I would suggest two improvements. 1) For those who use Draftisight with CNC must often be exported in DXF, can have a more similar to "DXFOUT" in autocad? Now export dxf is slow and cumbersome.

2) to design "artistic" for cnc is very useful to use arcs tangent and continuously. as in autocad ZWCAD etc.Now it is possible using polyline, but it is more uncomfortable

Finally, it would be very useful to a built-in "bounding box" like this http://www.lee-mac.com/lisp/gifs/MinBoundingBox.gif
