Read Hole Callout

Hi,

I am trying to read drawing dimensions to a table. I used workPart.Dimensions.ToArray() method. Linear dimensions fine. However, dimensions that made with "hole callout" have more than one entity in the array. For example, a general hole will have three dimensions in the array (HoleDimension 119341, RadiusDimension 160698, RadiusDimension 160672). Is in NX Open or UG Open a function that bound these dimensions?

Thank you,
