How does ArcGIS work to identify gaps in polyline?

How to fill in the gaps in a polyline?
Depending on how accurate the rest of your points need to be, you can simply set the XY Tolerance of the Feature To Polygon tool to 2 or 3 meters. This will fill in your gaps for you, but it will also create polygons whose vertices differ from the original input vertices by 2 to 3 meters.
