Parallel Planes

[[Me...]]

How about plotting the Parallelism characteristic? The form plot should give you the edges of the planes, XYZ coords, and Min/Max coordinates, as well as a good visual of the orientation.

I'm not sure I follow. What "actual" dimensions are you looking for?

You're mixing 2 different things... orientation and location. The parallelism plot will give you the numbers you need to correct the surfaces to make them parallel.

If you want the distances between them then use a Profile characteristic, for example, choose bilateral 2 results and it will give you the Min/Max distance between them relative to each other. Choose 1 of the planes as the feature and the other as all 3 datums.

If not then I'm not following what you're trying to do.

I'll take another shot at it...

It sounds like you want the 2 plates to be coplanar to each other as they lay on a common surface. If that's the case, you can lay them both on the CMM granite side by side. Use the granite surface plane as your spatial and Z origin when you create an alignment. Then you can take individual points on the surface of the plates and report their distance relative to the granite in Z. From those points you can mark up the plates at different locations with +/- tolerances or whatever you need to give to the shop. Or plot the points in CAD Evaluation.

This only accounts for one side of the plates relative to the granite. Whatever side is resting on the granite will be perfectly flat as far as Calypso is concerned.

Just shooting from the hip here trying to help. Hopefully some of this info will be useful.
