Is there a way to save or export ovals with AutoCAD that will cut as true arcs instead of a bunch of line segments? I have cut circles using those little lines and they do not come out very nice. I can sand the little bumps down if I must, but I prefer them to cut as true arcs in the first place.

I'm using LazyCAM 2.0 to convert the dxf to gcode.

Thanks!

If you mean ellipses, then type PELLIPSE and change the value to 1 before drawing the ellipse. It will now be made up of arcs.

It will deviate slightly from a true ellipse, though, because you can't draw a true ellipse with arcs.

As long as it's better than what I can do by hand.

Thanks, I'll give that a try.
