Click the Large Feature
Mode icon 
located along the bottom of
the Hit Target tab in the Probe
Toolbox in the Auto Feature dialog
box for the Line feature.
The Large Feature Mode button is only available with the Automatic Hit Target type.
When you close PC-DMIS, it saves the state of the button. The next time you start PC-DMIS, the button is in the same state ("On" or "Off") as it was in when you last closed PC-DMIS.
Click the Large Feature Mode button to toggle it between the "On" and "Off" states. Each time you toggle the button, a Warning dialog box displays.
You can reset warning messages through the General tab in the Setup Options dialog box. For details, see the "Warnings" topic in the "Setup Options: General tab" chapter in the PC-DMIS Core documentation.

The Hit Target Test icon and the right-click menu are disabled.
