I thought I would knock some dust off my drafting skills after a small chat with @captain_aggravated@sh.itjust.works
Seeing this image on the tutorial made me realize, FreeCAD seems to be a Technical Geometry Super-Suite. It makes sense that CAD would grow to include all of these things. But I thought sharing the initial perspective of some one who hasn't looked at this stuff in about 18 years might be interesting.
Granted I'm not actually familiar with most of this stuff, and none of it from the POV of FreeCAD. If this can deliver 10% of what I'm looking at, I'm in for a treat.
The issue with FreeCAD is that all the workarounds (so far) are manual. Other apps may well be doing similar things, but they're doing them behind the scenes and the user doesn't have to (for instance) specifically set up a datum plane offset at the exact same distance as the face you want to sketch on and either manage it by hand or use an integrated spreadsheet to set up and reference variables.
I like what I see coming out of FreeCAD these days, but stuff like that is... umm, a lot.
