Huge circles or arcs.

[wwwmthboardscom]

So what Im trying to do is make a rocker table in wood, what happens when I cut huge circles or arcs is they cut strait line like a hexigon. I know in cnc everything is a strait line or step in xyz. Small circles are fine in turbo cad.
I guess if you draw a circle in turbo cad and zoom in you will see its just strait lines to make that circle, how do I change that Im making something thats 66 inches long. Thanks.

This post has been here for a while and I hope you have already found a solution. I wonder if you could either node edit the arc to divide it into smaller portions. The easier way to accomplish the same thing would be to explode the arc several times to break up the arc. I have not tried this with anything I cut, but it might smooth out your lines.
