Recalculates the orientation of the section lines of the cross profiles connected to a longitudinal profile.

The orientation of a cross profile is calculated according to the bisector given by the angle formed by the adjacent sides of the connection point vertex of the longitudinal profile polyline.

For recalculating it is asked to select the longitudinal profile to identify the cross profiles connected to it.

Note: The cross profiles are realized by projecting the points of the polylines allocated on the section line and for this reason the orientation of the section line of the cross profile is important.
