You can use the Storm Sewers extension to open and edit pipe networks created with Autodesk Civil 3D.
To open pipe networks in the Storm Sewers Extension, they must first be exported to an .stm file.
The .stm file can then be opened by the Storm Sewers Extension and edited.
For example, you can create pipe networks in Autodesk Civil 3D and then import those pipe networks into Storm Sewers to perform analysis tasks. After performing hydraulic analysis tasks on the pipe network, you can then import that same pipe network back into Autodesk Civil 3D.

You can also use the EditInStorm Sewers command to browse to an .stm file, and automatically open it in the Storm Sewers Extension.
For more information about using the Storm Sewers Extension to edit pipe networks, see the Storm Sewers Extension Help.
When you are finished making changes to the pipe network in the Storm Sewers Extension, save the project to save the changes to the .stm file.
You can import that .stm file back in to Autodesk Civil 3D and update the previous version of that pipe network data, if desired. You also have the option of importing it with a new pipe network name.
