alignment with the  

• 00:21:50 station floor, a world axis is often clearer.  I will undo the comparison move and leave the  

• 00:21:57 orientation at Global. Our chosen shell shape  is restored. Reading the header and the active  

• 00:22:03 selection before a transform prevents a later  operation from quietly using the wrong direction.  

• 00:22:10 The body has a readable front, but its upper  corners are sharp. A small bevel will soften them.  

• 00:22:17 First return to Object Mode. We will preserve  this shaped mesh before changing its upper  

• 00:22:23 edges. Duplicate the shaped body in place and name  this copy as the pre bevel backup. It records the  

• 00:22:31 shoulder and sloped front. That earlier structure  will be useful when we explore an adjustable  

• 00:22:37 bevel next lecture. Move this copy into the Backup  collection with our original cube. Hide the copy,  

• 00:22:45 then select the working courier again. We can  now bevel the visible body while keeping both  

• 00:22:52 earlier versions available for comparison. Return  to Edit Mode and choose edge selection. Select the  

• 00:22:59 upper perimeter edges. We are rounding a chosen  part of the silhouette, not subdividing every  

• 00:23:05 surface. Inspect the selection from above before  applying the width. Press Control B for Bevel and  

• 00:23:13 enter 0.02 metres. Use 2 segments for this small  transition, then confirm. The width is modest  

• 00:23:21 compared with a body that is 55 centimetres  across. The operation panel shows the width  

• 00:23:27 and segment count. Increasing segments changes  the transition geometry, but it does not repair  

• 00:23:34 poor edge placement or unwanted overlaps. First  choose the silhouette and width that the shape  

• 00:23:40 actually needs. Look from the front and side,  then return to the 3/4 view. The corners have  

• 00:23:47 a controlled transition, and the main silhouette  still reads clearly. We have added detail where it  

• 00:23:53 changes the outline and catches light. This edit  is part of the mesh now. Next lecture, a Bevel  

• 00:24:00 modifier will keep similar settings adjustable.  Our pre bevel copy lets us explore that reversible  

• 00:24:08 route without trying to reconstruct the earlier  shape by hand. Return to the practice object for  

• 00:24:15 another coordinate comparison. I will reveal it  and frame it in the viewport. There is also a  

• 00:24:20 shortcut for changing the active constraint during  a transform, without changing the header first.  

• 00:24:30 Rotate the practice object 30 degrees around Z.  Its local axes now differ from the scene axes.  

• 00:24:37 That visible rotation will help us read which  direction the current constraint follows while  

• 00:24:43 we press the same axis key again. With Global  selected, start a move and press X once. The  

• 00:24:50 constraint follows world X. Press X again and the  operation uses the object's local X axis. Watch  

• 00:24:57 the direction line and the orientation name while  it changes. Pressing the axis a 3rd time releases  

• 00:25:03 that constraint. I will cancel this movement after  showing the 3 states. This shortcut changes the  

• 00:25:10 current operation; it does not require changing  the header for every individual move. The meaning  

• 00:25:15 of repeated axis presses depends on the current  orientation, so read the displayed name rather  

• 00:25:22 than memorizing a direction on the screen. I  will restore the practice object and hide it  

• 00:25:27 again before continuing with the housing.  Now we will build the equipment housing as  

• 00:25:34 a new object. It is separate from the existing  cargo box. We will start with a square front,  

• 00:25:40 then widen 1 side while preserving the wall  thickness shown in our reference. Add a cube  

• 00:25:48 and name it equipment housing. I will set its  width and height to 0.5 metres and its depth to  

• 00:25:56 40 centimetres. This gives us a manageable solid  block before we create the opening. The Item panel  

• 00:26:03 lets us enter those dimensions exactly. Width  is 0.5, depth is 0.4, and height is 0.5. These  

• 00:26:12 values describe the outside of the housing, before  any cavity exists. Place it in front of the signal  

• 00:26:19 with its base at platform height. Its center is  45 centimetres above the ground. The vertical  

