Bridge Layout Line Data Form

Additional Form:  Shift Bridge Layout Line

Click the Layout > Layout Line > New command to display the Bridge Layout Line Data form. Use that form to define layout lines for the bridge model. Layout lines are reference lines used for defining the horizontal and vertical alignment of the bridge and the vehicle lanes. Layout lines are defined using stations for distance, bearings for horizontal alignment, and grades for vertical alignment. Layout lines may be straight, bent or curved, both horizontally and vertically. Horizontal curves are circular with spirals, if necessary. Vertical curves are parabolic or circular.  The layout lines specify orientation of the bridge relative to the coordinate system. The placement of  bridge objects (e.g., abutments, columns, bents, hinges, spans) is accomplished relative to the layout line.
