DWG files fail to parse with 18.2 libs

[johnsmith111155]

Hey there I have some DWG files (AC1021 byte marker at beginning of file) that appear to render fine in AutoCAD that I’m trying to convert to PDFs but they fail to open/parse when I try to open them with the latest 18.2 release of your CAD library for .NET. It’s not all of the DWG files in my collection - just about 40%.
The error I get is something about the file being corrupt or something (which doesn’t seem true).

I can’t share the files and I’m just opening them using the standard CadImage sample code you can find here:

Dwg to pdf convert ImageSaveException
