these circles also show up in QCad as well. I would suggest you delete them in QCad before saving the file as .dxf

alternatively, you can delete them directly in Inkscape, in the XML editor, by selecting circles with negative x and deleting them. But the better approach would be to delete them at the source, before saving the dxf file.

There is NO ghosts when I open "case.dxf" from initial post in QCAD 3.4.7.0. (screenshot included)
Also there is NO ghosts in Autocad ( it was used to convert original .dwg to .dxf)
Also there is NO ghost copy in original Inventor 3d model which exports .dwg drawing.

Please recheck what we are talking about.

Also latest dxf_import.py which causes trouble whith inkex.localize() workaround (it will run now under 0.48.4-stable release)
Taken from ticket #1308986

I am using QCad 2.1.3.2, which shows the ghosts.

 with respect to the Python code, I would recommend upgrading to the latest versions of dxf_input.py, inkex.py, simplestyle.py. These can be obtained at:

I think this QCad 2.1.3.2 also suffers from incorrect BLOCK/INSERTS workflow.
All latest software show no evidence of this ghost-copies.

Note: DXF standart in this file is ~R14 (dating year 2000) so it shoud be well-documented. It was very handy when I understood dxf_input source code to provide gcodetools-points import functionality.

Sorry, I have not enough time now to investigate inside this ghost-copy problem...

    sorry to give you a hard time about this, but I just installed QCad 3.4.7, the latest version, on Windows XP, and the appearance is the same as before. Screenshot attached. The ghosts are still present as before, in QCad. It appears that the left side in QCad is an exact mirror image of the right side. Perhaps there is some setting or preference in QCad that could disable this behavior.
    In any event, I believe this should be fixed or edited in QCad, or in AutoCAD, not in Inkscape.
