Al,
I haven't used accutrans in a while but if i recall correctly it does file conversion mostly so you should be able to load a dem file and have it spit out a stl for input to whatever pgm you want to use.
I used it last time to do a conversion of Monticello here in Va. to a stl that i then carved.
Other then file conversion what are you trying to do with it?
