0.13.1

Smooth sketching; Extrude Cut off the part cuts at once.

Improvements

• While a sketch is open, the view keeps up with the mouse: drawing a rectangle, a line or anything else no longer
  lags behind the pointer (FreeCAD put off redrawing while the mouse kept moving).
• Points are easier to catch on a Mac's Retina screen: the pick radius is doubled once (Preferences > Display > 3D
  View > Pick radius; a value you set yourself stays).
• While a rectangle is drawn, its two diagonals show dashed, for orientation. The finished rectangle gets a
  construction point in its middle: put it on the origin and the rectangle is centred.

Bug fixes

• Extrude > Cut did nothing the first time when the profile lay off the part (it went into its own empty Solid, and
  Cut cut only that); Intersect and then Cut was needed. Cut now cuts the part at once.
• A rectangle's centre point could not be put on an axis: the click took the point's constraint icon. That icon is
  hidden now, also on FreeCAD's Center Rectangle.

ProstoCAD for FreeCAD 0.13.0

ProstoCAD for FreeCAD 0.13.0 (formerly InCad): test build for macOS (Apple Silicon) and Windows 10 / 11 (x64), FreeCAD 1.1 (tested with 1.1.3).

InCad has a new name: ProstoCAD for FreeCAD. Nothing else changes: the same workbench, and every file made before opens as it did. Home page: https://prostocad.com

macOS: ProstoCAD-FreeCAD-0.13.0-2026-10-27-4176e15-macOS-arm64.zip. Install as before (see README.txt in the archive); the module folder is still called InCad, so an existing installation is simply replaced.

0.13.0

InCad is now ProstoCAD for FreeCAD: a new name, the same workbench.

Improvements

• InCad has a new name: ProstoCAD for FreeCAD (the workbench shows as ProstoCAD). Nothing else changes: the same
  tools, and every file made before opens as it did.
• The new home page: https://prostocad.com. The project's GitHub address is now https://github.com/Igr11/ProstoCAD
  (the old address still leads there).
• Install as before: the module folder is still called InCad, so an existing installation is simply replaced.
• The sketch's right-click menu offers Delete for whatever is selected: lines, points and dimensions. A right-click on
  something not selected selects it first, so Delete removes exactly that.
• Parameters: - deletes a sketch dimension (d1, d2...) from its sketch; one that a formula uses stays, and the status
  line says which formula.

Bug fixes

• After Symmetric the lines could not be dragged: the tool stayed on, waiting for another pair, and took every click.
  It now ends once the pair is made.
• Messages said "an InCad part"; they now read "a ProstoCAD part".

0.12.0

Mirror Solid; sketch Mirror that follows its original; InCad's own Symmetric; Parameters window; Split Gap; Report a Bug.

Improvements

• Mirror Solid (3D Model > Pattern): a mirrored copy of a whole Solid as a new Solid. Select the Solid (with several,
  click the one), Mirror Solid, then click the mirror plane - an origin or work plane, or a flat face. The copy
  follows the original - every change, every feature added later - and takes features of its own.
• Mirror Solid > Result: New Solid, Join (the mirror image joined into the same Solid: a half made whole) or Cut (the
  image cut out of it). Mirror: Whole, or only the part on One side / the Other side of the plane - a part crossing
  the plane becomes symmetric with Join.
• Break Mirror Link (right-click a Mirror Solid row or its Solid): the copy keeps its shape and stops following. On a
  feature Mirror it keeps the mirrored material as it is.
• Boolean can use a mirrored Solid as a tool on its own original (Join, Cut, Intersect): the copy then follows the
  original up to the step before that Boolean.
• Sketch > Mirror: select the shapes, Mirror, then click the mirror line - any line (also one of the shape's own), the
  X or Y axis, or a point. The copy keeps the original's size and follows it, and no dimension is copied. Right-click
  the copy > Break Mirror Link frees it.
• Sketch > Symmetric is InCad's own: two points, two lines or two circles, then the symmetry line; it never picks a
  dimension, and stays on until Esc.
• Shift-click a sketch line: its whole outline is selected at once, and shows selected.
• Parameters window (View > Windows > Parameters): every parameter with its value, result and the features that use
  it; add, remove, rename, Find, Delete Unused.
• Split > Gap (in 0.05 mm steps) and Gap from: Both, This Solid or New Solids.
• Settings (gear) > Report a Bug: describe the problem, attach the log, and it goes to InCad's issues on GitHub (this
  build opens GitHub's New Issue page).
• Right-click menus show only what applies to what is under the pointer; the sketch menu is shorter (Constraints
  (n)... opens the list).
• Spur Gears / Worm Gear handles are bigger, coloured by axis, and easier to grab.
• The manual's Known limits list what Mirror Solid and clearances can't do yet.

