i whould like to read dwg file using and then draw it in my application.
do you know complete format of dwg file ( header ,start , data and etc) for read stream of its bits or Bytes ?

i found api and dll that thay read and edit dwg but thay are expenciev. i try write my code.

excuse me for my english.

I would look into the Autodesk Developer Network and the DWG and the product RealDWG. RealDWG is the real DWG format libraries to use for an application and not a reverse engineered knockoff.

You should also check out Kean's blog as he is an Autodesk developer expert.

Best Regards,
