15 years ago i was really good with cad, now its mostly stuff for the cnc plas. i'm really quick and good with soap stone and a floor i havent yet felt the need to computer design. for my work often analog is much more productive. my work is mostly by bid, and if i thought there was a chance cad could be more lucrative i'd be all over it. as it is i hire out allot of cad work on the design/ creative end. the same machine i have with cnc control is an extra $25k, i'm sure its worth it to some people but for me it wont happen.I hear you on simple. For me I don't bend enough to keep it fresh in my head. Bend Tech allows me to draw up a VERY complex part or assembly and quickly build it with no crap tube.
I don't know what it costs now but I have made my $300+ investment back many times over. Caveat would be I am good with drafting, CAD and coordinate systems, I know not everyone is.
