Summary

Description

PowerINSPECT calculates the point as shown in the example below and projects the probe centre to a reference plane.

Note: If the reference plane is further from the probe centre than the probe radius (h>?), then PowerINSPECT cannot calculate the diameter of the circle, and its Nominal value is not updated.

Follow the steps below to create a Single Point Circle element to measure the centre of a hole:

1. On the Geometric Element toolbar click on to display the Points Toolbar.
   
2. Click on the button to display the following dialog box:
   

   

3. Type a name for the point in the Name box, or leave the default that PowerINSPECT provides.
   
4. Select the plane to which you want to project the point using the Reference Plane 1 list box.

   Click on this box to display a list of planes from existing geometric elements that you can use to construct the new point. To select the plane to which you want to project the probe centre, click on its name.
   
   Alternatively, you can select the reference plane using the mouse icon to the right,.

5. The Centre and Diameter areas describe the nominal values for the point. These values are entered when you probe the hole, and can be used if you re-probe the element.
   
6. Click on the OK button to close this dialog box and display the One Point Inspection dialog box.
   
   
   
7. Probe the hole whose centre you want to find, using a stylus whose diameter is greater than the diameter of the hole, then click on the OK button

PowerINSPECT creates two new points:

• A single point circle by projecting the point you probe to the reference plane
  
• A point at the actual position of the probe centre when you trigger the probe. Important: Do not use this point to construct other geometric elements. It is for your information only.
