NXOpen Tolerance Extraction

[vinaykeerthi]

Hi,
I'm writing an NXOpen script to extract the dimensions and the zones from a drawing file into an Excel spreadsheet using VB. However, I'm facing problems with the tolerances.

Specifically, when I am extracting unilateral tolerances using annotations.dimension.UpperMetricToleranceValue, I am getting a default value of -0.1 wherever there is no tolerance. Same follows for the lower unilateral case with LowerMetricToleranceValue. The size which is 0, is returning a value of -0.1.

Can someone help me with this?

Hi,
+0.1 and -0.1 are the default tolerance values for the dimension builder. For example When you create the dimension if you choose the unilateralAbove dimension then it won't allow you to edit the lower tolerance values. But in the dimension object it won't to be reset to 0.

The solution for this, Get the tolerance values as per the tolerance type.
If dimension tolerance type is UnilateralAbove then don't get the lower tolerance values..

If you feel this is a bug then raise in GTAC.

Thanks,

Oh! I see. Figured that there had to be some defaults somewhere. Thanks a lot! I opted to get the tolerances based on ToleranceType instead.
