We have an issue with our DXF task output where occasionally our sigmanest software can't read the DXF files, it returns an error about non homomgeneous coordinates and our work around has been that we have to re-open the dxf and convert all of the splines to polylines.  When we used to save out our DXF's manually we always saved the DXF's out in the oldest AutoCAD version available and we wouldn't have this issue.  The "Conversion Options" box in the task window is not available when DXF is the selected output in EPDM.

Does anyone have any suggestions? 

Thanks,

Chad
