Feature Set to Surface Profile

Hi, I am new to the forum so please be considerate.

When you are creating a feature set and say you put in a circle, a line, and a plane, to create (scn1) when you output (scn1) as a profile Form+Location and MaxMin does this give you the profile of each individual point in those features or a profile of the centroids of those features?

If the centroids, Is there an easier way other than probing all the points over again or probing all the points and then creating your features to get what I am looking for?

Thank you for your help!

Comparing the centroid to the cad depends on the number of hits, so you can't get a accurate comparison... (I guess the cad centroid is calculated from a infinity number of "hits")

average	X	Y
181 hits	31,7930475	31,7930475
91 hits	31,7551237	31,7551237
61 hits	31,7172169	31,7172169
31 hits	31,6035962	31,6035962
16 hits	31,3767761	31,3767761
11 hits	31,1504653	31,1504653
6 hits	30,4739646	30,4739646
3 hits	28,4517797	28,4517797

Thanks, interesting deviations there. That said, if you choose a feature instead of vectors and do a prof of a surface is pcdmis comparing cad centroid to hits centroid or is it comparing where the hits centroid is vs where it should be on the surface?

Thanks

I know this is old but I don't want to re-post unnecessarily.

Can anyone confirm if this still holds true for GeoTol in PC-DMIS 2023.1? As I understand the post here, when evaluating a surface profile, using "features" in a set instead of using individual "points" in a set will evaluate the centroid points instead of all the points along the whole surface?

The geometric tolerance command always grabs the hits from features, as long as they contain hits - certain constructed features (cast, generic etc.) do not contain hits. You can report profile of a constructed set using the geometric tolerance command and it will evaluate all of the hits. You cannot use a constructed set as a datum for the geometric tolerance command.

That's what I was hoping to hear, saving me from selecting all the individual points from each feature to evaluate. Thanks Neil Challinor !
