Hello everyone,
Looking for some ideas about how to find contour lines from intersecting lines set.

Line set for example looks like this :
+----+----------+
|    |     2    |
| 1  +----------+
|    |
+----+


where
|
|
|
is one line, and
|
|
is also one line. From this picture I have 6 lines which are not in any order.

Box 1 and box 2, each made up of 4 line segments, share a common side.

In result what i would like to get is such contour, made up of 6 line segments:
+---------------+
|               |
|    +----------+
|    |
+----+

Maybe someone has some ideas of how to achieve this?

Find line segements that overlap. Erase the portions of them that are part of the overlap. If an entire line segment is overlapped by another, then that entire line segment will be erased.

I see my answer was univoted. Were you looking for something more specific, nestor0424?
