OpenInventor iv Renderman Interface Bitstream rib OpenCascade ? Drawing eXchange Format dxf and the list goes on. in engineering the two major data types are 2D and 3D. the 3D geometry is used to model and define the intended end result. this is true whether it is a forging, sheetmetal, or a building. this is where formats like iv and rib are good formats like dxf although 3d are better suited for 2D and Drawings. why not make a link between the two? -- Oh i've slipped the surly bonds of DOS and danced the skies on Linux silvered wings. http://pfrostie.freeservers.com/cad-tastrafy/ //www.freelists.org/webpage/cad-linux
