Used to find empty space between two elements' endpoints.

A gap is not the same as an extended intersection, which occurs when the minimum distance between the endpoint of one element is within the tolerance of another element.

Finding and repairing gaps is essential for creating area topology and linear networks. When endpoint gaps are repaired, the coordinates of all the endpoints within the gap tolerance are modified to have the same value. If there is a coordinate among the set of endpoints that occurs most frequently, it is selected as the new value; otherwise, the average point is used. For example:

The Find Gaps tolerance setting determines if an endpoint is to be fixed or flagged. For example, a tolerance setting of 5.0 would affect an endpoint gap of 4.0, but would not affect a gap of 7.0. For example:
