Yes, a Program called Sketchup.... that's what most use <- Recommended Or..Anim8or but its mostly used for 3d animating
Try POVRAY using the Moray modeler. Thats what I use and the results are awsome, but it has a steep learning curve. Bill
Sketchup, however good you find it, is a $475 program with an 8-hour free trial. He asked for freeware. Please keep warez discussion off the forums.
Blender (IIRC they used it on one of the Spiderman films) is freeware. The IU isn't brilliant, but hey, it's free. - H.
