Add a Clearance Plane

This step adds a clearance plane seven millimeters above the top surface of your part. This helps protect your probe from collisions. During execution, when the probe moves between features, the probe moves up to this clearance plane.

1. Select Edit | Preferences | Parameters to open the Parameter Settings dialog box.

2. Click the Clearance Plane tab.

3. In the Active plane area, set the following items:

• Axis to ZPLUS

• Value to 7

4. Select the Clearance planes active (ON) check box to automatically insert a MOVE/CLEARPLANE command between features you later measure in this tutorial.

5. Click Apply and then OK to close the dialog box. This also inserts a CLEARP command in the Edit window to define the clearance plane.

6. From the Graphic Items toolbar, click the Show Clearance Plane icon () to show the clearance plane as a translucent image. Your clearance plane should look something like this:

7. From the Graphic Items toolbar, click the Show Clearance Plane icon () again to hide the clearance plane. The clearance plane is still there, it's just hidden.

For more information on clearance planes, see the "Parameter Settings: Clearance Plane Tab" topic in the "Setting Your Preferences" chapter of the PC-DMIS Core documentation.
