Hi okapi, I do want to add a DXF importer in the future.

But file importers can tend to be a rather difficult area of work so it may take a while before I can make that happen though.

In the meantime if your CAD program does not support IGES, probably your best bet would be to use Rhino to read the DXF file and save out as .3dm from there.

Or if you have all lines and no curves, you might see about exporting as a PDF and bring that into MoI.
