angularity of a constructed 3D plane

I have to construct a center plane between two planes and I get it, that I have to click on dist and construct a 3D plane, then call that my datum (we'll call that datum B) . After I construct the 3D plane, I have an Angularity call out, to the top of the part (we'll call that datum A). I have a MAX Material on the angularity call out also. (Dimensionally from the two planes) . My issue is.... on the CMM print out, its giving me the 'bonus', the correct width for the bonus, but its telling me that the angularity is OUT of tolerance by .100 plus?

Same with the other direct... that I construct dat C and the angularity call out is from A and B datums. Datum C is constructed the same way as datum B... 3D dist.

ALSO... when I look at my "actuals" / hits on the CMM... I do not see how these angularity call out can be OUT .100.

Any help will be appreciated! I'm sure I am missing something simple. Thanks

  • Maybe construct the mid plane from mid points. A constructed mid plane is a perfect plane, so without real boundaries that would used to calculate the angularity. Just a thought.


    Is this indeed a thing? I always though planes have no boundaries no matter how they are constructed... Is there a document we could reference to see how pcdmis handles constructed features (such a as planes) and what to expect from situations like the one you advised?
