I think this is one of the things that makes or breaks the usability of CAD
software.

I was able to design library parts for a number of Gxxx, Mxxx, and Wxxx DEC
modules (needed for the TC08 dectape controller) in just a little over a day
with the Eagle CAD software. These parts need very elaborate symbol views
(essentially logic diagrams, needed to make the schematics that use them
readable).
