Exporting Pipe Network Data to an .stm File

2012-03-14

Product Documentation

Intermediate

You can export pipe network data from AutoCAD Civil 3D to an .stm file.

The .stm file can then be opened bythe Hydraflow Storm Sewers exstension for analysis and editing. After editing the file in Storm Sewers, you can import it back into AutoCAD Civil 3D. Changes made to the file while in the Storm Sewers extention are recognized in AutoCAD Civil 3D.

You can export one or more pipe networks into an .stm file. You must choose entire pipe networks. You cannot export individual parts, or a set of connected parts within a pipe network.

It is important to note the following before exporting pipe networks to an .stm file (or any type of export of pipe data):

If a pipe does not have an upstream structure in AutoCAD Civil 3D, it is given a null structure in the exported file.
If a structure is not attached to a pipe, the structure will not be exported.

Note

You cannot open .stm files that were exported from AutoCAD Civil 3D, or that were saved in the Storm Sewers Extension for Civil 3D 2010, in the Storm Sewers Extension for Civil 3D 2009, or earlier versions of the Storm Sewers Extension.
