Ive been using Photoshop for close to 8 years now and ive been doing 3D design for about 10.
I currently use Pro-e Wildfire 3, but also use, Catia V4 & V5, Unigraphics NX5, Solidworks 09, and spaceclaim to model in 3D. My job in RL is a Sr Designer for Aerospace.
On the side i model things for fun in 3D and then render them in Hypershot to give them the more realistic feel.

My plans as of right now are to learn 3DS MAX, Maya, & Rhino. or at least one of the 3 this yr.