• 00:26:27 position follows the 0.5 metre height, rather than  a guessed visual offset. Apply the scale while  

• 00:26:34 keeping outside dimensions. The values return to  1, ready for our wall. Now frame the housing so  

• 00:26:42 its outline fills a useful part of the viewport.  Switch to front view. We will select the negative  

• 00:26:49 Y face to create the opening. Enter Edit Mode  and choose face selection. Select the front face,  

• 00:26:56 then inset it by 5 centimetres. The smaller square  is the opening boundary, while the border will  

• 00:27:02 become the front wall around our cavity. Extrude  the inner face inward by 35 centimetres. Here  

• 00:27:10 inward is positive Y, because the front faces  negative Y. The outer depth is 40 centimetres,  

• 00:27:17 so this leaves a 5 centimetre back wall. From  the 3/4 view, we can see the cavity and its  

• 00:27:24 back surface. The inner walls connect the opening  to that back. An opening is useful only if the  

• 00:27:30 intended surfaces remain connected around its  empty space. Switch to side view and enable X  

• 00:27:37 Ray. We can now see the cavity depth through the  outside surface. The inner back is 5 centimetres  

• 00:27:45 from the outer back. Turn X Ray off after checking  that separation. The front boundary is open to the  

• 00:27:52 cavity, but the housing material forms a closed  solid shell. That distinction matters during  

• 00:27:58 cleanup. A hole leading into a box is different  from a missing face in the box wall. The reference  

• 00:28:06 asks for a rectangular opening. We currently  have a square one. Before changing it, pause  

• 00:28:12 and decide which vertices should move: only the  inner edge, or both inner and outer boundaries on  

• 00:28:18 that side? Switch to vertex mode and enable X Ray.  Select the entire right side through the depth,  

• 00:28:28 including its outer and inner vertices. Moving  these points together preserves their separation;  

• 00:28:35 moving only the inner boundary would change  the wall thickness. Move the selection 10  

• 00:28:41 centimetres along positive X. The outside  width becomes 60 centimetres and the opening  

• 00:28:47 becomes 50 centimetres. The 5 centimetre wall  still separates the corresponding inner and  

• 00:28:53 outer boundaries. Turn X Ray off and show the  reference outline. The height has not changed,  

• 00:28:59 and the new width matches the front drawing. We  changed the intended region without scaling every  

• 00:29:05 wall thickness across the whole object. Hide  the reference after comparing its outline with  

• 00:29:10 the housing. A matching front silhouette does not  establish the depth by itself. Return to the 3/4  

• 00:29:18 view and inspect the cavity. Its back wall remains  in place after our width revision. Select Linked  

• 00:29:25 is useful when you want a connected island. Hover  over this shell and use L to select its connected  

• 00:29:31 geometry. Separate loose pieces would not join the  selection merely because they belonged to the same  

• 00:29:38 object. Return to Object Mode. The housing can  stay separate from its lid and removable panel,  

• 00:29:45 because those pieces need different edits or  movement. Sharing a purpose does not mean several  

• 00:29:52 parts must become 1 mesh. I will add a separate  cube for the lid and give it the housing width  

• 00:30:00 and depth. Its thickness is 4 centimetres. Keeping  a slight space above the shell makes the removable  

• 00:30:07 construction easy to read. Set the lid to 60  centimetres wide, 40 deep, and 4 thick. Those  

• 00:30:14 dimensions match the widened housing footprint.  The small thickness makes this a lid rather than  

• 00:30:21 another large block above the shell. Place its  center at X 0.05, Y -0.75, and Z 0.73. That leaves  

• 00:30:31 a small gap above the housing. We can move this  lid without selecting the housing's own vertices.  

• 00:30:39 Add another cube for the removable panel and name  it Housing Panel. This uses the same separate  

• 00:30:45 object idea. We will give it a shallow thickness  and place it beside the housing so the opening  

• 00:30:52 remains visible. Make the panel 0.5 metres wide,  3.5 centimetres thick, and 40 centimetres high.  

