Cross platform, open-source, etc. I haven't tried a recent version, but last time I played with it, it had some funky issues with the CSG algorithm (well - the algo worked ok, but if you wanted to edit the tree - well, the editor had some issues with moving and changing nodes). I'm not a CAD expert though - I was looking at the tool originally because TinkerCAD went away.
I also found this tool - which is kinda like TinkerCAD, but open-source:
Maybe someone could pick it up and flesh it out more?
(note - the "current" version of shapesmith is written in javascript, but there is an older version in his repos that was originally written in Erlang IIRC)

Unfortunately, it's been a dormant project for a couple of years:
