(This item pertains to the check boxes on the General tab of the Setup Options dialog box. You can open it through the F5 key or through the Edit | Preferences | Setup menu option.)
The Edge Point Only Mode check box controls how PC-DMIS responds to each set of probe hits. In this case, a set is defined as two singular probe hits. The first hit should always be taken on the surface. The second hit should always be taken on the edge. When this check box is selected, PC-DMIS automatically considers each set of probe hits to be a single point measurement and automatically creates an Auto Edge Point. If the check box is not selected, PC-DMIS will accumulate probe hits until you press the END key. Only then will it determine the type of feature just measured.
PC-DMIS uses the options as displayed in the Hits, Auto, and Misc areas of the Edge Point dialog box when creating the Edge Point (see the "Creating Auto Features" chapter).
CAD nominals are applied if the Find Noms option is checked.
