My laser and CNC will cut curves and splines fine. I have, however, recieved files from others that upon inspection the line segments were drawn wrong, which makes the cut look wrong. I think it comes down to how you draw it. I had a heck of a time getting sketchup files to work right even exported as a dxf.
Never heard of a CNC not being able to cut a curve or spline, it's all in the G-Code. If you want a curve, draw it as a curve not a bunch of rotated straight line segments.
