WORKXPLORE enables its users to import files from a wide variety of CAD applications. This way, users can work on optimising the model before investing time and resources into creating an actual prototype. A large selection of CAD interfaces is available: Catia V4, Catia V5, Catia V6, NX, Parasolid, CREO, SolidWorks, Solid Edge, Cadds, IGES, STEP, Unisurf, STL (binary and ASCII), WORKNC, VRML, WORKNC tool paths, ISO tool paths, DXF, DWG, HPGL. The program saves the 3D CAD files in a highly compact special format which enables the user to calculate surfaces and volumes, measure thickness, dimensions, angles and much more, without having to access the original CAD files.
