### Setting Up the Measure Tool

The Measure Tool has a Width Measure, Height Measure, Circle Measure, Point to Point Measure, Point to Line Measure, and Angle Measure capability. Select the desired capability from the dropdown menu above the tool parameters.

The basic setup flow is as follows.

1. Add a Measure Tool to the image area.

2. Select the desired function from the drop-down menu above the configuration parameter.

3. Adjust the region of interest (ROI) to cover the area where you expect the object to move.

4. Adjust each setting parameter, such as edge selection, edge strength, and image preprocessing, according to the measurement target. Please refer to the Measurement Tools - Configuration Parameters section for details on how to configure.

5. Calibrate if necessary. See the Measurement Calibration for calibration details.

6. Set the tolerance for acceptance criteria. Please refer to the Measurement Tools - Configuration Parameters section for details on how to configure.

Note: The Measure Tool’s Width/Height/Angle Measure capability can be enabled for ROI rotation by clicking the rotation icon at the upper left of the parameters view.

Precautions of Correct Use: When switching between measurement types, the links between tool outputs and GDS tags are lost. This is because the underlying components that make up the Measure Tool are completely removed and then recreated whenever you change the tool’s capability.
