Introducing importing and exporting with Civil 3D

Discover requirements and workflows for InfoDrainage to Civil 3D interoperability.


The InfoDrainage for Civil 3D plug-in is designed to allow engineers to exchange information with InfoDrainage by importing and exporting drainage networks within Civil 3D.

If you have installed InfoDrainage using the Innovyze system, you can download the Civil 3D plug-in from the InfoDrainage download page on the Innovyze Support Portal.

If you have installed InfoDrainage using the Autodesk system and already have Civil 3D on your machine, the Civil 3D plug-in is installed as part of the Ultimate installer.

Once installed, the plug-in automatically adds in the InfoDrainage tab to the ribbon when Autodesk Civil 3D is launched.

Ideally, the surface model would be designed first in Civil 3D, and then imported into InfoDrainage for the hydrology design.

During this process, it is important to understand how InfoDrainage objects behave in Civil 3D.

A list of the InfoDrainage objects that are easily imported into Civil 3D—manholes, connections, pipes, and inflows—and those that may need user input—stormwater controls, inlets, and outlets.

Be aware that development of the interaction between Civil3D and InfoDrainage is ongoing. It is also important to realize that InfoDrainage only considers runoff from impermeable areas, such as roads and roofs. It is primarily used for stormwater, but similar principles would apply to sanitary systems as well.
