Slot Width/Length Bonus?

I've attached a print and code of my program on v3.5MR2.

First question is why is PC-Dmis adding both bonus tolerances, width & length, together to calculate the true position bonus? I'm looking at a old CMM report of v3.7MR3 and it is only using bonus tolerance of the width to calculate the true position bonus...Is this a known problem in v3.5MR2?

Second, I don't fully understand boundary and if it's possible to dimension correctly in v3.5MR2...

Thanks for your help.

I would do a CLOSED SCAN with the scan generated from the cad data. Pretty much, that's what is required. None of the scan can violate the boundary boundaries, whichever why they chose to dimension it, either "bigger" or "smaller" or bi-lateral.

Thanks Matt, so looking at the original print I attached I would do one dimension of the length and width size tolerance. Then perform a linear closed scan to the CAD of the round slot...edge point scan or just a vector scan?

Then dimension that closed scan directly using the "Profile" dimension tool, form and location, with a tolerance of ±0.1. Does that sound like it'll satisfy the print?
