I am trying to perform a perimeter scan on a rather petite surface whose size is comparable to it deviation in location. In other words, the position of the surface will occasionally vary by a greater distance that the features size. So I am taking many points on the surrounding features and creating a best fit alignment for that small region containing my feature.
My question is does this even matter with a perimeter scan? After the perimeter scan is created, does it use the cad model during execution. If you delete the CAD model from a program with perimeter scans, will the scans still function?
Another question, are perimeter scans reliable/stable? Are they commonly used?