Bug fixes

• The Parameters button only moved the focus to the small panel: it opens the Parameters window now.
• Symmetric sometimes caught a dimension's point instead of the sketch point.
• Mirror of a chain failed ("other constraints fight it") when its points lay on the mirror line.
• Boolean > Cut with a clearance refused a tool that can't be grown (an Emboss, a thread): it is cut with Clearance 0
  mm now, and the status line says so.
• Sketch Offset lit only the line clicked, not the whole outline it takes.

0.11.4

Every plane of a row can be edited and turned; work features on 3D Line points and work points; work feature fixes.

Improvements

• Double-click a work plane (in the browser or in the view), or Edit on its menu: its Work Plane dialog opens. New
  Sketch on a work plane is on its right-click menu; a right-click on a work plane in the view gives its browser row's
  menu.
• Planes: every plane of a row has its own dialog - its offset along its normal and its own Turn, rings on it. With a
  row's dialog open, a click on another plane of the row keeps what was set and moves the dialog and the rings there.
• Point fields offer a 3D Line's ends and the points it passes through, and work points. Normal to edge at point on a
  segment of a 3D Line and its end gives the plane for a loft along it. A corner of a 3D Line or a work point is kept
  as that point: the work feature follows it.
• Work Plane > Angle around edge and Normal to edge at point take an origin or work axis as the edge.
• Offset and Turn step below zero with the arrows and the mouse wheel.

Bug fixes

• Only the first plane of a row could be turned: the others had no dialog (a double-click started a sketch).
• Planes typed on the second or third plane of a row made a second row on top; it now sets the whole row's count.
• The first plane of a row switched to another method kept the others tied to it; they now stay where they are, as
  planes of their own.
• Angle around edge about an origin axis failed.
• Corners clicked again in a work feature's Edit became fixed points: the feature no longer followed the part.
• On Edit, a work feature took a pick in another Solid and landed in the wrong place; it now says so.
• Work Point > Midpoint of edge on an arc or a curve was off the edge; it is halfway along the edge now.
• Work Point > Edge meets plane and Two edges meet put a point even where nothing meets; they now say so.
• Work Axis > On edge took a circle and placed a meaningless axis; it asks for a straight edge.
• A 3D Line (and a sketch's Text) could not be hidden ("Nothing to hide or show"): Hide / Show, Show All /
  Hide All Sketches and the browser treat them as sketches; a 3D Line a Sweep uses hides, as a used sketch does.
• Midplane between a face and itself was accepted.
• Picks that cannot work (parallel planes, three points in a line, the same point twice) are refused in plain words.

InCad 0.11.3

InCad 0.11.3: test build for macOS (Apple Silicon) and Windows 10 / 11 (x64), FreeCAD 1.1 (tested with 1.1.3).

macOS: InCad-0.11.3-2026-10-25-ac9c1b2-macOS-arm64.zip. Install as before (see README.txt in the archive).

Windows: InCad-0.11.3-2026-10-25-ac9c1b2-Windows-x64.zip, for FreeCAD 1.1 for Windows. Unzip it, quit FreeCAD and run install.bat (uninstall.bat removes it). Send the log (⚙ ▸ Show Log File) with every report.

