Offsetting curves

[PeterM]

I've noticed this a few times so I thought I'd tossi it out and see what I catch. When I need to offset a curve, the resulting curve is mich more jagged than the original, I have my curve tolerance set to .0002 but that dosen't seem to help. Is there some other setting that I need to modify, or is this a bug?

Have you tried regenerating the screen?

P.S version x on that curve issue.

Just tried that, didn't help

Offsetting it as in collapsing the curve I assume?

 

Not sure how'd you get around that. The curve is controlled by nodes so when you collapse it some nodes have nowhere to go. So it can get ugly.

 

May end up just cleaning the curve up afterwards.

if your setting is corners none spline may be rather different

Corners

The options in this section of the dialog box determine how Mastercam handles gaps that result when you offset a chain of curves outward, making it bigger.

Note: When you offset the boundary inward, the system trims the boundary at corners.

None (Corners) extends the curves until they connect when offsetting the boundary outward.

 

Sharp (Corners) creates arcs at sharp corners to connect the curves when offsetting the boundary outward. A sharp corner has 135 degrees or less.

All (Corners) creates arcs at all corners to connect the curves when offsetting the boundary outward.

Just for S and G I just offset larger and I get the same result. Perhaps this is just the way it is with curves. I have noticed this in earlier versions too, but never asked about it.

Just read WTP's reply, I'll check that out and post my results.

Perhaps a little help in finding a corners section of a dialog box would be helpful.

it is on the contour pop up under the orange direction arrows

Hey! Did you see where I put my glasses? The all option gave me the best results, Thanks. Peter

You are welcome !
