We have found one software suitable in our database for this conversion.
The most convenient way to achieve 3dxml to dwg conversion would be to use CATIA form Dassault Systèmes S.A., which allows users to export Dassault Systems Universal 3D XML file (.3dxml file) to AutoCAD Drawing file format (.dwg file). The overall support for 3DXML format is somewhat limited, so there won't be many alternatives.

3DXML
Files with 3dxml file extension can be found as proprietary 3D CAD files from Dassault Systèmes CAD applications.
DWG
A dwg file extension is used for common 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. It's because of this, that DWGs are often exported to DXF interchange format, so they can be seamlessly used in other CAD programs.
