I am trying to report the parallelism of 3 planes. I have 2 of them set up as different datums. When I try to report out the third plane to the 2 datums, it tells me that the 2 datums are parallel. Am I doing something wrong or will I need to create a single plane from the 2 datums then report it as another datum?

The Datums A and D are called out on the other side of the part and they are parallel. The GD&T callout box allowed up to 3 datums. I know this is the normal procedure for GD&T, but I didn't think you would want to use a perpendicular plane. I just wanted to make sure that I wasn't missing something before I went ahead and created a new plane from the 2 datum planes.I Work In Quality not Quantity

I would create a symmetry (mid) plane between a and d and report the parallelism from that... and perp to a, and d and see what the difference is in the three measurements
remember parallelism is calculated over a distance... typically the points used to gather the planes... if you want to calculate it over any other value you must input that value in the perp dimension box
