correct way to setup and check profile tolerance of the part using Laser scan

Align the part according to your datums.

Scan the part.

Apply colormap (CAD needed, tolerance ± half the profile tolerance). Apply deviation flags to your liking.

I have found that this is the easiest way to show non-metrologists the state of the surface profile.

What is your scan setting for different type of surfaces as Casting, we have hard time for laser scan to pick up ?

And also if the part was under cut let's say 0.01"- 0.040" on very small narrow pass, how to adjust the scan pitch setting?

Thanks