Both archives have the user manual and the presentation for their system (EN, RU).

0.11.3

Hide Edges works after the Shaded button.

Bug fixes

• Appearance > Hide Edges did nothing once the Shaded button had been used: Shaded drew the edge lines of every Solid
  whatever its setting. Shaded now shows each Solid as it is set, so Hide Edges hides its edges.

InCad 0.11.2

0.11.2

Hole and Thread in several places at once, Apply + keeps the settings, Delete asks about what breaks.

Improvements

• Hole > Concentric: click several round edges or round faces at once (Round) - a hole at the centre of each; the
  Face is optional (the flat face beside them, the one facing you).
• Thread on several faces at once (holes or shafts): a thread on each with the same settings; afterwards each is a
  thread of its own.
• Apply + opens the next dialog with the same settings (only the picks start empty), in every tool.

Bug fixes

• Delete of a feature that others are built on (a Chamfer on a Fillet's edges) hung, then did nothing: it now asks to
  delete those too, as one undo step; No leaves the part as it was.
• Thread in a second hole: the click on it (shown as the first thread's preview) was dropped.

0.11.1

Work Axis fixes: the axis of a cylinder or a cone, marked points for every Point field, the view turns while points are picked; Hide / Show no longer rebuilds the part.

Bug fixes

• Work Axis > Axis of a cylinder on part of a cylinder (a half ring) or on a cone came out across the part: it took
  the face's axis of inertia. It is now the surface's own axis, on a round edge of the face, so it follows the part;
  a face that is not round is refused.
• Every Point field of Work Plane, Work Axis and Work Point (Two points, Parallel to edge through point, Normal to
  plane through point, ...) picked a vertex blind: they now light the part's marked points (corners, edge middles,
  circle centres) as soon as they are active, also right after the Method changes. A corner keeps the feature on it;
  another marked point fixes it where it is now.
• While marked points are shown (Two points, Three points, Section by points) the view turns again with the left
  button; only pan worked.
• Show All Origin (and every Hide / Show) touched the planes and everything built on them: the whole part was
  rebuilt, 10 s on a part with embossed text, and Work Axis lagged after it. A Hide / Show choice now touches nothing,
  and work features recompute only themselves while their dialog is open.

0.11.0

Spur Gears and Worm Gear: a pair of gears in mesh, or a worm and its wheel, in one dialog; they turn together in an assembly.

Improvements

• Spur Gears (3D Model > Create, split button with Worm Gear): one dialog makes a pair of gears in mesh, no sketch -
  Both gears (module, pressure and helix angle, hand), Gear 1 (teeth, width, bore), Gear 2 sized by teeth, ratio or
  centre distance; or One gear. Involute teeth (addendum 1 module, dedendum 1.25). The line under the fields says what
  the numbers make: teeth, pitch diameters, ratio, centre distance. Every number is a parameter.
• Worm Gear: the worm (axial module, 1-6 starts, pitch diameter, length, hand) and its wheel the same way; the worm's
  ends are round (the thread runs out one module before each end).
• Place: an Axis (work axis, sketch line, straight edge), a Center (a circle, a corner or a point) or a Plane; nothing
  picked: a Solid of its own at the origin, beside the gears already there. Mesh with puts gear 1 (or the worm) in mesh
  with a gear already there - a third gear for a pair - and Around it / Around gear 1 turn a gear round its mate.
• Gear 1 carries the assembly's gizmo while the dialog is open and whenever a gear of the set is clicked: arrows slide
  the pair (whole mm), arcs turn or tilt it (5 degrees); gear 2 always stays in mesh. Double-click a gear to change the
  set; deleting the first gear (or the worm) takes the second with it.
• Make Assembly puts each gear into a part file of its own and stands it on its own axis (a Rotational joint to a
  hidden, grounded Gear Axes): drag the gizmo's arc on a gear and the gears in mesh turn with it by their ratio, a worm
  and its wheel too. A part of one piece now makes an assembly of one component (a single gear).
• A long dialog scrolls its fields and keeps OK in sight.

