I used it to figure out my room arrangement when I first moved in here. I have a part named 'bed', 'desk', 'bookshelf', 'fireplace', etc. Fun stuff.
I too have way too many drive trains CADed...too bad most of them will never be built.
I believe it's nearly impossible to do accurate pneumatics without alot of adjustment unless you CAD each nook and cranny of the system that uses pneumatics.
Though I'm a blasphemist in this thread...I prefer Solidworks
