I don't know here is a good place for this question or not but I have a problem with converting tiny lines to polyline.
Tiny lines are not snapped to a common intersection, but are so close to each other that can be considered as a polyline. The problem is small distance between those tiny line's end points.
The main goal is snapping nodes (at ends of lines) within the tolerance distance to a common intersection in order to converting them to a polyline.
First I added all nodes (ends of lines) to an array but searching for the closest point to each line is so slow.
Any suggestion?

Sorry for my poor English, if any.
