How to change Find_Noms Preference for SCANS

derekvegeta
I'm performing a Find_Noms Scan and while executing it, I got the good ol' error asking me to adjust my tolerance. I mistakenly told it to delete the hits that didnt meet the tolerance: How can I undo this? now whenever I run the feature it will delete a *** ton of points.

Furthermore, isn't there a better way to check a profile than Find Noms scans? This seems a silly concept to me, since this makes nominals change slightly between executions AND if you have a thin feature you're scanning I don't understand how you can account for ACTUAL deviation in the tolerance without risking piercing the wrong surface.

  • Support recommended the use of "Only Selected" for me: anyone use this feature? The help page describes it "When you execute a scan in your measurement routine, and you are searching for the nominal values for the scan's measured points, you can use the Only Selected check box to have PC-DMIS only look for the nominals on the currently selected set of surfaces." which sounds like it's what I'm looking for if I am to stick with Find_Noms

    I always use that. You 100% have to if you are working thin parts, otherwise, WHICH side of the part will it select? If the part is 1mm thick and off by more than 1mm, you'll get BAD data.

    check your cut plane, if you want them all at the same Z, then the cut plane MUST be 0,0,1, as well as the 1, D, 2 points have to have the same Z value. For the other, check the vectors of the surfaces, if some go one way and some the other, then it won't find noms.
