Import Error

Import Error "Unsupported DWG/DXF File Version"

GEt this message when i am trying to open an AUTOCAD file .
Is it related to the AUTOCAD Version?
Request help
Thank you in advance

As the message says, the file version is not supported.
Try to save the file in AutoCAD with an older DXF/DWG version, 2017 or older.
If you don't have AutoCAD, request an older version from the drawing author or you have to find a converter.

tried conversion also LordOfBikes - error dissappeared but i cannot get to open the .dxf or .dwg file ; LIBRACAD just hangs with "Not responding" error
i guess i am too much of a learner
