I have a profile with only a negative tolerance. How is my measured value positive, but the part is checking outtol=0. is the meas on the report an absolute value? I am exporting everything to measurlink and it is having trouble with the negative tolerance but positive meas.
Consider what the GD&T actually means...
Surf Prof w/in 0.1 unequal zone 0 (meaning that your overall tolerance band for your profile is 0.1 wide but that band is NOT plus/minus 0.05 from part nominal...that "0" is the amount of tolerance allowed to be IN SPACE off of the part. If you're scanning the outside diameter of a post and measuring to this GD&T then that tolerance band would all be on the inside of the material with NO allowance for the deviation going off of the print's basic diameter for that feature.
So theoretically, depending on your alignment and how the software reads the surface you're evaluating, it makes complete sense that all of your deviation would be in one direction.
