Conversion of sh3d files to dwg file format

It might actually not be possible to directly export or convert Sweet Home 3D designs to AutoCAD DWG format, which is what sh3d to dwg conversion represents. Nonetheless Sweet Home 3D supports export to OBJ format (File ► Export) and .obj files are usually well-supported in many CAD/3D modeling tools.
