Oooooooh, no Solid Edge, I detest it! I use Solid Works, mostly because it's simple and has been adopted by industry rather well. Built in CFD and FEM is a nice bonus too..
Why solid edge?
Inventor slows right down. Then again the computer I'm using isn't the greatest. But I've got to live with it. Draw a little bit of everything. Scrubbers, Flash Dryers, Dust Extraction.
And here I thought Inventor was designed to slow computers down.. What do you do for a living? And what are you designing that Inventor doesn't like?
