When you bring AutoCAD Civil 3D alignment, profile and corridor data into an InfraWorks 360 model, InfraWorks 360 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.

Style Rule Expressions Map Alignment Styles and Corridor Link Styles to Model Styles
InfraWorks 360 uses predefined style rules to map alignment styles to design road styles and corridor links to coverage area styles. 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 style rules, you can edit the default style rules or define new ones to specify desired alignment styles and links styles. See: To define style rules and About the Expression Editor.
The Null Road style is used to visualize the centerline of a design road created from the alignment and profile data in an AutoCAD Civil 3D corridor. Null Road style allows centerline geometry (alignment) to display in InfraWorks 360 without being hidden by coverage styles used in the translation which are mapped to other link styles.
Shown below are the 8 default Road style rules. Tab to Coverage Areas to see the 20 default coverage area style rules.
Create Custom Style Rules for Displaying Alignment and Corridor Data
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.
