Caliper distance

[[To...]]

I'm trying to measure the max and min distance on a plane relative to another plane. I tried using a caliper distance and set the considered feature to Measured Points and the Reference Plane to Outer Tangential. When I go into CAD Evaluation, I see a point indicator on both planes. When I activate tolerance zone, they appear on both planes.

The screenshot below seems to show result of top plane. I really don't understand what is going on.

Any ideas or suggestions?

Bottom line. I'm trying measure the depth of a pocket. I would like to be able show the max and min points relative to the top plane, which is not my Z origin or Spatial feature.

What about using surface profile with reference of only upper plane? Even parallelism will give you some info.

Not sure how well this will work, but, can you construct a perpendicular from your ref plane to the other plane ( OTF then ITF ) and ask for length of perpendicular ?

The only reliable way we have come up with to get the result you are looking for is to:
-Create a new alignment using the reference plane as the primary datum.
-Make a new plane recalling the feature points from the plane to evaluate referencing the new alignment
-Construct Min and Max coordinate feature from the new plane and compare these to the tolerance
