It seems that conversion from VRML graphics (.vrml, .wrl) to a DWG format is possible with some dedicated CAD translation programs. However, this will create a 2D CAD drawing from a 3D model. Some good software choices for this CAD conversion are listed below.

The table with program actions contains information about what each program is capable of doing with their files. This may be a good pointer for further searches for certain file conversions and help you find the converter you are looking for if our search result is insufficient for you. However, it is far from perfect and may sometimes show results which are not really usable because of the nature of the software handles the files. So a conversion that appears as possible, just because of matched actions, may in fact not be possible.
