Blender v2.82.7

When I try to import some DXF the following error appears:

Traceback (most recent call last):

With some others DXF files it works well. Dont know what it can be.

Thank you!

Of course, the file is the following.

Will confirm for now, but it still needs to be checked if this is actually an error in the DXF (or an issue with the importer).

I can open the file in AutoCAD, although I cannot make sense of the drawing. I can recognize some fence sections, however they are not regular. Is there a screen shot of the expected out put?

I was trying to import this DXF file: https://www.viasit.com/fileadmin/user_upload/Arbeitsplatz/Drumback_Arbeitsplatzstuhl/Downloads/Drumback_450-1002_-_480-1002_DXF.zip
The link is located here: https://www.viasit.com/de/produkte/stuehle/drumback-arbeitsplatzstuhl

The result is an incomplete chair:

Is there a simple workaround for this? What about a simple try-except-block? Or will this result in an other error?

Hi, I could import DXF what you said.
ac_bl.png

  1. Open file on AutoCAD.
  2. Select all.
  3. EXPLODE several times until faces become simply 3D meshes.
  4. Export.

I think there is some trouble at mapping DXF to blender model.

Sorry, I do not own AutoCAD. It is also not available for Linux as I know. I just wanted to add more information to this bug report.
