Description:

 Join LineStrings joins together two or more LineString items into one. The newly-formed LineString item takes on the properties of the dominant selected LineString.

Select two or more LineString items, then select this command, and input a tolerance: this is the maximum distance allowed between the LineString items for them to be joined. LineString items which are further apart than the tolerance will not be joined. You are given the option of creating a new LineString item, keeping the existing LineString items unchanged.

The LineString items are joined by moving vertices so that they are coincident.

Example:

1. Select the LineString items to be joined.
