I was previously using QCad 220.127.116.11 community edition packaged with Ubuntu Hardy Heron (8.04), which inter-operated with our machine shops just fine. Since I have moved to QCad Pro 18.104.22.168, all of our shops can't open or import our files to their CAM systems.
Arcs are not shown in Autocad 2004 - although endpoint and radius information seem to be available, the arc is not drawn on the screen, although full circles and lines are drawn. The OMAX CAM software gives a message about an unhandled setting and refuses to import the DXF file.
Anyone know where the differences lie between QCad community and Pro?
