layerling 1.89.0

• A narrower shape library holds two columns (#527): A shape library pulled to its own width needed 206 px for each column, so two columns took about 450 px (360 px at the small toolbar size), a little more than the Properties panel beside it. A column now needs 190 px: two columns fit in about 415 px, 32 px less at the default toolbar size, 26 px at the small one, and the names still fit (checked in German, where they are longest). Asked for by @prmod3d.
• A diagnostic strip for devices we cannot try (#524): With diagnose in the address, for example https://layerling.com/?editor=1&diagnose=1, a small box at the top left shows whether the page is still alive (two counters that stop when it hangs), the last touches and clicks with the element they hit, the longest task and the last errors. It is plain DOM, so it still draws when the app is stuck, and it is not there without the switch. For an iPad on which nothing answers any more after two taps.
• The revolve sketch shows the other bodies from the front and puts the body where the profile was drawn (#525): The revolve sketch drew the other bodies of the design as their outline from above (a plate as a flat rectangle), while the profile is a side view with the axis standing upright, so the profile could not be lined up with them; and the height at which it was drawn was dropped, the body always standing with its foot at height 0. On the base plate the other bodies are now projected onto the front view through the origin (width across, height up, the axis at the middle), the part edges too, and the finished body stands where the profile was drawn: the lowest point of the profile is its foot, the horizontal line through the middle is the ground, so a profile above a plate makes a body that stands on it. A body that is edited keeps its place as before, and a sketch on a workplane on a face is unchanged. Asked for by @willi1955 with Tinkercad's revolve sketch as the example.
• The mouse wheel in a number field with Shift on a Mac (#226): With Shift held, a Mac turns the wheel sideways and reports it as such, and the field only listened for the up-and-down turn, so Shift (ten times as much) did nothing there while Ctrl and Alt worked. The field reads the sideways turn too now when Shift is held. Reported by @WagnerBoyzRacing.
• An exported OBJ stands upright in the slicer (#541): STL and 3MF were written with Z up, as slicers expect, but the OBJ with Y up, so Cura and the Creality slicer showed such a part on its side. The OBJ is now written with Z up too, and says so in its header; layerling's own import knows that line and stands the file upright again. OBJ files exported before keep their Y-up header and still read as they did. The message after saving an STL to a file is worded more clearly (reported by @rondlh).
• Fillet and Chamfer: several quick buttons, Horizontal edges, and the window stays open after Apply (#538): A new quick button Horizontal edges picks the edges that lie flat (the rims of the top and the bottom of a box, a flat circle, any ledge between). With Shift, Ctrl or Cmd a click on a quick button adds its edges to the ones picked instead of replacing them, and the buttons whose edges make up the picking light together (Top and Bottom edges both, when those two were clicked). After Apply the tool opens again on the new body (the way it does since #514 after a feature is taken back), with the same kind and size and no edge picked, so that fillets of different sizes follow without opening the tool each time; its button then reads Done and closes it, as do Esc and the cross. Reported by @rondlh.
• The list of features in the Fillet and Chamfer window stays open when one is taken back (#517): Taking a feature back opens the tool again on the restored body (since #514), which builds the window anew, and the list of features shut itself with it, so every further feature meant opening the list again. The list now stays as it was left. Reported by @rondlh.
• History view: open a group and bring back its parts (#540): A group could only be brought back from the History view as a whole. Now select a group and choose Open group (or press E, as in the design): its parts are laid out to look at, and you pick one or more of them (click, Shift and click) and bring them back. Groups inside groups open the same way, the path is shown with a chevron, and Back out closes one level at a time. Contributed by @gogades.
• A pinned shape library opens again at the next start (#505): The pin was remembered in this browser, the panel was not: after closing the app the Shapes panel stayed closed with its pin still set, and only the next click on it showed it again in its place. A pinned panel now opens by itself when the editor starts. Leaving the sketch still closes the sketch's own shape palette; only the start no longer closes anything. Reported by @prmod3d.
• On a phone the designs of the start page come first: On a narrow screen (560 px and less) the saved designs started about 990 px from the top, more than a screen, behind the three big tiles and the backup note, so there was scrolling at every visit. Once there are designs, the three tiles are a short row of three, and the note that the designs live in this browser, with its backup buttons, stands behind the designs; the first design is in the first screen. On wider screens and with no designs yet nothing changes. Asked for by a supporter by mail.
