How i can save my bin files in dwg?

[Anonymous]

Hello! How can I store a file, for example, in the bin format in a dwg drawing? Or associate the file with the object (and perhaps store this file in the object)? Thanks a lot!

Here are some suggestions to try:

1. Via OLE using an AcDbOle2Frame.  AcDbOle2Frame is derived from AcDbEntity.
   Looks like you have to create a COleClientItem (MFC class) and call 
   AcDbOle2Frame::setOleClientItem(oleItem).
2. Using an AcDbXRecord. You must break your binary data into resbufs that contain up to 127-byte chunks.
   Probably the easiest solution.
3. Using a custom object. Derive your own class from AcDbObject and implement dwgInFields()
   and dwgOutFields().
   

I never tried any of these ways myself to store binary data. But I think #2 would be my first choice to try.

Keep in mind, when an outside agency finds "mystery data" (encrypted, binary, or otherwise not easily readable) in a drawing file they may strip it out if not reject the file altogether.