• 00:31:00 These dimensions give us a simple removable part  to inspect. Its shape can change independently  

• 00:31:06 from the connected housing walls. Place the panel  beside the housing. Set X to -0.65, Y to -0.9,  

• 00:31:15 and Z to 0.42. Its lower edge is just above  the platform, and both parts remain readable.  

• 00:31:25 Add a plane and name it Bridge Study. We will  build a short connector from 2 matching open  

• 00:31:31 loops. Bridge Edge Loops creates surfaces between  boundaries, which is different from filling 1  

• 00:31:37 boundary with a single face. Make this plane 30  centimetres across in both X and Y. Its height  

• 00:31:44 stays 0 because it is a flat surface. Apply its  scale once those dimensions are set. The square  

• 00:31:51 defines the cross section of our connector.  Place the study at -3 on X, -1 on Y, and 0.3 on  

• 00:32:00 Z. Frame it so the construction is easy to see.  Working beside the station keeps our experiment  

• 00:32:07 separate from its useful geometry. Enter Edit  Mode and select the plane. Remove only its face,  

• 00:32:13 leaving the 4 boundary edges and their vertices.  This is an intentional construction step: those  

• 00:32:20 edges define 1 end of our connector, ready for a  2nd matching loop. Duplicate the selected boundary  

• 00:32:27 and move the copy upward. We now have 2 loops with  the same number of vertices. Their corresponding  

• 00:32:34 corners provide a straightforward connection  for the bridge operation. Select both loops and  

• 00:32:42 choose Bridge Edge Loops from the Edge menu or the  operator search. Blender creates the connecting  

• 00:32:48 side faces. I will inspect the result from an  angle so we can see that the ends remain open.  

• 00:32:55 These open ends are deliberate boundaries in this  study. Filling 1 end would create a cap; bridging  

• 00:33:02 connected the 2 ends along their sides. Choose  between those operations by asking which surface  

• 00:33:08 is actually missing from the intended form. Select  the upper boundary from the side using vertex  

• 00:33:14 selection and X Ray. The 4 upper corners should  be selected, with the lower loop left alone. Turn  

• 00:33:22 X Ray off once that boundary is clear. Press F  to fill this selected boundary. A single flat  

• 00:33:28 face is reasonable for this static cap. It would  need more consideration if we later wanted to bend  

• 00:33:36 or subdivide this region, because that later  edit changes what the topology must support.  

• 00:33:46 A bridge can twist when its correspondence  does not match your intention. Inspect the  

• 00:33:51 side connections and the operation settings while  the result is visible. Matching counts help here,  

• 00:33:57 but the resulting surface still deserves a look  from several directions. Keep this connector  

• 00:34:03 in the Studies collection and hide it. Its open  end and capped end remain available in the file.  

• 00:34:10 Return to the station. We have used a connected  housing shell and independent removable parts,  

• 00:34:16 choosing construction from the changes each part  should support. This is a useful point to save our  

• 00:34:24 modeling version. We now have a recessed platform,  a shaped courier, and a hollow equipment housing.  

• 00:34:31 I will save the current file before moving into  geometry diagnostics. Return to Object Mode and  

• 00:34:38 frame the station. Framing changes the view, not  the position of the objects. If your model seems  

• 00:34:44 to disappear, first check which object is selected  and which view you are looking through. Our  

• 00:34:50 courier still has its own origin, and the housing  has another. Within each object, the mesh holds  

• 00:34:57 the vertices we changed. This is the same 2 layer  relationship we tested on the practice cube. The  

• 00:35:04 supplied checkpoints match the completed building  steps. Use the platform checkpoint for the recess,  

• 00:35:10 the shell checkpoint for edge placement, or this  modeling save to begin the cleanup discussion  

• 00:35:16 with the same geometry on screen. I will select  the housing and frame it for a surface check. A  

• 00:35:24 clean silhouette is only part of a useful model.  Enable Face Orientation so we can read which way  

