Circle

The Circle tool provides measurements that find the best-fitted circle to a profile and measure various characteristics of the circle.

The tool may be unable to fit a circle to the profile when attempting the fit on a small number of relatively collinear data points.

For information on adding, managing, and removing tools and measurements, as well as detailed descriptions of settings common to most tools, see Tools Panel.

Parameters
Parameter Description

Source

The sensor, or combination of sensors, that provides data for the tool's measurements. For more information, see Source.

Stream

The data that the tool will apply measurements to.

This setting is only displayed when data from another tool is available as input for this tool.

Region

The region to which the tool's measurements will apply. For more information, see Regions.

Filters

The filters that are applied to measurement values before they are output. For more information, see Filters.

Decision

The Max and Min settings define the range that determines whether the measurement tool sends a pass or fail decision to the output. For more information, see Decisions.
Anchoring
Anchor Description

X or Z

Lets you choose the X or Z measurement of another tool to use as a positional anchor for this tool.

A measurement must be enabled in the other tool for it to be available as an anchor. The anchor measurement should also be properly configured before using it as an anchor.

For more information on anchoring, see Measurement Anchoring.
