Yeah it's the program they use for Google Earth 3d Models.

Personally I do AutoCAD (A little) and CATIA V5 (Certified) and a little bit of FreeCAD.
Hmm blender is familiar... but I remember not liking it. downloaded 5 different free CAD programs and FreeCAD was the best.

How much was AC3D?

Do you still have to be a student? I graduated already...
