DeTomaso Mailing List: December 98, Message #148

Dan,
	I looked further into the 3D aspects of AutoCad and found I can only
work with geometric shapes such as a cube or cylinder. This and a few
posts others have sent me have convinced me the task is bigger than the
software I am working with. Sorry I can't be of more help but I'll keep
the thought in mind.
