Feels like a good fit. If they'd got into the right hands in a uni they'd have been doing the same thing, but my personal sense was they mostly got to CS departments, small volumes went to people with real world 2D and 3D design drive, and when commodity high res scan displays went mass market then CAD bust out and rotring pen shares went south. 

There was this weird dichotomy that architecture schools would have analogue computers because air conditioning engineers used them, but they had to walk to the computer centre to do programming  (this was my experience at Leeds uni  basically)

Vector graphics were sweet-as. People liked pixels better.

More people would have experienced vector scan as asteroids or the tank game that made it into video game parlours but by then 75% plus of the cabinets were raster displays.

The Tektronix 4010 at York was almost always free, people went to the apl decwriter before they'd use it. I really loved it!

Inside DEC they were used (with DEC-20s) to run the Stanford SUDS CAD software.
