To add AutoCAD Civil 3D data to an InfraWorks 360 Model

Bring detailed designs from an AutoCAD Civil 3D DWG drawing into your InfraWorks 360 model by linking the AutoCAD Civil 3D DWG drawing as a data source. Alternatively, you can add an Autodesk IMX file that was exported from AutoCAD Civil 3D to your InfraWorks 360 model (use the IMX workflow if you do not have AutoCAD Civil 3D installed locally).

  1. Click .
  2. Click in the Data Sources panel.
    Do either:
    • Click Autodesk IMX and select the desired IMX file, then click Open.
    • Click Autodesk AutoCAD Civil 3D DWG and select the desired AutoCAD Civil 3D DWG drawing, then click Open.
    The Choose Data Sources panels appears and lists which data can be brought in as InfraWorks 360 model objects. (InfraWorks 360 will perform a conversion on AutoCAD Civil 3D drawing objects when you bring AutoCAD Civil 3D data into InfraWorks 360.) By default, the data you bring in from AutoCAD Civil 3D is sorted by Feature class, unless you chose to sort by Source Type in the Data Sources panel.
  3. Choose the data source types to bring into the model at this time and click OK.
  4. Refresh the selected data sources from the right-click menu or click .
  5. Click OK.
  6. InfraWorks 360 displays the added data as InfraWorks 360 features.
    Note: Consult the table below for more information.
    AutoCAD Civil 3D drawing object becomes... InfraWorks 360 model object Notes
    TIN surfaces Terrain surfaces
    • Each surface is listed in the Data Sources panel.
    • Click to adjust the order of terrain surface layers.
    Alignments and profiles Design roads (horizontal and vertical geometry)
    • Only Centerline type alignments can be brought in as design roads.
    • A single profile is used for each design road, based upon the first finished ground profile that was created in the AutoCAD Civil 3D drawing. Use Profile View to review the profile geometry.
    • Best fit profile entities are not brought into InfraWorks 360.
    Corridors and Corridor surfaces Coverages and terrain surfaces
    • We recommended that you create one or more corridor surfaces in AutoCAD Civil 3D to bring into InfraWorks 360.
    • AutoCAD Civil 3D link styles are used to create coverages in InfraWorks 360 which show the materials of the corridor. The coverages allow you to stylize the different corridor components like pavement.
    Pipe Networks Pipelines with inlets and manholes or pipeline connectors
    • If a structure in the AutoCAD Civil 3D drawing has a Drainage Utility Type specified and is using the new default parts catalog with component object parts for pipeline connectors, InfraWorks 360 will use the same component object parts. When there is no match of pipeline connector parts, generic objects are displayed.

Additional information

Before refreshing newly linked road data, avoid bringing in duplicate roads. If an AutoCAD Civil 3D drawing was created by opening the current InfraWorks 360 model in AutoCAD Civil 3D, when you bring the road data back into the model, InfraWorks 360 brings in ALL of the alignments present in the DWG drawing, which results in duplicates of the roads already present in the current model.

To avoid duplicate roads, before you refresh the sourced data:

  1. Create a new proposal.
  2. In the new proposal, delete the design roads you plan to bring in from the AutoCAD Civil 3D drawing.
  3. Right-click Roads in the Data Sources panel and select Configure to open the list of roads being added.
  4. Turn on only the design roads you want to bring back in from AutoCAD Civil 3D.
Note: InfraWorks 360 uses predefined style rules to style the display of AutoCAD Civil 3D data that translates into design roads, centerlines, and associated coverage areas. You can edit or define new styles and style rules to customize the display of corridor data in InfraWorks 360. See About Using Styles to Display Civil 3D Corridor Data.