• 00:35:30 the surfaces face. In this theme, front facing  surfaces keep their normal shading, while back  

• 00:35:39 facing surfaces turn red. Inside the cavity,  the inner walls face into the empty space. That  

• 00:35:45 is consistent with the outward direction of this  closed housing shell. A normal gives a surface its  

• 00:35:54 facing direction. It helps define orientation and  affects how the surface responds to lighting. It  

• 00:36:01 does not say whether the mesh has the right number  of walls or whether surfaces overlap. Select the  

• 00:36:07 intended geometry and choose Recalculate Outside.  This command is useful for inconsistent face  

• 00:36:14 directions on a connected solid. Our working shell  already faces outward, so its orientation stays  

• 00:36:20 consistent after this operation. That operation  changes orientation; it does not create a  

• 00:36:27 missing wall or remove overlapping faces. If your  shading still looks odd, inspect the structure. A  

• 00:36:34 different color is a clue about direction, not  a complete diagnosis. The word outside needs  

• 00:36:40 context. A platform or housing wall is intended as  a solid. A future banner or leaf can intentionally  

• 00:36:48 be a thin sheet. Their valid boundaries differ,  so the same selection result can mean different  

• 00:36:54 things. I will inspect the cavity from the side  with X Ray. The back face is separated from the  

• 00:37:02 outer back by 5 centimetres. The cavity stops  inside the body; it does not pass through that  

• 00:37:10 rear wall. Turn X Ray off and return to Object  Mode. Press number pad slash for Local View,  

• 00:37:17 temporarily isolating the housing. Now inspect  its underside and rim connections. The intended  

• 00:37:24 outer and inner surfaces stay connected around the  opening. I will restore the upright view and turn  

• 00:37:31 Face Orientation off after the check. Diagnostic  overlays are useful for answering a question.  

• 00:37:37 Keeping every overlay visible all the time can  make the shape itself harder to read. Add a plane  

• 00:37:44 and name it Merge Study. We will make 2 adjoining  sections and connect their matching boundary  

• 00:37:52 points. Merge by Distance combines nearby vertices  within a chosen threshold; it is useful for a  

• 00:38:00 specific seam rather than as a general repair  button. Make this plane 30 centimetres across in  

• 00:38:06 X and Y. Its dimensions match the small connector  study. Apply its scale next, keeping that square  

• 00:38:14 footprint. This time we will extend the surface  sideways and connect the matching boundary points.  

• 00:38:21 Place this study at -3 on X, -1.6 on Y, and 0.3  on Z. Frame it in the viewport. This gives our  

• 00:38:31 seam example room beside the other studies without  changing the station. Enter Edit Mode and select  

• 00:38:38 the plane, then duplicate the selected geometry  30 centimetres along X to meet the original edge.  

• 00:38:45 Their boundary vertices now occupy matching  positions, but duplication has not connected  

• 00:38:51 those corners into a shared seam yet. Frame both  squares together so their full outer boundary  

• 00:38:57 is visible. The new section extends the original  footprint, but the seam still contains 2 copies of  

• 00:39:04 each matching corner. We will select that shared  boundary without including the outer corners.  

• 00:39:10 In top view with X Ray, select only the seam  region. Both copies of each matching corner must  

• 00:39:16 be included. Turn X Ray off after the selection.  Limiting the region keeps unrelated small details  

• 00:39:25 outside the merge operation. Choose Merge by  Distance and use a conservative threshold.  

• 00:39:32 The matching seam points can merge without  reaching a neighboring feature. I will read  

• 00:39:36 the reported removal count and inspect the edge  connection after the operation. A larger threshold  

• 00:39:44 can combine points that should stay separate.  If the result changes the shape unexpectedly,  

• 00:39:50 undo and reduce that distance or tighten the  selection. We are keeping the working seam clean  

• 00:39:56 rather than introducing damaged geometry. The  statistics help us account for the intended merge.  

