Is there a concept of attaching the exact program used to create a file to the file? Like: I created this 3D model with this #SolveSpace or #FreeCAD version, with these patches applied, I want to do something so I can re-open this exact model with that exact version , without glitches, 5 years later.…

I just discovered that the "prefix group name" option for #FreeCAD VarSet properties was removed a couple months ago. That feature was such a wonderful affordance for reducing typing and now it's gone. I missed the discussion when it was being axed and it makes me very sad. It looks like "I don't like the aesthetics so you shouldn't have it" won the day. ☹

In #FreeCAD, what can I do from the UI and from Python macros to cause all the topological naming links to be recreated in the current shape?
I have a Part Design Body that for which I can mark it to recalculate and then recalculate and it's fine, but if I modify a driving parameter trivially, including by an inconsequential .001mm, suddenly it tells me that I have an invalid edge …

Over the past couple weeks, I've been designing a spool with some particular features in #FreeCAD, encompassing 6 parts to 3d-print. I've been manually re-orienting them when I print them.
Now that it's working, I realized that I could use the FreeCAD Assembly workbench to create a good packing of the parts in the right orientation for printing, saving anyone else who wants to prin…

To replace my lightweight linked dipole antenna for #POTA I am iterating on a #FreeCAD design for a winder that works with wire that shouldn't be bent sharply around the edges of a more typical winder.
This design allows either figure-eight or circular winding with a minimum repea…
