I've been in construction for over 40 yrs. GC since 1982.  I've been doing mechanical /architectural drawings since HS....Starting using CAD when AutoCad was first introduced and still using it...Except for hand lettering & drawing, it's been all cad. 2D & 3D.  I've bee using Chief since the early versions. Unfortunately lost my status, friends in the forum when CA changed the format..
