Question:

How do I define the start station for horizontal geometry in OpenRoads?

Answer:

The Start Station command in Tasks>Civil Tools>Horizontal Geometry assigns stationing to an element. The command allows you to assign a station value and a position along the element for that station value. This command can be used on a civil element or a plain MicroStation graphic. If this command is never run, then the beginning stationing is assumed to be zero.
