To Work With Hydraulic Property Data for Pipe Networks

To add hydraulic property data to a pipe network

1. In AutoCAD Civil 3D, export the pipe network to an .stm file.
2. Launch the Storm Sewers Extension.
3. In the Storm Sewers extension, perform the hydraulic analysis tasks on the pipe network. This adds valid hydraulic property data (HGL, EGL) to the pipe network. For more information, see the Storm Sewers extension Help.
4. Export the pipe network from Storm Sewers to an .stm file. For more information, see the Storm Sewers extension Help.

In AutoCAD Civil 3D, import the .stm file that now contains valid hydraulic property data.

Verify that the AutoCAD Civil 3D pipe network contains valid HGL and EGL data.

To verify hydraulic property data

1. In AutoCAD Civil 3D, right-click a part in the pipe network and select Pipe Properties or Structure Properties.
2. In the Pipe Properties or Structure Properties dialog box, click the Part Properties tab.

Note the items listed in the Hydraulic Properties section. The values listed here are set when the pipe network is imported from the .stm file.

To edit the pipe display style for HGL and EGL

1. In Toolspace, on the Settings tab, expand the Pipe collection, then expand the Pipe Styles collection.
2. Double-click the desired pipe style to edit it.
3. Click the Display tab in the Pipe Style dialog box.
4. Select Profile in the View Direction drop-down.
5. For the Hydraulic Gradient Line and Energy Gradient Line components, turn on visibility, and set other display characteristics, such as color and layer, as desired.