• 00:40:03 They do not explain the purpose of every remaining  face. I will inspect the join in wireframe and  

• 00:40:09 from an angle, checking that the surface still  has the shape we wanted. Auto Merge is a different  

• 00:40:16 behavior. When enabled, it can merge vertices  as you move them together. That can be useful  

• 00:40:22 for deliberate welding, but it also changes what  an ordinary drag may do near another vertex. For  

• 00:40:30 these construction examples, I am leaving Auto  Merge disabled. Our merges happen as explicit  

• 00:40:36 operations on a chosen selection. You should know  its state before a move, rather than discovering  

• 00:40:42 afterward that 2 nearby points became 1. Keep the  merged example in the Studies collection and hide  

• 00:40:49 it after inspection. Its 2 connected faces remain  available in the companion file. We will return to  

• 00:40:57 the housing for a different question: whether its  intended solid shell has an open mesh boundary.  

• 00:41:04 Select the equipment housing by its name in the  Outliner. This works even when our close view is  

• 00:41:11 still centered on a study. Frame the housing  so we can inspect its complete shell and the  

• 00:41:18 opening we deliberately built into it. Enter Edit  Mode and use vertex selection. Deselect the mesh,  

• 00:41:25 then choose Select Non Manifold. It  highlights boundaries or connections that  

• 00:41:30 deserve investigation. For this closed shell, the  intended result is no selected boundary edges. An  

• 00:41:37 empty selection means this shell has no selected  open mesh boundary. For overlapping surfaces,  

• 00:41:43 inspect the cavity, thickness, and wireframe  as well. Each check answers a specific question  

• 00:41:49 about the geometry rather than replacing the other  inspections. The connector study intentionally has  

• 00:41:56 an open end, so its boundary would be selected.  That is a question about its intended use, not  

• 00:42:02 automatic damage. Always interpret a diagnostic  result in relation to the form you are building.  

• 00:42:10 Vertices and faces should support the form and its  next changes. The platform has broad flat regions,  

• 00:42:17 while the courier has a controlled shoulder and  rounded edges. Their useful topology need not look  

• 00:42:25 identical. Select the platform by name in the  Outliner. Its broad flat regions make a useful  

• 00:42:32 contrast with the courier shoulder. Frame the  platform so we can inspect its divisions and  

• 00:42:38 think about what a later edit would require.  Enter Edit Mode to inspect these faces. Quads  

• 00:42:45 are convenient for loop based edits and many  subdivision patterns. Triangles can suit a  

• 00:42:53 stable surface. An n gon can work on a flat static  panel when its triangulation and intended use are  

• 00:43:02 understood. A bend or subdivided transition needs  more deliberate edge placement than a flat cap.  

• 00:43:09 Adding more faces does not automatically improve  it. First ask where the silhouette changes,  

• 00:43:14 where deformation happens, and which later  operation needs those connections. Smooth  

• 00:43:20 shading changes how lighting is interpolated  across a surface. It does not add silhouette  

• 00:43:26 geometry or repair a missing wall. Inspect the  outline from front and side views before using a  

• 00:43:33 shading change to judge the model. We have checked  applied scale, surface direction, intended walls,  

• 00:43:40 and the seam operation. I will save the clean  modeling state now. Those specific checks make the  

• 00:43:47 file easier to revise than simply adding detail  until it looks complicated. Let us reuse the  

• 00:43:55 same grammar on 1 smaller docking tray. This time  the outside is 70 centimetres by 45 centimetres.  

• 00:44:04 We will keep its border thin enough to read, then  revise the opening by moving a selected side. Set  

• 00:44:12 the outside dimensions to 70 centimetres across  X, 45 across Y, and 13 in height. The thickness  

• 00:44:19 must accommodate both the cavity and its floor.  This separate prop has its own origin and editable  

• 00:44:26 mesh. Place its center at -0.5 metres along  X and -0.35 along the Y axis. Set Z to 0.185,  

• 00:44:38 then frame the tray to see its full outline  before creating the cavity. Apply scale to keep  

• 00:44:47 the measured border predictable. The dimensions  stay the same while scale returns to 1. Enter  

• 00:44:54 Edit Mode, choose face selection, and look from  above. Select the top face as the starting surface  

• 00:45:01 for our cavity. Inset the top by 4 centimetres,  then extrude the center down by 8 centimetres.  

• 00:45:10 That leaves a 5 centimetre floor below the  opening. The depth follows the thickness we need,  

• 00:45:16 rather than just its appearance. Inspect the tray  from the side with X Ray. Its border and floor  

• 00:45:24 are now visible through the outer wall. The same  inset and extrusion steps made a different result  

• 00:45:30 because we chose different starting proportions  and distances. From top view, switch to vertex  

• 00:45:37 selection and keep X Ray enabled. Select both the  outer and inner boundary on the right side through  

• 00:45:43 the depth. Their spacing is the wall thickness  we want to preserve during this revision. Move  

• 00:45:49 the selected points 8 centimetres toward negative  X. The tray becomes narrower on that side while  

• 00:45:56 the border thickness stays consistent. This is  the same boundary choice we used on the housing,  

• 00:46:02 now applied to a different footprint. Turn X Ray  off and compare solid and wire views. Look for  

• 00:46:10 the intended floor, wall, and outer outline. The  result should remain a useful tray from the camera  

• 00:46:16 direction as well as from this close working view.  I will save this completed tray with the station.  

• 00:46:23 We do not need another tray for the recap; this  variation already shows the transferable idea.  

• 00:46:30 Familiar operations stay useful when the selection  and construction decisions are clear. Now let us  

• 00:46:38 change the subject while keeping the same modeling  logic. We will make 1 simple architectural niche,  

• 00:46:46 separate from the station. Reference dimensions,  connected walls, and surface checks matter at  

• 00:46:53 building scale just as they did for our prop. Make  this study 1.6 metres wide along X, 2 metres high,  

• 00:47:02 and 60 centimetres deep. Those outside dimensions  establish a tall architectural form. Its front  

• 00:47:09 opening will use a wider border than the equipment  housing, appropriate to this larger example. Place  

• 00:47:17 it 4 metres along X, 0 on Y, and 1 metre above the  ground. The 2 metre height then leaves its base  

• 00:47:27 at ground level. Frame the niche so we can see  the whole form while building its opening. Apply  

• 00:47:35 scale to keep the measured border predictable. The  dimensions stay the same while scale returns to  

• 00:47:41 1. Enter Edit Mode, choose face selection, and  look from the front. Select the front face as  

• 00:47:48 the starting surface for this opening. Inset that  face by 15 centimetres, then extrude the center 45  

• 00:47:56 centimetres inward. The 60 centimetre body leaves  a 15 centimetre back wall. Inspect the cavity  

• 00:48:03 from the side before changing its silhouette. The  niche now uses the same connected wall structure  

• 00:48:10 as our equipment housing. Its proportions give it  a different purpose. An operation becomes easier  

• 00:48:17 to reuse when you recognize the geometric  relationship rather than only memorizing  

• 00:48:22 a shortcut sequence. To make a wedge shaped  variation, select the upper vertices through  

• 00:48:29 the depth. We will move the upper region sideways  while leaving the base in place. The outer and  

• 00:48:35 inner upper boundaries move together, preserving  their useful separation. Move that upper selection  

• 00:48:42 25 centimetres along X. The silhouette becomes  slanted, and the opening follows it. We are  

• 00:48:48 changing vertex positions within the object, which  is why the object origin does not travel with the  

• 00:48:54 top. Turn X Ray off and inspect the front, side,  and 3/4 views. The base stays level and the back  

• 00:49:01 wall remains present. The same coordinate and  solid boundary ideas transferred from a small  

• 00:49:06 housing to this larger architectural form. A Knife  cut is useful for a specific path across faces,  

• 00:49:14 while Bisect cuts along a plane. This niche  already has the structure its shape needs,  

• 00:49:22 so neither tool is required here. Extra cuts  should answer a visible construction need.  

