We have found 2 software records in our database eligible for .c4d to .dwg file format conversion.
c4d to dwg conversion represents export of CINEMA 4D graphics (.c4d) to AutoCAD DWG format (.dwg), either for 2D or 3D purposes. If you have access to CINEMA 4D, you might be able to convert c4d to dwg by first exporting the to DXF and then using any of the available dxf to dwg converters.
Without CINEMA 4D you will have to rely on some 3rd party c4d to dwg conversion, for example PolyTrans-for-CINEMA-4D.
C4D
Files with c4d extension can be most often encountered as 3D model files created with professional 3D modeling software tool CINEMA 4D from MAXON.
DWG
A dwg file extension is used for standard CAD file format, originally used by AutoCAD. A DWG is a proprietary format and can only be created in AutoCAD. Other CAD programs can usually import it but not create its proprietary form. Because of this, DWGs are often exported to DXF interchange format so that they can be seamlessly used in other CAD programs.
