Datum B Profile .01 4 Spots

[[Ky...]]

I have a print that call Datum B Profile .01 Four spots
How do I make Calypso do this I know I pick the spot face . But what else do I use?

If these 4 spots are all on the same plane, I would create a plane, scan all 4 locations in the strategy, and ask for flatness. Profile of a plane with no datum reference would be the same as flatness and Calypso requires datums for profile unless you have freeform I guess.

Looks like the intent is coplanar surfaces. Collect data in all 4 places and drop the plane into a flatness characteristic with the print tolerance.

You could use one plane and make sure the strategy and nominals cover the 4 places or recall feature points from 4 planes into 1.

If you use the profile characteristic you have to compare the feature to itself. Same feature top to bottom with the same fit of Minimum Feature top to bottom. Your result should match the flatness result.

I understand the flatness way you are saying . But the profile I don't quite understand. Thanks for your help bye the way

I see the reference of (.02) Is that stated somewhere else?
Any way I see this as that they can not deviate more than +/-.005 from each other.
They can as a collective float up and down +/-.01 but to each each other no more than the +/-.005.
So one could be at .028 but none can go beyond .018.
That's my opinion.

The intersection points create the alignment,the probing points create the profile.

This is the way to do it. If you have freeform you can do a profile with no datum references. The reason for the profile callout is that its difficult to apply flatness to an interrupted surface and treat it as a single surface. for instance, If the drawing said 4X Flatness .010, it means something completely different. You would actually evaluate each surfaces flatness individually. Y14.5 added the use of profile with no datum references as a way to tie together co planar surfaces. Long story short, like Jason already mentioned it is exactly the same as flatness. All the profile does here is control form over the 4 surfaces.
