Section Marker by Chainage

(This functionality is available with the Computations and the Profiles and Design module)

Creates a new section marker by selecting a chainage on the primary alignment.

To obtain this option, select the Create/Section Marker command and the Method/By Chainage command from either the Computations task or the Profiles task when in a plan view to display the relevant dialog box.

The section marker to be created will be given the attributes currently defined via the Attributes/Section marker command from either the Computations task or the Profiles task when in a plan view. You should use these menu commands to set the required attributes before creating any section markers.
