What is the best way to convert .sldprt files to .obj format.
Converting SolidWorks Part files directly to Wavefront 3D Object Files (.sldprt to .obj conversion) can be done using one of many CAD tools and designated CAD translation services capable of directly converting .sldprt to .obj.
The SolidWorks tool itself provides an option for converting its own CAD files to .obj format. You will, however, most likely need a special plugin when using some of the earlier software versions.
Alternatively, you can use several third-party CAD/3D modeling programs, which support SolidWorks file types.
A widely-used 3D animation application from Autodesk
3D CAD/CAM tool for product development
A commercial online CAD converter
A 3D CAD translation software
A 2D and 3D CAD construction software
