Comment 4 for bug 255157

    - found out the hard way that this proposal will not run under the official release of Inkscape 0.46 stable. So here is a version custom-made for 0.46 stable. This has been hardcoded to run only the new style of spline, not the old. Before running it, best thing would be to rename the file C:\Program Files\Inkscape\share\extensions\dxf_outlines.py to be something else like dxf_outlines_old.py in case you want to go back to the original version. Then copy these two new files into this same directory. Once this is done, the cutting plotter dxf output should operate the same as before, but hopefully different when you load them into ROBO Master.
    - will post a few sample dxf files shortly, showing the difference between the two styles
    - don't have commit rights, I've submitted one successful patch so far, which was Bug 192923 . Submitted a few proposals for patches, Bug 186432 and Bug 179560 , but they were kind of specialized, designed to suit my own personal interests, and they are sort of in a state of limbo.

 will provide more info in a day or two
