About Using Styles to Display AutoCAD Civil 3D Alignment and Corridor Data

When you bring AutoCAD Civil 3D alignment, profile and corridor data into an InfraWorks model, InfraWorks uses the centerline alignment and profile data to define the design road, and road and coverage styles to display the centerline and the areas corresponding to the corridor link styles.

A set of default style rules maps design road alignment and profile data to a centerline style, and maps corridor link styles to road and coverage styles.

  • The cursor is beneath the flat line marking the link representing the bottom of a roadside ditch.

The same corridor data brought into InfraWorks, which uses default style rules to display the road and coverage areas.

  • The cursor is at the coverage area for the bottom of the ditch, which is mapped to style Material/Land Cover/Gravel.
Note: You will need to download and replace these styles and style rules in your Program Data folder before InfraWorks can use them to display the alignment and corridor data. See To load predefined style rules.

Style Rule Expressions Map Alignment Styles and Corridor Link Styles to Model Styles

The predefined style rules use the expression, TAG = 'style name' to map alignment styles to design road styles and corridor links to coverage area styles.

Shown below are the 8 default Road style rules, loaded (Import All). Tab to Coverage Areas to see the 20 default coverage area style rules.

Note: These style rules are based on the AutoCAD Civil 3D alignment styles and link styles included in the standard templates that ship with Civil 3D. If you do not want to use these default style rules, create your own style rules to specify desired alignment styles and links styles.

Create Custom Style Rules for Displaying Alignment and Corridor Data

You can edit the default style rules or define new ones. See: To define style rules and About the Expression Editor.

You can create sets of customized style rules for others to use. After defining a set of rules, use Export All to store them in the model's Resources folder. Other users can then use Import All to load them. See To import style rules for displaying corridor data.
