You can also update Basic hits by probing the part in Online mode or clicking on the CAD in Offline mode with the Measured Hits dialog box open. PC-DMIS automatically updates the dialog box with the new results.
For Basic hits, these check boxes appear:
Use Theoretical
Vector As Approach Vector
This check box allows you to specify whether or not the theoretical vector
should be used as the approach vector. If deselected, PC-DMIS calculates
the approach vector by subtracting the theoretical hit point (X,Y,Z) from
the current probe position.
Learn
Hit During Execution
This check box allows you to specify whether or not PC-DMIS should relearn
the basic hit during measurement routine execution.