• Changing the height of a turned body keeps its base in place: A body stands on its base (its position is the middle of its bottom face) and is turned about its centre, so a height typed or slid in the Properties panel moved the centre straight up by half the change and not along the body's own up axis; a body turned by 45 degrees slid by 3.5 mm for a change of 10 mm. A pocket on a sloped workplane therefore wandered along the plane when its height was changed. The patch now carries the position that keeps the middle of the base where it was; a patch that sets the position itself and a body that is not turned are left alone, and the same holds for the MCP action layerling_update_object. Reported by @DrJones in the forum.
• iPad: a lost finger no longer locks the editor (#524): The editor counts the fingers on the screen, and from the second finger on the view belongs to the camera and nothing is selected. A finger whose end never arrived, for example because the handle or number it touched vanished when the selection changed, stayed in that count, so every later touch counted as a second finger and nothing answered until the page was reloaded. A new first finger now starts the count afresh, and so does leaving the app and coming back.
• Fillet and Chamfer on a group start faster the second time: A group that holds filleted or chamfered parts is a mesh, and every start of the edge tool turned that mesh back into an exact body by sewing its triangles (about 7 of the 10 seconds measured for a pocket in a filleted body of 3,400 triangles; 21 seconds on the forum member's laptop). The worker now keeps that solid as its BREP, up to four of them, as long as the triangles are the same, so cancelling and starting the tool again, or Undo and Redo, skips the sewing: 3.5 instead of 10 seconds in the same design. The first start takes as long as before; the cure for that would be to keep the exact body with the group, which is a bigger change. Reported by @DrJones in the forum.
• The two-finger zoom of a trackpad works in the sketch too (Safari on a Mac): Safari sends a pinch as a gesture with a scale, not as wheel steps; the 3D window already turned it into a zoom, but the sketch did not refuse it, so the whole page was zoomed instead of the drawing plate. The sketch now zooms under the fingers, at the zoom speed of the settings (at the default one the plate follows the fingers one to one). Asked for by @Jenserer in the forum. Not tried in Safari by us: the gesture was replayed in the browser, the pinch itself cannot be.
• Fillet and Chamfer in the sketch follow the order of the editor (#533): The symbols were the same, but the sketch put the Fillet button before the Chamfer one while the editor puts the Chamfer before the Fillet, so a hand that switched between the two reached for the wrong one. The sketch has the editor's order now, in the toolbar and in the command search. Reported by @AkiraNorthstar.
• Chamfillet in the Chamfer tool (#513, #531): The chamfer window has a choice at the top, Chamfer or Chamfillet. A chamfillet puts a chamfer at the plate on the chosen edges that blends tangentially into a fillet toward the wall, so the first layers need no support and the edge still ends soft; with Bottom edges it takes the whole foot of a part in one click. It is built in the CAD kernel, so the STEP export keeps it exact. The edge tool of the AI connection takes the kind chamfillet, too. The kernel's smooth surface normals now also stay in use for every edge treatment, which makes fillets render smoother. Contributed by @corefile.
• Arabic: the guide pictures from the Arabic interface (#534): The 35 pictures of the Arabic guide are now screenshots of the Arabic interface, the same set as in the other languages. Contributed by @sevagjb.
• Folders for your designs (#496): With dozens of designs the start page had only one list. New folder now makes a folder for the designs of this browser, and folders can hold folders. A design goes into a folder by dragging it onto the folder or with Move to … in its menu, which lists every folder; a new design, and a file opened or imported, made while a folder is open lands in that folder. Inside a folder the first tile, .., and a path under the heading lead back, and take a dropped design or folder as well; a folder dragged onto another goes inside it. A folder's menu renames and deletes it, and deleting a folder deletes no design: what was in it moves one level up, and the dialog says where. The search looks through every folder and shows the folder of each design it finds, as a button that opens it. Back up all writes the designs into their folders in the ZIP (under Folders/, empty folders included), and restoring brings the folders back; designs in older backups land at the top level as before. The folders are kept in this browser beside the list of designs and follow in another open tab. The names follow the rules of the folders on the server. Asked for by @uowmag in #496.
• Japanese: The interface speaks Japanese, all of its sentences, and the guide pages have their Japanese words; the chapters are not translated yet and show in English. It is written for upper primary school children and their teachers, many of whom know Tinkercad: short sentences, plain words instead of hard compounds, and Tinkercad's Japanese terms where Tinkercad has one (デザイン for a design, シェイプ for a shape, エクスポート, ビュー). Words that are English in katakana stay as they are, such as ボディ, ミラー and フィレット, and a sentence names a button or a shape exactly as its label does. The Bricks units read ブロック and 1:1（ポッチ）, words children know.
