While doing a measurement in NX between an Edge of a solid body to an Arc Center the user would have to set the Object to Measure to "Object", select the Edge, then return to the dialog and change the Object to Measure to "Point", then select the Arc Center.
It would be easier to use Hotkeys to change to the the different options in the "Object to Measure" section of the Measurement dialog.
This is Enhanced in NX 1980, when the Measure dialog is open, you can now select the number key to select the 6 different Options.
For this example, the User can now select the #1 key for Object and select the Edge, then select the #2 key for Point and select the Arc Center.
The different options are assigned as follows;
1 = Object
2 = Point
3 = Vector
4 = Object Set
5 = Point Set
6 = CSYS
