Gaskets & dimensions coming in wrong

Has anyone encountered this dimensioning issue where an overall includes the gasket graphically but the actual dimension doesnt?

1'9-7/8"
4"
1'4-1/2"
7-3/8"
1/8"
=4'1-7/8" not 4'1-3/4

What does the model have for those actual distances, using precision better than 1/8"?

From memory, ISOGEN works to the closest 1/8" (or 1 millimeter in metric) so there can be inconsistencies from accumulated rounding differences.

In the model to the face of the flange its 4'1-3/4 to the face of the valve its 4'1-7/8"

where are the accumulated rounding/precision settings in I-Config?

ttt still havent got this resolved even with Hexagon's insanely slow support responses lol