• 00:49:28 Return to Object Mode and move the niche into the  Studies collection. You can inspect it beside the  

• 00:49:34 housing example in the companion files. Save the  result after organizing it. The shared ideas are  

• 00:49:41 selection, proportions, connected walls,  and deliberate silhouette changes. Add a  

• 00:49:48 plane and name it Dissolve Study. Delete and  Dissolve answer different questions. We will  

• 00:49:53 divide this clean surface into 2 faces, giving  us a simple case where removing the center edge  

• 00:49:59 can preserve the surrounding boundary. Make this  strip 60 centimetres wide in X and 30 centimetres  

• 00:50:07 deep in Y. Its height remains 0. Apply its scale  after setting those dimensions. A flat rectangular  

• 00:50:14 surface makes the effect of the 2 commands easy to  compare. Place this study at -3 on X, -2.2 on Y,  

• 00:50:24 and 0.3 on Z. Frame it in the viewport. We are  keeping the demonstration beside the station  

• 00:50:30 rather than cutting a useful finished prop. Enter  Edit Mode and look from above. Use Loop Cut on an  

• 00:50:37 edge running across the strip, then center its  slide. We now have 2 flat faces divided by 1  

• 00:50:44 internal edge, while the outside outline remains  the same rectangle. Select the center edge between  

• 00:50:51 the 2 flat faces. This edge divides the surface  without changing its outer boundary. Choose  

• 00:51:00 Dissolve Edges to remove that internal division  while keeping the surface. We have simplified the  

• 00:51:07 structure without making an opening. Undo to  recover the original strip. This time Delete  

• 00:51:14 Edges removes the selected edge and the faces that  depend on it. The missing surface is the intended  

• 00:51:20 result of that command, rather than a shading  change. I will undo again and keep the useful  

• 00:51:27 strip. Dissolve preserved a surface by removing  an internal element; Delete removed geometry.  

• 00:51:34 Neither is always better. Choose according to  whether the surface or boundary should continue  

• 00:51:40 to exist. We are keeping the original strip with 2  flat faces. Faces with more than 4 sides can work  

• 00:51:47 on flat, static regions. Bending or subdividing  such regions requires checking how the surface  

• 00:51:55 is divided and evaluated. Move the strip to  Studies and hide it after this comparison.  

• 00:52:02 Delete and Dissolve now have visible meanings.  We will return to the architectural niche next,  

• 00:52:08 using temporary visibility to reach useful  geometry without deleting any part of the model.  

• 00:52:14 Select the architectural niche by name and frame  its outline. We can now compare object isolation  

• 00:52:20 with hiding a selected mesh region. Both help  us reach geometry, but they work at different  

• 00:52:25 levels and leave the underlying model available.  Sometimes the geometry is correct but difficult  

• 00:52:34 to reach. Local View temporarily isolates  the selected object in this viewport. I will  

• 00:52:40 use it on the niche so other scene objects stop  competing for the same screen space. Local View  

• 00:52:48 has not deleted or moved the station. It changes  which objects this viewport shows. The View menu  

• 00:52:55 provides the same command if your keyboard does  not have the number pad slash shortcut. Enter Edit  

• 00:53:02 Mode and choose face selection. Select the right  side, then use Hide Selected so we can inspect the  

• 00:53:09 cavity from another angle. The geometry remains  in the object, ready to reveal again. Reveal  

• 00:53:16 Hidden restores that region. Notice that Hide and  Reveal affect what you can select while working;  

• 00:53:23 they do not rebuild a missing surface. Check  hidden geometry before assuming an apparently  

• 00:53:29 empty area was deleted. Select Linked finds  connected geometry, while Local View isolates  

• 00:53:35 selected objects. Those are different levels of  organization. I will inspect the connected niche,  

• 00:53:40 return to Object Mode, and leave Local View to  recover the wider scene. Hide the niche and then  

