What I would recommend is rather than modeling formers and lofting between them to produce the body, instead try making the body as a surface loft and then modeling the formers within that body. If you already have 3D parts generated for the formers or ribs, Auto Layout should be able to get things to a state where you can make the drawing of the part studio and export to DXF. Here's a video I made that features more info about how to use these workflows: Does not do nesting (uses bounding boxes of parts), but saves tons of time flattening things out:Ĭreate drawing -> custom template -> no border or title block -> insert part studio filter -> select your part studio with the layout feature already run -> top view -> export as DXF -> ready to send to laser cutter! Laser Joint - custom feature that automates laser-cut finger joints:Īuto Layout - simple layout tool for 2D cutting. If you're doing laser cutting, here are some useful things to know: Perhaps there are some other workflows that would be even more efficient. What sorts of things are you modeling that require sketch blocks and sketch scaling? For scaling, you can scale a whole part at once with the transform feature, but admittedly, this doesn't work for parts within sketches. Instead of repeating features in sketches, you can write a custom feature or derive components to save on design time. Metalworking is in mm, also with fraction of mm (8.000mm +008, -002).Generally, Onshape approaches modeling differently for 2D objects than 2D CAD packages do. The second obvious one is woodworking, because in europe they tend to think in cm, while in the US still in inch. The most obvious one is architectural work, because it is huge (meter, centimeter) Would be useful to start collecting usecases? However 12900mm not telling me much, when I wanted a 5meter and 7meter length of wall with wall thickness taken into account. So for example if a wall needs to be 5m+7m+3*30cm, then I can put it in the length field, it is converted to 12900mm, and it is displayed it as is. On a slightly related note: It would be tremendously helpful, if you could specify a unit via simple math, and the actual math would be preserved when you modify (displaying the result of course). in sketch) in cm, freecad accepts it, but instantanously converts it to mm (freecad internal unit?), and it is displayed and when you modify it, also shows in mm. For example if you modify a line, then in the Data panel it should also display in cm if that is the preferred unit. I think one would expect to see units displayed everywhere the same. I think the easiest way out would be to allow to specify the desired unit in the Draft dimensions (and having a default in preferences). I tried to read on units in FreeCAD, but it is absolutely not clear, and looks like it is written as a brainstorming for developers. Units below 1 meter is displayed as centimeter: 30cm, 40cm, 15cm (wall thickness for example) Units above 1 meter is displayed as meter: 1.10 m, 1.20 m, 2.88 m Is it possible? In preference I can only change it permanently. I would like to display units in different format then mm. I would like to scale everything permanently. Scaling via the Draft workbench scale utility createsĪ Scale (clone) object in the treeview. So I would like to scale everything by factor of 100. The drawing seems to be 100x smaller, then in real life (length of 20mm corresponds to 2meter). I converted the dwg to dxf file, cleaned up in LibreCAD, and imported into FreeCAD. I'm trying to follow the Arch tutorial here:
