The VPHybridCAD from which VCF drawings originate (not to be confused with VCF contacts) should be exportable to a DWG format right in the program. It seems that CPHybridCAD works with a special variant of DWG thought so it is unclear whenever it can be opened using other standard CAD programs.

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.
