dwg format & specifications

Is there a way to use directly and effectively ".dwg" in Programs (VB
programs) ?
I try cadsofttools DLL, but some bloc infos were missing.
I 'm looking for dwg binarie spécifications to create my own extraction
prg. if someone have this around.

And last thing, do you know a good (freeware if possible) dwg -> dxf
converter that use command lines ? (in case my dwg stuff dont work)

Thanks

 

Not as far as Autodesk is concerned. They guard their DWG file format
very closely. Fortunately, there is another way. Check out the Open
Design Alliance -> http://www.opendwg.org

I believe the R13,R14, and R2000 DWG specifications are available to
guests, while the current DWG format is only available to members.

Look for DWGConvert at the same website as above, specifically this
page: http://www.opendesign.com/downloads/guest.htm

Thanks a lot, great link.
The dwgconverter works perfectly.
The registration procedure is a bit intrusive IMO, and not very practical.