• 00:53:47 the Studies collection. All our practice examples  remain available in the file. Return to the  

• 00:53:53 station view for its final inspection. Temporary  visibility should help us concentrate without  

• 00:54:01 changing which parts belong to the finished  station. Temporarily hide the ground for our final  

• 00:54:08 inspection. The station should have its intended  surfaces from every direction, including the parts  

• 00:54:16 we usually cannot see. Look at the underside now,  checking the solid forms before adding anything  

• 00:54:22 else. The platform keeps its floor below the  recess. The housing keeps its back and side walls,  

• 00:54:29 and the tray has a separate floor. We are checking  the forms we intended to build, not searching for  

• 00:54:35 extra detail to add. Now restore the ground.  Temporary visibility helps during inspection,  

• 00:54:42 but should not quietly change the saved  presentation of the scene. Return to the upright  

• 00:54:48 view and confirm the objects we want visible  before the final save. Compare the lecture 1 view  

• 00:54:55 with our current geometry. The colors and lighting  are not the main improvement today. The platform  

• 00:55:01 has depth, the housing has a usable opening,  and the courier has a readable front. The broad  

• 00:55:08 shapes communicate before small surface details.  Separate objects let us change independent parts,  

• 00:55:15 and the courier still has its earlier backup.  These choices give us a useful starting point  

• 00:55:21 for reversible modeling next lecture. Restore  visibility for the Studies collection. The  

• 00:55:27 individual practice objects remain hidden until  we choose one. This lets us return to a specific  

• 00:55:34 example while keeping the finished station easy  to read around it. Reveal the practice object once  

• 00:55:40 again and frame it for a brief preview of the next  step. We will use this separate study to compare  

• 00:55:47 an adjustable bevel with the direct mesh edit on  our courier. The station geometry can stay as it  

• 00:55:54 is. Use operator search to add a Bevel modifier to  this practice object. Open Modifier Properties to  

• 00:56:02 see its settings. The bevel changes the evaluated  appearance while preserving the original mesh,  

• 00:56:08 giving us a different way to revise the corner  width. I will change that width once and compare  

• 00:56:15 the result. The control remains available in the  modifier stack. Next lecture we will build the  

• 00:56:21 full reversible workflow and examine how the order  of such operations changes the model. For today,  

• 00:56:28 we will keep our explicit modeling baseline  and hide the preview study. The courier's  

• 00:56:34 pre bevel copy is available for the next lesson.  We do not need to rebuild its earlier shape or  

• 00:56:40 merge unrelated props together. Let us connect the  main checks to the finished objects. Applied scale  

• 00:56:47 gave our inset and bevel widths a predictable  basis. Face orientation described surface  

• 00:56:55 direction. Neither one removed an unwanted wall or  repaired overlapping geometry for us. An n gon can  

• 00:57:04 be useful on a flat static region, while a bend  needs more deliberate topology. After canceling an  

• 00:57:11 extrusion movement, inspect for retained geometry.  Before any directional move, read the selection,  

• 00:57:18 mode, and transform orientation. I will save  the finished scene as w02_station_v001.blend.  

• 00:57:26 It contains the refined platform, equipment  housing, and courier shell as separate objects.  

• 00:57:31 The companion checkpoints let you resume from  the corresponding completed steps. Use the final  

• 00:57:39 station file to continue into lecture 3. Keep the  reference images with the course files so their  

• 00:57:46 paths remain available when you reopen the scene.  The supplied folder follows the same structure we  

• 00:57:52 used in lecture 1. We have used 1 small set of  mesh operations across a platform, a housing,  

• 00:57:59 a courier, a tray, and an architectural form.  The important skill is choosing the selection  

• 00:58:05 and direction that produce the change you actually  want. You can find the chapter links, shortcuts,  

• 00:58:12 and checkpoint files in the description. In the  next lecture, we will make these forms easier  

• 00:58:17 to revise with modifiers and other reusable  construction tools. Thank you for watching.
