This example provides a complete measurement routine with comments in the routine that provide explanation. Below the code sample, there are screen captures of the clearance planes. There's also a movie demo of the same program in action.

If you add additional moves or a loadprobe command before a tip change command, PC-DMIS deactivates the pass through plane.
When you make adjustments to commands in your measurement routine, be sure to review the path lines. This allows you to see the effect your changes make without having to run the measurement routine.

Second Clearance Plane - ZPLUS View
Both Clearance Planes - Isometric View
