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&...

Re: Sketcher location bug in body links?

@ppemawm Well, I'll start with the good news, this a3c4f4b introduces the first regression in that it doesn't handle Links ( Report View Error: <Gui> Document.cpp(384): Invalid sub object 'link_sketch_bug#Body_2.Sketch001.Body_003.' ) so in theory that may not be a big deal to fix without introduci...

Re: Assembly 4 workbench--Link Sketch Bug?

Can anyone else confirm? And, should I also report this in the Open Discussion group? I can confirm, and it seems to be a Sketcher bug, not Asm4. When following your example and creating a new sketch, the Sketcher opens in the wrong attachment position, and it's not even possible to draw anything i...

Re: Integrated Assembly Workbench, not the official Thread (Unified Assembly Workbench)

A lot of hate speech against a new Assembly workbench , why? Because it is integrated from zero... ... without even knowing how it works. Or *IF* it works However, there is actually a reason why it had to be included in the built-in modules even though it is not ready: It is coded in c++, and the F...

Re: Assembly4: An Alternative to a Mastersketch for 'Solving' an Assembly--Update #2

Hopefully, with this example and others that I have posted, you are getting the idea of how universal and flexible the Assembly4 LCS joint connector is. Of course, you must be comfortable with a bit of math, variables, expressions, and attachment modes. But, hey, all of FreeCAD is based on these pr...

Re: [BUG?] Adding cosmetic vertices to rotated views does not work properly

Cosmetic vertices on rotated views should be sorted out by 4ffba97 . Thanks a lot! Everything I tested worked in the newest git, so this has definitely been solved in the main branch now.

Re: How to handle message: no exact match for changed 2d reference

This means that stage 1 of the auto correct algo has failed to find a match and you get the no exact match message. Yes, and this is message is quite fair and also sometimes useful. However, the message is yellow and looks like a warning, even though it's not a warning and as far as I understand, i...
