How to convert c4d to skp. Available c4d to skp converters.
The most obvious choice for a c4d to skp conversion is to use the original CINEMA 4D software. That should allow you to export .c4d files to formats compatible with SketchUp. If you don't have access to CINEMA 4D, you will have to rely on some third-party alternatives and specialized converters, such as Okino PolyTrans.
