I haven't heard of Maya ... what's the info on it?
I've done foundation details on Acad, as well as steel detailing, grounding and conduit layouts (kind of like piping diagrams, Steel erection drawings and our electricals. The electricals I do aren't the one-line diagrams, these are the drawings of all the electrical parts put together on the steel structures to show the substation ... closer to a cross between mechanical and architectural. We were doing those in 3D but through Acad which meant we've been dealing with wireframes and 3D facsimilies. With the Inventor, we're actually dealing with objects instead of lines and vectors. It's a whole new world for me and I'm loving it.
I'll have to google the Maya. I've heard of Solidworks and Vectorworks.
