Multiple Find Nominals data sets from single scan?

DomPinchott
For data analysis purposes, I need to discriminate between two alternating surfaces/materials along a single scan path. I would like to scan once in Master mode, then compare that master set of data against the CAD twice, each time referencing a different CAD surface. I know this could be done by scanning the part twice, but I am trying to save time by eliminating extraneous measurement.

The surfaces alternate quite a few times along the scan path, but there is a gap between them, so I am not concerned about misinterpreting data from one surface as the other.

I have attached an example cross section showing the single master scan in red and the individual data sets that I would like to generate in blue and yellow. For some reason, the forum is shrinking the size of the image to be all but invisible. Sorry for that.

  • Thanks for the detailed answer DaSalo. This does help me have a better idea for what does and does not clear a scan's data when editing it. Most importantly, I also know that I can stop searching for a way to do this. Based on how Point Clouds can work finding new nominals for points, I would have thought for sure that there would be a similar way to do this with Sets or another feature.

    Automation is key, as we will be measuring hundreds of parts over the next year and I will not be the only operator. Manual operations are chances for failure and variation. It still feels like there should be an automatic way to do this, but if there is not, then there is not.

    Thanks again.
