The reference is perfectly clear. It explains exactly how a DWG file is constructed and what each section of data is.

I think what you're expecting is a code-chunk where someone has already done it, which while possible, I wouldn't hold my breath for. There are no native controls in .NET that handle .DWG files, which as the reference points out, is a proprietary, undocumanted AutoDesk format that has been laboriously reverse-engineered over many years.

I could say "I JUST want to put this ice-cream sundae on the moon"... but like a lot of things, the devil's in the details.
