Splines

[jcnewbie]

Can someone explain what is a purpose of spline and what causes it to be created, or why would want a spline ?

I have a circular surface and when I create wireframe I get a spline ? Why can't I get a an ARC ?

I am no expert on CAD, but from my experience a Spline is something that is an Entity that does not conform to standard "Geo metrics", ie. Square(Lines), perfectly round features (Circles/Arcs).

9 times out of 10 when you deal with Surfaces and Mastercam creates Edge Curves, it comes as a Spline.

Sometimes you can convert these Splines to Arcs(Circles).

If you have the "X" family of Mastercam try "Edit" tab, "Simplify" and select your Spline and hit the the Green Check.

If your spline conforms to an Arc or Circle, Mastercam will convert that Entity to an Arc.

Sometimes it works sometimes it doesn't.
