Is it possible that DraftSight 1R5.2 just explodes all non compatible AEC objects when saving file to ACAD2000 format that the file size is increasing diametraly (for example from 40MB to 100MB)? All my ACAD2000 files has been originally created in higher autocad version and have non compatible with ACAD2000 AEC objects but when I worked under Autocad 2000 I didn't expirience this kind of issues - just small info about proxy warning.

I have used DS 1R3 version earlier (for file conversion and some small operations which can't be done under Autocad 2000) and didn't expirience this kind of file size issue as well. Can I disable this AEC objects exploding feature in 1R5.2?
