Re: Who can help if not Zolko

We are surprised about the attitude in a forum about free software that we must not discuss such a dramatic decision. It was always said, that Free in FreeCAD means more than free beer. Is this still the case? Was it really necessary to play such a power game between the developers and Zolko? Of co...

Re: Issue #5694 Broken View

This would work for a single break, but when there are multiple breaks on the same shape, each break affects the positions of all the other breaks - a sort of circular dependency. I would think that each break should have their own Sketch in the 3D model (so strictly one break per one sketch, but p...

Re: Issue #5694 Broken View

Suggestion: You could use the actual geometry in the Sketch for making the break line shape. That way, if the user would make the (nicely shaped) break lines for each cut, you'd be able to use the user-made break lines for both the slicing operation and the actual break line drawing by re-using the ...

Re: ASM4 - Yankee_Differential_Cardan - Progress

This is annoyingly similar to what has happened to sketches in links: https://github.com/FreeCAD/FreeCAD/issues/11958 which has yet to be addressed. Indeed, and I think the problem with the Sketches is actually in the PartDesign GUI part of the Sketch handling, so the same problem may very well aff...

Re: [announcement] first version of Toponaming is ready for testing

It now seems to me that the Toponaming merge phase 2 has been completed, and there has been a lot of toponaming work merged to the main branch lately. It seems to me that currently the Toponaming is very active and there's a lot happening at the moment. I don't know for sure, but I'd expect that the...

Re: New 3d CAD based on opencascade & solvespace

What Solvespace as far as I understand it does differently is that the constraint solver also works in 3d there. What comes closest to this are probably the constraint based assembly workbenches. Yes, that could be it. The more correct way for Dune3D author would have been to state it has constrain...

I'll correct myself, as looking at the code it's mostly C++, as one would expect. Somehow, github statistics listed it as 90 % "C", maybe some odd github side effect.

Re: New 3d CAD based on opencascade & solvespace

Very interesting, and it seems to have been mostly coded with C. Could be very useful for simple constructions of 3D-printable objects, for which it's apparently intended. Seems to be a nice, simple, and fast CAD program. That said, I didn't quite understand why the Dune3D developer seems to think t...

Re: Mapping Edges from 3D model to 2D Projections

Going from a 3d edge to the corresponding 2d edge has a partial solution in that you could project the 3d edge and check if the projection overlaps any of the 2d edges. The shortcoming here is that multiple projected edges can overlap a single 2d edge (think of the front and rear faces of a cube. I...

Re: Tech Draw Shifted Lines in Drawing

It would also be good to run the Part workbench geometry check for errors. Activate Part workbench, activate the 3D shape, then menu Part -> Geometry Check and look at the results. Generally, drawings are only reliable on shapes that report zero geometry errors. Please look for "invalid shapes&...
