Proper error message for DXF versions below AC1009. Users get notified that DXF files with version below AC1009 (DXF12) are not supported. This is because there is not enough documentation available for those versions. Users with files that old are kindly requested to export their projects to newer versions. In some cases it might also work to just replace AC1006 (or anything below AC1009) with AC1009 directly in the DXF.
