Bridge parametric variation

• The bridge modeler allows parametric variation of non-uniform girder spacing for certain decks, including advanced box girder, precast I girder, precast U girder, and steel girder. Girder spacing is adjusted to fit within the dimension of total width minus overhang distance, regardless of parametric variations specified.

• The bridge modeler allows parametric variation of deck-section reference point in the local X and Y directions. This provides improved control over superstructure eccentricity relative to layout lines at regions of widening.
