Arc Edge Locator
The Arc Edge Locator tool identifies and measures the position of one or more edges on a cir-
cular object. Edges can occur in a radial or an annular position.
The Arc Edge Locator uses pixel grey-level values within the region of interest to build pro-
jections needed for edge detection.
After the Arc Edge Locator detects potential edges, it determines which edge pairs are valid
by applying the constraints that are configured for each edge pair.
The Arc Edge Locator determines the position of one or more edges, but it does not measure
the length of lines detected in the region of interest. To extrapolate and measure a line on an
object, use the Edge Finder tool.
