Feature Checks
Like Datums, Feature checks are added simply by selecting the check type button and then the associated features. The only major difference is that special attention needs to be given to the Tolerance and Datums assignment text boxes. These settings need to be entered prior to adding the check for them to be applied .
Feature Checks can be added by first setting the selection mode clicking on the CAD face, object, or selecting points in the same was as datums are added. However, it is important to first specify the associated datum(s) and tolerance(s) used by the check. In addition to specifying any individual datums used in the check such as ABC you can also use “ -“ to indicate compound datums such as A-B and use @L or @M to specify the minimum and maximum material conditions respectively. The composite true position check shown.
-
Tolerance = 0.02@M, 0.01@M
-
Datums = AE@MB, A
Double letter datum entry in the Feature Check reference is also supported through the toolkit. To add Feature Checks that reference double letter datums, enter datum letters enclosed with square brackets, such as “[AB]” for single datum.
