Slot Width/Length Bonus?

blind829
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.

    "The position boundary specification locates the feature to the datum reference frame.
    No portion of the surface may be permited to lie within the boundary of MMC contour
    minus the position tolerance when position with respect to the DRF established by datum
    features A,B at MMC, and C at MMC."
