I imagine both Libre and Free are open-sourced and easily modifiable? I haven’t looked into it, but if it’s anything like Rhino there should be a standard way of writing custom plugins that should close the gap on some of those - at least the object naming would be easy.

I’ll look into them though, thanks! BIM software is such a pain in the ass to work with and one of the most expensive design software I know of, I think open sourced projects would be amazing for BIM if they took off like FreeCAD did
