Q: In my part program playback, the points are not being entered for my measurement when I cross the edge or press enter.
A: Confirm in the part view, that the playback target indicator appears as a blinking green dot. After the registration features have been measured for a part, all subsequent measurements require that the current stage position be within some distance of the recorded or nominal feature position for points to be entered. The green indicator indicators you are within the target playback zone.
If you cannot achieve the green blinking indicator, play the part program over again, confirming that the features being measured represent the registration and datum features for your part program.
