You can migrate pipe network data between AutoCAD Civil 3D and the Storm Sewers Extension.
For example, with AutoCAD Civil 3D, you can:
When importing Storm Sewer data into AutoCAD Civil 3D, you can import a single pipe network, or multiple pipe networks. However, you must import entire pipe networks; you cannot import individual parts, or a series of connected parts within a pipe network.
There are a few preparatory tasks to perform before migrating data between AutoCAD Civil 3D and the Storm Sewers Extension. The table below summarizes these tasks.
| Task | Description |
|---|---|
| Verify that your pipe network data meets the necessary criteria for migration | Review the criteria for migrating pipe network data. |
| Create the parts list that will be used during migration | When you import or export pipe networks between AutoCAD Civil 3D and the Storm Sewers Extension, a parts list that contains appropriate parts for the import or export is required. You will need to create this parts list first, before you begin importing or exporting the data. You may need to create a full parts list, containing all of the available parts in the entire catalog, or you may need to create a smaller, customized parts list that contains only the parts included in the migrated data. |
| Set the part matchup settings that will be used during migration | In Toolspace, on the Settings tab, you need to configure defaults that will be used for matching up part types between AutoCAD Civil 3D and the Storm Sewers. |
| Choose the default parts list that will be used during migration | In Prospector, on the Settings tab, you also need to choose the default parts list that will be when you migrate data between AutoCAD Civil 3D and the Storm Sewers. |
Optionally, you may want to create a label style for displaying labels for hydraulic properties, such as hydraulic gradient lines and energy gradient lines in pipe networks.
To successfully migrate pipe network data between the Storm Sewers Extension and the AutoCAD Civil 3D, the pipe network data must meet certain conditions. Verify that your pipe network data meets these criteria before migrating:
It is also important to be aware of the following before exporting pipe networks to an .stm file (or any type of export of pipe data):
In AutoCAD Civil 3D, you can import .stm files that were created or saved from older versions of the Storm Sewers Extension; for example, the Storm Sewers Extension for AutoCAD Civil 3D 2009 or earlier. You can also successfully open .stm files that were created or saved from 2009, or earlier, versions of the Storm Sewers Extension in the Storm Sewers Extension version 2010. However, in the Storm Sewers Extension for Civil 3D 2009, or earlier versions of the Storm Sewers Extension, you cannot open .stm files that were saved in the Storm Sewers Extension for Civil 3D 2010, or that were exported from AutoCAD Civil 3D.
It is also important to note that when importing .stm files that were saved prior to version 2010, they may contain hydraulic gradient line (HGL) values, however, they will not contain some of the other hydraulic properties, as listed below. The following values are calculated in the Storm Sewers Extension version 2010, but are not found in older versions of .stm files (prior to 2010):
Pipes
Structures
In the Storm Sewers Extension, the list of pipe sizes is hard coded and cannot be customized. This list does not distinguish between inner and outer pipe diameter, pipe material, or pipe class, as does AutoCAD Civil 3D. When you perform calculations that resize pipes in the Storm Sewers Extension, the results include only the sizes that are available in the hard coded list. This may result in a pipe size or sizes that are not typical of the pipe material they are working with. However, you can always manually edit the pipe size.
