It would be nice to see a forum that deals with Rapid Prototyping issues. Such as, file formats, model finishing, texturing, both visual and physical. What normals are and how to avoid errors. What software can be used and how to export your models. The list is almost endless, but what I would most like to see is some input from Z Corporation and the experts. Especially 3d topography and DEM files, or getting files from the ArcGIS file system to a 3D solid that is printable.
