Bridge Section Variation Definition Form

Access the Bridge Section Variation Definition form, with the Bridge Modeler license enabled, as follows:

Click the Bridge menu > Bridge Objects command, or on the Bridge Wizard select the Bridge Object Definition item and click the Define/Show Bridge Objects button, to display the Define Bridge Objects form. At least a layout line and a bridge deck section must be defined for this command to be available.
Click the Add New Bridge Object button, or highlight a previously defined bridge object in the Bridge Objects area of the form and click the Add Copy of Bridge Object or Modify/Show Bridge Object button, to display the Bridge Object Data form.
Click the Modify/Show Spans button to display the Bridge Object Span Definition form.
In the spreadsheet area, highlight the variation to be reviewed/changed and click the Modify/Show Section Variation Along Selected Span button to display the Bridge Section Variation Definition form.

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.
