To Bring Autodesk InfraWorks Data into Autodesk Civil 3D

You can bring Autodesk InfraWorks data into Autodesk Civil 3D by selecting a local model or an IMX file.

1. Click Insert tab InfraWorks panel InfraWorks Open InfraWorks Model Find.
2. In the Open InfraWorks Model dialog box, specify an InfraWorks model to open. You can select a local InfraWorks model by selecting an SQLITE file, or you can select an IMX file that was exported from InfraWorks.
   Note: You can open SQLITE models to bring InfraWorks bridges into Civil 3D, but bridges that are brought into Civil 3D from an SQLITE model cannot be updated using the InfraWorks Dataset Manager dialog box.
3. Review the information under Coordinate System, and click Set a Coordinate System if you need to specify or change the coordinate system of the drawing. Autodesk Civil 3D must have a coordinate system specified in order to bring in InfraWorks data.
4. If you selected an InfraWorks SQLITE file in step 2, you can use one of the following Selection Area options:
   • Click Extents of InfraWorks Model to open the entire model.
   • Click Area of Interest and then click Select Area to select an area. This option turns on the display of online map data in your drawing and enables you to select an area from the map. When you select an area of the map, the rectangle that forms the selection window acts as a boundary for the surfaces that will be brought into Autodesk Civil 3D. Other objects, such as roads, that are inside or that cross the selection window will be brought into Autodesk Civil 3D in full.
     Tip: Using the Area of Interest option to limit the area that is imported may result in a faster processing speed for the command.
5. Specify the object settings file to use by selecting the folder in which it is located and selecting the file to use.

   Pre-defined object settings files are provided in the following folders:

   • C:\ProgramData\Autodesk\C3D 2025\enu\Data\InfraWorks Object Settings\Metric
   • C:\ProgramData\Autodesk\C3D 2025\enu\Data\InfraWorks Object Settings\Imperial
6. Refine the selection set of objects by clicking Refine Selection Set. Use the Refine Selection Set dialog box to refine the object selection and click OK.
7. Click Open Model.
