Re: PCB from kicad_step_up to techdraw. The drawing is being done too slowly or the program freezes.

Which version of FreeCAD? For such demanding TD drawing (demanding because of the etched letter geometry) I'd recommend FreeCAD v0.22 daily. Also, a good strategy would be: Throw all your geometry into a "Part" container, then select the Part container and from Part Workbench select from m...

Re: [Core Bug?] Surface.intersect() sometimes fails with parabolic surface

Just in case, I updated my FreeCAD to the latest Git HEAD, but the problem still seems to persist with the newest build. OS: Debian GNU/Linux trixie/sid (KDE/plasma) Word size of FreeCAD: 64-bit Version: 0.22.0dev.34982 (Git) Build type: Release Branch: master Hash: 55639df57325290e5a9d98ef48d6e1789...

Re: Optics Workbench

Thank you for digging deeply in the code and for showing a workaround for this problem. No problem, and thank you for the excellent workbench! I also opened a thread in the developers forum with a simplified example, and I'm hoping that it'll shed some extra "light" to the problem. :D htt...

[Core Bug?] Surface.intersect() sometimes fails with parabolic surface

Hi! There may be a core function bug with Surface.intersect() when parabolic surfaces are involved. I wrote a short macro to show the problem. Running the macro creates a new document with a body with a parabolic surface, and then creates a few wires and finds the intersection points with Surface.in...

Re: Optics Workbench

The example parabola was already extruded. Please use the link below, also the link corrected to the original post. Digging even deeper I found out that indeed this is not an Optics Workbench problem, but you have most likely instead found a bug in FreeCAD core/OCCT. Congratulations! :lol: The prob...

Re: Assembly4 vs Onshape

Thanks for the example! It's very well done, works nicely, and is simple enough to study easily. It'd be perfect teaching material for Asm4 workbench! :D Also, using conditional tertiary expression for the calculations is really clever, I never thought that one would be able to use those for express...

Re: [WIP] vertex to line dimension: projected length

@aapo I only modified the vertex to line distance so 1. For edge length select the edge (or the 2 vertexes) and create the distance 2. and 3. select one vertex or the other and their opposite line and create the distance. Great, this should work splendidly, then. Thanks for doing it, let's hope it ...

Re: ASM4 workflow for complex variable assemblies

If anyone knows how to get around this circular reference problem (I even don't really understand why there is a circular reference in the first place) please let me know. Atm I think of using an external spreadsheet or a macro for that, but it would make things more complicated. Basically, the pro...
