Autodesk added the bitmap preview for dwg files and block icon for block definitions to eliminate the need to parse the .dwg file.
Aha, can it be read out? I ever thought, DWG files are binary coded or compressed. How can such a bitmap be read?

The preview bitmap is based on Microsoft's file preview format, and is stored in the same way that other file metadata is stored.
