Shape
Shape objects are used to define the cross section shape of a conduit and a bridge opening. It is also possible to create user-defined cross section shapes.
The shape is selected in the Shape ID field of the conduit or bridge opening Property Sheet. For each conduit / bridge opening, an existing shape or user defined shape can be selected.
Standard shapes
