Exception "Unsupported object type" while converting DXF to PNG (C#)

I’m having trouble getting certain DXFs to convert to PNG. If I remove specific sections of the drawing and re-run the conversion I can get the file to convert.

Are you able to convert the original DXF? Is there an unsupported object type in this drawing?

I have worked with the DXF file shared and have been able to observe the issue. An issue with ID CADNET-772 has been created in our issue tracking system to further investigate and resolve the issue. This thread has been linked with the issue so that you may be automatically notified once the issue will be fixed.

No rush, just bumping for interest… thanks.


We are working on this issue and will share good news with you soon.

I never received an update for CADNET-772 and I see it is marked closed. Are you able to convert my attached DXF files in CAD 19.9?


The issue has been marked as resolved in Aspose.CAD for .NET 19.11. We will share the good news with you as soon as the product will be shared online.

The issues you have found earlier (filed as CADNET-772) have been fixed in this update.
