Looks like AutoCAD. You can program coordinates to define the drawing in a lot of ways. I only ever used it for 2D drawings but did employ its coordinate system to speed up the process. I’m guessing a real power user could program some interesting models with it.

Linux Mint runs pretty well on 8 gigs of ram on a T460.

They were worth it though. There was one across the street from my high school and I’d play dota, CS 1.6, and StarCraft on LAN with some buddies after school. Nothing beat that experience and it’s a shame we lost something this great.
