How to Use Bridge Modeler for AutoCAD Civil 3D 2015
Bridge Modeler is a feature of AutoCAD Civil 3D 2015 that allows you to create and edit parametric bridge models based on alignment, profile, and roadway data. You can also generate bridge documentation such as plans, elevations, sections, and quantities.
In this article, we will show you how to use Bridge Modeler for AutoCAD Civil 3D 2015 in four steps:
Create a bridge assembly.
Create a bridge network.
Edit the bridge components.
Generate bridge documentation.
Create a bridge assembly
A bridge assembly is a collection of subassemblies that define the cross-sectional shape and dimensions of the bridge. You can create a bridge assembly from scratch or use an existing one from the tool palette.
To create a bridge assembly from scratch, follow these steps:
On the Home tab, click the Create Design panel and select Assembly.
In the Create Assembly dialog box, enter a name and description for the assembly and click OK.
In the Tool Palettes window, select the Bridge tab and drag and drop the subassemblies you want to use from the palette to the assembly in the drawing area. You can use subassemblies for abutments, piers, girders, decks, barriers, sidewalks, and railings.
Adjust the properties of each subassembly in the Properties window or by using grips and dynamic input.
Save the assembly when you are done.
Create a bridge network
A bridge network is a collection of bridge objects that define the location, alignment, profile, and superstructure of the bridge. You can create a bridge network from an existing alignment or profile or create a new one.
To create a bridge network from an existing alignment or profile, follow these steps:
On the Home tab, click the Create Design panel and select Bridge Network.
In the Create Bridge Network dialog box, select an alignment and a profile from the drop-down lists and click OK.
In the Bridge Network Layout dialog box, enter a name and description for the bridge network and click OK.
In the Bridge Superstructure dialog box, select a bridge assembly from the drop-down list and click OK.
The bridge network is created in the drawing area. You can see the plan view, profile view, and section view of the bridge in separate viewports.
Edit the bridge components
You can edit the bridge components such as abutments, piers, girders, decks, barriers, sidewalks, and railings by using grips, dynamic input, or commands in the ribbon. You can also use tools such as Move, Copy, Rotate, Mirror, Align, Offset, and Array to modify the bridge components.
To edit the bridge components using grips and dynamic input, follow these steps:
Select a bridge component in any viewport. Grips appear on the component.
Hover over a grip to see its function and options. You can use grips to move, rotate, scale, stretch, or flip the component.
Click and drag a grip to modify the component. You can use dynamic input to enter precise values or angles.
Press Enter or Esc to end the grip editing mode.
Generate bridge documentation
You can generate bridge documentation such as plans, elevations,