Bug fixes

• Section: gears and worms show their cut whole (the cut through a gear's middle was hollow, a worm's in bits), and
  every shown Solid of the part gets its cut faces, not only the main one.

0.10.0

Hide / Show / Show All, also in the assembly's tree; files made outside InCad edited like InCad parts; an assembly saved into a folder with its parts; a smaller gizmo that goes out; file tabs reachable.

Improvements

• The assembly gizmo is a third smaller and no longer stays on the part: a click on a part shows it for a couple of
  seconds to grab a handle, it stays while a handle is dragged or under the pointer, and then goes out; another click
  shows it again.
• Save an assembly into a folder of its name: Save (first time) or Save As writes Name/Name.FCStd at the place chosen,
  with every part of the assembly (a sub-assembly's too) saved into that folder; the assembly links to the copies, the
  files the parts came from stay as they were. Saving again keeps it all there.
• Hide, Show and Show All said outright (View ▸ Visual Style ▸ Hide / Show and every right-click menu): Hide and Show
  act on the selected solid, assembly part, plane or sketch (a hidden one by its browser row); Show All brings back
  every hidden solid of the part, every hidden part of the assembly, with nothing to pick.
• Files made outside InCad — a script's or FreeCAD's part, a STEP opened as it is — become InCad parts by themselves
  when they come to the front, with every tool: the largest Solid is the main one, a STEP's shapes become Solids where
  they are shown. No Convert button to find.

Bug fixes

• Selecting a part of an assembly lit its whole history in the browser and opened it: only the part's own row lights up
  now.
• A right-click on a part of an assembly picked the object inside the part's own file: that file became the active one
  and opened in a tab of its own, and Hide hid the part there — it vanished from the assembly with no row to bring it
  back. The right-click now picks the part as the assembly's component: Hide and Show act in the assembly's tree, and
  Show on a part's row also brings back a part hidden inside its own file.
• A part whose file was made outside InCad (by a script, in FreeCAD), opened from an assembly with a double-click, Edit
  or Open, opened as "Not an InCad part": no tools in its tab, and a Solid hidden there could not be brought back. It
  now opens as an InCad part (one Solid): the part ribbon, its history in the browser, and Undo or Hide / Show bring
  a hidden Solid back.
• With many files open (an assembly's parts opened one by one) the tabs past the window's edge could not be reached: the
  tab bar now has scroll arrows, long names are cut with …, and the full name shows when the pointer rests on a tab.

What's new in pictures: InCad-whats-new-0.9_en.pdf (English) / InCad-whats-new-0.9_ru.pdf (Russian) — the assembly section of a 20-part engine, a chess pawn from a photo to a coloured part, and every new tool of 0.8 and 0.9.

0.9.0

Section, Interference, Hide / Show and Open in assemblies.

Improvements

• Section in assemblies (View ▸ Visual Style ▸ Section): the cut goes through every shown part the plane meets,
  each cut face in its part's colour with its own hatching angle; Offset, Flip and Section by 3 Points work as in a
  part. It was refused in an assembly. It also cuts STEPs, shapes from other programs and assemblies made in FreeCAD (their Bodies and shapes);
  Interference checks those too.
• Interference (Assembly ▸ Analyze ▸ Interference): where parts go into each other, every overlap in bright red over
  the parts and a panel with each pair and its volume; parts that only touch are no interference; redrawn as parts move.
• Assemblies get Hide / Show too: Show / Hide All Axes (the parts' light centre lines, remembered; a constraint
  dialog still shows them for a pick), Show / Hide All Origin and Show / Hide All Sketches.
• Right-click a part in an assembly ▸ Open: its file in its own window as a part of its own (Inventor's Open);
  Edit still opens it with the assembly around it.
