STEP file importing with splines instead of arcs.

[JB7280]

I have a step file, that when imported into mastercam, is mostly splines and NURBS, rather than arcs or circles.  When I convert these splines to circles, I'm getting very small errors, which is giving me weird toolpaths.  Is there any way to import this file into mastercam to avoid this problem?

 

I'd share the file if I could, but unfortunately, that would put me in some hot water.

There are some model prep functions -> Optomize/Repair Small Faces/Simplify

I believe Optimize fixed it.  THANK YOU!!  I was attempting to curve the edges, then Simplify Spline, and it was creating geometry that was off by just enough, that it would've screwed me in the end I think.
