After choosing the best nominal point, PC-DMIS will remember the chosen surface for that feature.
During execution in manual mode, PC-DMIS will:
Use the tolerance value held in the FindNoms During Execution box, available on the General tab of the Setup Options dialog box (Edit | Preferences | Setup). You must select the Find Nominals During Execution check box (also available on the General tab) for this to work.
Attempt to use the same surface and CAD operation (Pierce Point or Drop Point operation) to find the new nominals for the recently executed point.
If it cannot find a nominal point on that CAD surface, it will again access the FindNoms Override dialog box. See the "Using FindNoms Override in Execute Mode:" topic for execution time behavior.
