## Overriding Found Nominals

FindNoms Override dialog box

The FindNoms Override dialog box (Edit | Override Find Noms) allows you to choose the appropriate nominal point from CAD surfaces for Auto Vector Points, Auto Surface Points, and individual hits inside other features (such as scans). It overrides the default FindNoms behavior of PC-DMIS during Learn mode and Execute mode.

When attempting to find a valid nominal point (within the FindNoms tolerance) by taking a manual hit, PC-DMIS will, most of the time, choose the correct point. However, there are exceptional circumstances when PC-DMIS cannot find an appropriate point and instead chooses an inaccurate point on the CAD model. In these situations, you can use the FindNoms Override dialog box to help PC-DMIS find the appropriate nominal point from the CAD surfaces.

To enable the Override Find Noms menu option, ensure that you have imported a valid CAD model that supports surfaces, select the Surface Mode icon, select the Program mode icon, and then select both the Find Nominals and Point Only Mode check boxes from the SetUp Options dialog box, General tab (Edit | Preferences | Setup).
