Reversing Alignment Direction

Use this command to reverse the direction and stationing of an alignment.

All objects that are dependent on the alignment (such as profiles) will also be updated.

When you create an alignment, you can control the direction of the alignment, regardless of the direction the polyline was drawn. If you create an alignment using the Create Alignment From Polyline command, the alignment direction starts from the nearest endpoint you click the polyline. If you create an alignment using the Create Alignment By Layout command, the alignment direction is determined by the direction in which you draw the alignment. If you must change the direction of the alignment, you can use the Reverse Alignment Direction command. However, it is important to note that all objects that are dependent on the alignment (Profiles, Sample Lines, Sections, and Corridor objects, Superelevation) will change as well.

You can only change the direction of an alignment that is continuous.

You can also reverse the direction of an individual fixed, unattached alignment sub-entity. See Reversing a Fixed Line or Curve Entity Direction for more information.
