Re: Cmake Error: could not find VTK configuration file.

Are you building in a separate build directory? If so, just delete the whole thing and make a new one. That will definitely delete the cache :D . That worked. This is a trick that should be in the build documentation but is not. I will fix that now. EDIT: I have added a short new section on resolvi...

Re: Cmake Error: could not find VTK configuration file.

Alas, the freecad-gui cache delete did nothing. Literally nothing - I took file manifests with find(1) before and afterwards to check.

Still stuck.

That sounds good, but I I don't know cmake very well. Can you post a shell command that would nuke all these files?

Re: Cmake Error: could not find VTK configuration file.

I was also having this problem on Pop!_Os 20.10 which is a thin skin over Ubuntu 20.10. Could no longer compile Git head - pulled at about 0315 Eastern time. I tried uninstalling vtk7 and installing vtk9, as recommended upthread. That's not sufficient; you must also install libvtk9-dev. After some m...

Re: How does FreeCAD choose the direction of angle constraints?

I haven't had time to check that the "stable case" doesn't reproduce in the tip verseion, as I needed to do work that pays bills. I can understand removing the "stable case" description if you didn't see matching behavior, but youy really should have left in a warning that the be...

Re: Build from repository fails under Pop!_OS 20

I have followed this up by adding the required step to the build instructions in the wiki, with a comment that it will go away when the packaging is next updated.

[Feature request] Radiobuttons in spreadsheets

I'm designing a drilling jig to support vintage Model M keyboards that may need to be scaled to two different sizes - one for an M101 and another for an M122. It is fully parametrized, but at the moment one needs to poke in the base dimensions by hand, which is error-prone. Excel and other spreadshe...

Paid reverse-engineering gig, 3D scanner required

I'm a fan of vintage Model M buckling-spring keyboards. I've been learning FreeCAD in order to design a custom drilling jig for a restoration procedure often done on them called a "bolt mod". I'd like to have a parametric CAD model of a Model M case good enough to 3d-print or injection-mol...

Re: Dangerous curves

Another dangerous curve: pockets that pocket empty space, because you have to reverse them, because FreeCAD isn't smart enough to default to pocketing into the surface the sketch is placed on rather than going "positive" with respect to global coordinates. FreeCAD is indeed smart enough t...

Re: How does FreeCAD choose the direction of angle constraints?

Two requests for people looking at the code for processing angle constraints, for once you've modified it: 1. Either document the new behavior or leave a note explaining it on this thread so I can do it. 2. Please choose a simple rule. I think "always choose the arc less than 180deg" would...
