vwf to dwg conversion is usually searched by visitors that own .vwf file from a software called CADVANCE and would like to export or convert the design / model to standard DWG format.
Unfortunately, this is only doable with the original software and no 3rd party software otherwise supports .vmf files. While there is a free viewer available for .vmf files, it does not offer any export or print capabilities.
To make things a bit worse, judging by their website, CADVANCE is no longer actively developed and with only limited support (by phone).
