I noted when I opened up a DXF file created by autocad, some of the arcs were 180 degrees off. It turned out the extrusion vector for these arcs was 0,0,-1 (as opposed to 0,0,1). I was temped to modify the software to handle this more gracefully by simply accounting for the extrusion vector when reading the arc angles. I was curious as to whether or not there were plans to make librecad work in 3D, in which case a more graceful solution than what I am proposing would be needed.
