The schemes below show the viewing direction chosen during Segment Arrangement View and depending on fork conditions. The legend of these schemes is as follows:

When the fork junction is at the left side of the Support, the viewing condition is from the fork junction to the secondary branches.
If data contains two forks on either side of the support, then the viewing direction is considered from the fork having the larger diameter to the fork having smaller diameter.
If the above two conditions do not give viewing direction (i.e data contain no fork or both forks have the same diameter), then the viewing direction is considered according to the electrical curve of the first found branch routed through the support.
If secondary branches are not routed through the support, the fork junction is not considered to compute the viewing direction. The other branches routed through the support are not part of the fork junction, the viewing direction follows the curve direction of the first found branch routed through the support.
