If you select the Meas All Once check box in the Iterative Alignment dialog box (Insert | Alignment | New | Iterative button):
PC-DMIS remeasures all the input features at least once in DCC mode.
The input features are measured in the order specified by the iterative alignment command in the Edit window.
PC-DMIS displays which feature is about to be measured in a message box.
Before accepting the move, ensure that the probe can reach the indicated feature(s) without colliding with the part.
Stored moves found before or after each feature are not executed.
After all the features have been measured at least once, PC-DMIS continues to remeasure the features for measured point types of features and those points that missed their Point Target Radius target (see "Point Target Radius").
Since their location never changes, PC-DMIS only measures circles once while in this mode.
