# Edge Distance Tolerance

A LineMax tool fits a line to candidate edge points with respect to a distance tolerance, measured in pixels or the units of the currently selected space.

As you increase the edge distance tolerance, you allow the tool to consider more edge points as inliers and change the location of the found line, as illustrated in the following figure:

In general, set a distance tolerance threshold in client units that is equivalent to a distance of 1-3 pixels.
