As mentioned in the "After Choosing the Best Nominal Point" topic, PC-DMIS displays the FindNoms Override dialog box in execute mode upon meeting the following conditions:
You must import a solid model with surfaces and select the Surface Mode icon from the Graphics Modes toolbar.
You must select the Find Nominals During Execution check box from the General tab of the Setup Options dialog box.
The Auto Vector Point or Auto Surface Point must have a valid nominal point found in Learn mode (see "Using the FindNoms Override Dialog Box in Learn mode:").
Execution must take place in Manual mode.
PC-DMIS must execute the Auto Vector Point or Auto Surface Point feature.
PC-DMIS must fail to find a nominal point for executed Auto Vector Point or Auto Surface Point.
Once the dialog box appears, execution stops and you can interact with the dialog box in ways already discussed in the "Using the FindNoms Override Dialog Box in Learn mode:" topic.
You can also choose to re-execute the recently measured point feature. In that case, PC-DMIS re-executes and attempts to find nominal values again. If it still can't find any nominal values for the point, PC-DMIS again displays the FindNoms Override dialog box.
You can then do one of the following:
Re-execute again.
Use the Override button as discussed in the "Procedure 4: Choosing a Nominal Point Later" topic
Close the dialog box by clicking the Cancel button. If you close without choosing an appropriate nominal, PC-DMIS replaces the measured data with the previous nominal values.
