Control system 2-D parts library

FIRST provides schematics for PWM and power distribution. They were created in a 2D CAD program. ( AutoCad I assume ).

Does anyone know where the parts symbol library exists for those drawings ? for those teams that need to recreate the drawing.

edit: it just dawned on me that we could take an Inventor 3D part and flatten it ???

Here are a couple of the schematics from FIRST.
