You can bring Autodesk InfraWorks data into Autodesk Civil 3D by referencing a local Autodesk InfraWorks model or an IMX file that was exported from InfraWorks. You can bring Civil 3D data into InfraWorks by linking to a Civil 3D DWG file as a data source.
You can complete your initial design with InfraWorks and then bring the InfraWorks model into Autodesk Civil 3D to continue the detailed design.
Alternatively, you can start your project in Civil 3D and then bring it into InfraWorks when you want to create a design presentation or complete more design work in InfraWorks.
Use InfraWorks to complete your initial design |

Open the model in Civil 3D and use Civil 3D to continue your detailed design |
Corridor created when the InfraWorks component road is brought into Civil 3D Assembly created when the InfraWorks component road is brought into Civil 3D |
For more information about how to bring a Civil 3D drawing into InfraWorks, see About Exchanging Data with Autodesk Civil 3D and To Add Autodesk Civil 3D Data to an InfraWorks model in the InfraWorks Help.
You do not need to have Autodesk InfraWorks installed on the same computer as Autodesk Civil 3D in order to bring InfraWorks data into Civil 3D. However, the option to open a local InfraWorks model (SQLITE file) is only available if you have InfraWorks installed on the same computer. If InfraWorks is not installed, you can bring InfraWorks data into Civil 3D using an IMX file that was exported from InfraWorks.
Within InfraWorks, the option to use a Civil 3D DWG is available if Civil 3D is installed on the same computer as InfraWorks.
When preparing to exchange objects between an InfraWorks model and a Civil 3D drawing, it is recommended that you use the following guidelines when setting coordinate systems and units:
An object settings file specifies what types of InfraWorks objects will be brought into Civil 3D and also specifies settings for the objects. You can set up multiple files to handle different scenarios.
Pre-defined object settings files are provided in the following folders:
The following pre-defined object settings files are provided:
The following table lists what types of InfraWorks model objects can be brought into Civil 3D and what types of Civil 3D drawing objects they become.
