Cross Section Criteria
-
Cross-Section Criteria. In order for a group of measurements to be considered a cross section, they must be within the de- fault 1mm of each other in the cross section direction. In other words if you fit a plane to the data none of the points would be greater than .5mm from the plane. In order to take measure- ments in this format a geometry trigger measurement mode would be easiest. This cross section criteria can be adjusted by selecting GD&T Options under the Analysis tab in the User Options dialog. The number of cross sections used in the analysis is re- ported in the summary table of the check.
