I have been looking for a solution for hours, but all of them seem to work with lines rather than line segments. The default output is still the distance, however you can also output the vector connecting the two closest points and the coordinates of those points on the lines. To find that distance first find the normal vector of those planes it is the cross product of directional vectors of the given lines.
