# 3.8.7: Line-Line Intersection

This component takes a list of lines as input and mutually tests them for intersection. Output-plug **“IP”** delivers a list of intersection points. **“LSS”** returns all the line-segments including those which result from mutual intersection. There is a one-to-one correspondence between the list of input lines and the data-tree branches with line-segments at **“LSS”**. The input-plug **“LTol”** sets the tolerance length in meter for finding intersections between lines that do not actually intersect. **“LTol”** is also the minimum length of segments at the ends of lines (e.g. at T-intersections).
