2D Curve Scan Settings

[[Me...]]

Hey All,

I fairly new to Calypso and scanning,
I Have a Bunch of these Profiles with Unequal tolerance Zone that are giving me a hard time, See Attached
Curious how you would Determine the settings(Speed, Step Width, Filter, Outlier, etc.) while scanning while scanning something like this for best results.

I'm using a Vast XXT Head and Using a 1.5mm Probe.
I currently am using a Speed of 0.118, Step Width of 0.012.
Dimensioning it with Unilateral with Unequal tolerance

Thanks

Hi John,
What problems are you having?

First mistake, which is actually quite common, is that you're using Unilateral. You should be using Bilateral with Unequal Distribution. That should help a bit.

When you create the nominal curve(s) multiply the nominal points by a minimum of 3x. Since
this callout is surface profile, I would (instead of curves) create a freeform surface from faces.
That is if there is enough material thickness.

How to create a freeform surface from face.?

If anyone have materials (pdf.), please share.

Thank you

Look into manuals for your version. In EN it is called "Free form surface" - can be done

• Features -> Special Geometries -> Freeform Surface
• CAD -> Creating features -> tab Points
