Click the Measure button from the Main toolbar.
Select the Measure Circle button from the QuickStart window. The QuickStart circle interface appears. If no Reference Plane exists at this point, you will need to measure it. See "Measuring a Reference Plane".
Select the circle's Reference Plane from the drop-down list, or click "New Plane" button to create a new reference plane.
Using the Take Hit (right) button of your Multi Gage arm, take at least three hits to define the circle feature. Hits should be taken so they are uniformly distributed around the circumference of the circle. As the hits are received Multi Gage updates the number of hits. When the minimum number of hits have been received, the nominal and dimension results for the circle are updated in the Status window.
Note: If you are not satisfied with a hit, you can remove it by clicking the Remove Hit button. You can also hold the Done (middle) button for more than one second to remove the last hit.
Note: You may take more hits than the specified minimum. For example 5/3 would display if you took 5 hits where you only need 3. This allows you to further define the circle's geometry. When dimensioning roundness of a circle, it is recommended to take many hits to accurately define the circle's form.
Edit the circle's parameters if needed. See "Editing Circle Parameters".
Click Finish or press the Done (middle) button on your Multi Gage arm. The new circle feature is added to the History window. The Feature ID text in the History window is colored to indicate whether the feature is in tolerance (GREEN) or out of tolerance (RED).
Select the check box next to the new measured circle in the History window to toggle the display of the circle in the report. A measured circle includes evaluation of the Roundness and Diameter dimensions. A circle may also be evaluated in terms of True Position.
