Just to bring this BTTT.
I put this little drawing together during the commercial breaks of the NCSU/Vandy game (which we lost

)
Took me grand total of maybe 15 minutes, and I hit a couple buttons and a plot drawing is generated for me, outlining all the dimensions, measurements and so forth. Now if you tell me that you can't design a beachcat using software like this I'm just going to call you nuts.
15 minutes people and I have an A-Frame, mounts and spring assembly. You want me to animate it?
