Re: Disable a specific object from recomputing
I had this discussion coming up few times via google, I know it is old, but I think that the point raised by dimitar is still valid. In the current situation I am tweaking a sketch that further down the lines becomes involved in a very expensive 3d offset for a linked object. Every time I close the ...

Re: python 3.10
I am also plagued by python 3.10 on Arch. FreeCAD throws pivy errors on so many operations.
Python 3.9 is available from AUR but I have not find a way to force FreeCAD to use it.

Re: [challenge] fully parametric planetary gear system
At the end I've managed to model directly in FreeCAD, and when needed export to STL or even AMF that was slightly better. Forget the export tool: use the mesh workbench if you want fine control and excellent results. I learnt OpenSCAD as a first step into functional programming and it opened a worl...

Re: Ideas for 3D sweep
Attach your latest file. I am interested in seeing how you used the auxiliary function. I did not save it. But it is very simple: you just select auxiliary and then pick a second path. The two paths work together as the rails of a rollercoaster, fixing the orientation of the train. If the distance ...

Re: Ideas for 3D sweep
I cannot believe it. I have been struggling on this for weeks and it was just that!? Better have a laugh on it
Anyway now, as expecting, I can use auxiliary and sweep on two rails with no wiggles at all:
Great thanks!

Re: Ideas for 3D sweep
Oh, so you are able to use sweep from PartDesign :? Unfortunately I am still plagued by the TopoDS::Wire error, no matter if I try basefeature, shapebinder or drag and dropping the spline into the body. I have even recompiled FreeCAD from the sources and still nothing. I don't understand why. Screen...

Re: Ideas for 3D sweep
... Thank you for your reply. In your screenshot the issue that I have is mitigated. It probably comes from the fact that in your preferences->part design->shape view->angular deviation/deflection you have large values producing rough geometries (and the coloring is also masking the curvature). Wit...

Re: [challenge] fully parametric planetary gear system
If you accept OpenSCAD as a subset of FreeCAD, then I did that a while ago: https://github.com/dpellegr/PolyGear/tree/master/examples https://raw.githubusercontent.com/dpellegr/PolyGear/master/imgs/planetary.gif The bonus is that the gears are done with actual involute profiles, the drawback is that...

Re: Ideas for 3D sweep
To use such paths from outside in PartDesign use a ShapeBinder. I imported the path in the PartDesign by creating a body after having selected the path. The path is imported as a BaseFeature. I have now tried the ShapeBinder as well, but it makes no difference: it still produces the TopoDS::wire er...
