This has me curious...being a "old school" cad guy: Pro-E, Unigraphics, Calma DDM, and (at least through v8) of AutoCrayon (AutoCAD) and Rhino always used a Z-up coordinate system. I know a lot of the rendering and animation packages use a Y-up system and apparently now so does SolidWorks? I wouldn't have though they would do that to a CAD solution or is SolidWorks really considered a CAD solution (excuse my ignorance if it's not).

Bizzare.
