### Measure Tool

The Measure Tool allows you to perform width or height measurements between two edges. This tool:

- Finds two edges, then measures the distance between them.

- Looks for dark objects on a light background or light objects on a dark background.

- Outputs measurements in pixels.

- Rejects measurements outside the user-defined tolerances.

- Features Image Pre-Processing, which makes it easier for the tool to measure width, height, and angle within an image.

The Measure Tool has a Width Measure, Height Measure, Circle Measure, Point to Point Measure, Point to Line Measure, and Angle Measure capability.

Function | Content | Link for tool parameter
Width Measure | Measure the width. | Width Measure Tool Parameters
Height Measure | Measure the height. | Height Measure Tool Parameters
Circle Measure | Measure the radius of the circle and find its center point. | Circle Measure Tool Parameters
Point to Point Measure | Measure the distance between two points using the output values of other tools. | Point to Point Measure Tool Parameters
Point to Line Measure | Measure the distance between a point and a line using the output values of other tools. | Point to Line Measure Tool Parameters
Angle Measure | Calculate an approximate straight line from the edge points and measure the angle. | Angle Measure Tool Parameters

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.
