(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 you select this check box, PC-DMIS automatically considers each set of probe hits to be a single point measurement and automatically creates an Auto Edge Point. If you do not select the check box, PC-DMIS accumulates probe hits until you press the End key. Only then does PC-DMIS determine the type of feature you measured.
PC-DMIS uses the options as displayed in the Hits, Auto, and Misc areas of the Edge Point dialog box when you create an Edge Point (see the "Creating Auto Features" chapter).
PC-DMIS applies the CAD nominals if you marked the Find Noms check box option.
