When I create a 2D toolpath from from a spline (IGES) I get a faceting effect in the finished cut.

Is there a way to control the size of the facets or make them so small they are not easily visible without changing the splines into true arcs?

When I zoom in on a spline, it is a series of small lines and the G code will come out as X,Y moves rather than a smooth countour.

ThanX

Use the filter settings for the toolpath. That should get you closer to a smooth part. This is assuming you've already posted the file, and that's where the facets are. If it's just in verify, post it and see how it looks, it could be your resolution/video settings.

As REked stated go in to the filter and turn on the out put for arc out puts in the the diffrent plans.

Thanks Reked, cadcam.This wasn't my question but I'm glad I caught that one.
That is smooooth:D
I use Gibbs also and splines are an undesireable condition in that world :cool:

The filter settings will most likly take care of that problem. Right now it sounds like you are cutting point to point where the filter will make arcs instead.

Tighten up your tolerance to get a smoother looking finish.
PEACE:p :p

Thank you everyone!

The toolpath filter did the trick.

It was one of those buttons I overlooked, one of the perils of self teaching.

When using the filter in mastercam, you might want to set a minimum arc radius of like .1" or something like that, and also check your post and make sure your arccheck (if you have one) is set to turn small arc lengths, say smaller than .05 or so (or maybe even a little higher), back to lines. Sometimes with small arc lengths the post will get confused and post the arc in the opposite direction.
