Use the Bridge Section Variation Definition form to review or change the variations defined for bridge spans in the model.
Bridge Object Name display box. This name identifies which bridge object/structure contains the span to which the variation defined on this form applies.
Span Label display box. This name identifies the span to which the variation applies.
Base Bridge Section Property display box. This name identifies the deck section property for the span.
Bridge Section Variation Is Defined By. Choose the appropriate option for defining the variation:
User Definition option and the User Defined Variation For {Deck Section Template} display area. When the User Definition option is chosen, the User Defined Variation For {Deck Section Template} display area lists the type of variation, if any, applied to each of the parameters comprising the section property definition. Click in a cell in the Variation column to display a drop-down list of previously defined parametric variations; select from the drop-down list to change the specified variation. As necessary, click the Define/Show Variations button to display the Define Parametric Variations form and add, modify, or delete a parametric variation definition for the specified span.
Reference to Another Span option and drop-down list. Choose to define the variation based on another span definition by selecting that span label from the drop-down list.
When the Reference to Another Span option is selected, the User Defined Variation For {Deck Section Template} display area does not apply and therefore is blank.
Show Base Section button. Click this button to display the Define Bridge Section Data {Deck Section Template} form. Use the form to review the section definition. Note that when the form is accessed using this button, the parameters on the form cannot be modified.
Show Section Variation button. Click this button to display the Bridge Object Display form. Use the form to review the bridge object.
User Defined Variation For {Bridge Section Type Name}. Choose one of the following options for applying parametric variations:
Distance Measured from Start of Span -- the distance "0" in the parametric variation represents the beginning of the Span.
Distance Measured from Start Abutment - the distance "0" in the parametric variation represents the beginning of the Bridge Object.
For the bridge with skewed supports, option 2 is recommended.
