Functionality
-------------

The node is designed to get the distance between two endless lines (defined by a segment) in space, also provides the point in each line that is closest to the other line and if they intersect.


Inputs / Parameters

+------------------+-------------+----------------------------------------------------------------------+
| Param            | Type        | Description                                                          |
+==================+=============+======================================================================+
| **Verts_Line A** | Vertices    | It will get the first and last vertices's to define the line segment |
+------------------+-------------+----------------------------------------------------------------------+
| **Verts_Line B** | Vertices    | It will get the first and last vertices's to define the line segment |
+------------------+-------------+----------------------------------------------------------------------+

Advanced Parameters
-------------------

In the N-Panel you can use the toggle:
 
* **Tolerance**: Minimal distance to accept is intersecting.
* **Match List**: Define how list with different lengths should be matched. 

Outputs
-------

* **Distance**: Distance between the lines.
* **Intersect**: Returns true if the lines intersect. (Distance < Tolerance)
* **Closest Point A**: Returns the closest point to the line B in the line A
* **Closest Point B**: Returns the closest point to the line A in the line B
* **A in segment**: Returns true if the closest point A is in the provided segment
* **B in segment**: Returns true if the closest point B is in the provided segment
