PolyTrans is a high fidelity and accurate 3D data translation, viewing, and model manipulation program that provides complete implementations of the most popular CAD, DCC (animation), and VisSim 3D file formats. PolyTrans is used for any task requiring manipulation, viewing or conversion of 3D models and scenes. Now in its third decade of development, PolyTrans is used by tens of thousands of production studios and professional 3D users to exchange complete 3D scene data between virtually any other 3D software package or file format, such as 3ds Max, Maya, Lightwave, Cinema-4D, Softimage-XSI, ACIS SAT, Autodesk Inventor, BVH, CATIA v4 + v5, COLLADA, DirectX, Electric Image FACT, ESRI, FBX, HOOPS HSF, IGES, Illustrator, JT, NGRAIN 3KO, OpenGL C Code, OpenFlight, Parasolid, PDB, PLY, POV, Pro/Engineer, Quickdraw-3D, Renderman RIB, Rhino, SketchUp, Shockwave-3D, Solid Edge, SolidWorks, STEP, STL, trueSpace, U3D, USGS DEM, VDA-FS, VRML1+2, Viewpoint VET, XAML, X3D, XGL, Wavefront OBJ, and just about every other major 3D file format.
Some features disabled. Every 5th polygon removed during export but imported data can be fully rendered without any demo holes showing up.
