# Edge Fixture

The Edge Fixture tool allows you to locate a single edge or line, and uses it to construct a fixture. The mid-point of the line provides the X and Y location of the fixture, and the line angle provides the fixture angle.

To use the Edge Fixture tool:

1. Open the Inspect tool palette, expand the Locate tool group, and select the Edge Fixture tool.

2. Select an edge. The selected edge is indicated with purple.

3. Click OK.

The tool creates a fixture from the selected edge.

To adjust the edge settings:

Use the Polarity setting to change the direction of edge finding between dark and light areas. The available options are black-to-white, white-to-black, and either. By default, the Polarity is set to either.

Adjust the Accept Threshold to change the amount of accordance needed for a passing result using the slider or by providing the numerical value in the Accept Threshold box. Lower the threshold to accept weaker edges or raise the threshold to accept only stronger edges.
