I have a sheet metal part, that when exported to DXF, has a random subset of 180 degree circular arcs flipped. I've found a number of references to this problem in the past, each of which has had some kind of fix applied. I don't know if this is exactly a regression or some new problem. The dxf stuff is set to auto-download in the Draft preferences, and has a timestamp of today, 2015-06-06, in my .FreeCAD directory.
Am I doing something wrong, or is there a workaround I can use?
Previous bugs describing a seemingly identical issue all of which are documented as being fixed.
