Simultaneous Evaluations
Position and Profile checks using a common Datum Reference Frame (DRF) can be evaluated simultaneously if so desired. This evaluation method is a specified method within the ASME standard and can be more true to real life in that it more directly replicates part assembly limitations. However, it is more restrictive, leading to more parts failing, and makes it harder to identify why a single check passed or failed. For this reason, at customer request, SA has not set this as the default evaluation method.
To use a simultaneous evaluation, right-click on one of the feature check in the list, select Inspection> Simultaneous Evaluation. The Initial transform from this selected check will then be applied (which could be a Custom Initial Alignment) and then all of the checks that reference the same DRF will be evaluated simultaneously as a unit.
Once evaluated the check results will then be locked such that each check result can be independently viewed without forcing a re-computation. They will also be marked as such in the Datum and Tolerance Summary Table.
In order to reevaluate these checks the results will need to be cleared by right-clicking on the Feature Check Category in the tree and selecting Clear All Check Results.
