CNC plasma cutters are not all alike. What size cutting table, servo or stepper motor drives, does it need CAM conversion to G and M code, high definition, or air plasma cutting are just a few of the difficult decisions when choosing a cnc plasma.

Inkscape may or may not open DXF files from a specific export filter. If the QCad imports it as polylines (intact lines , arcs and curves) then the resulting SVG export would be the same. DXF can be messed up in either the export or the import (or both) Depending on waht CAM program all of th e"broken" nodes may cut just fine. If they are close enough together they get translated as as connected. You have import options in sheetcam where it will attempt to tie nodes together. Inkscape can only deal with the import as it is and SVG will not "heal" a segmented export from another program/ There are som e tools in Inkscape that will let you join a group of nodes and turn it to a curve and then do a node reduction. It can get tedious and if you export it again in DXF you may lose all if the arc again.
