# How to set Gravity Network Pipe/Structure Catalog

## Motivation

An important distinction between **Gravity Network Catalog** and **Pressure Network Catalog** is that [the path for the former is set on a *per machine* basis, whereas for the latter, it is set on a *per drawing* basis](/docs/part-size-part-family-parts-list-and-network-catalog-for-gravity-and-pressure-networks/). This guide serves as a handy, comprehensive reference for those who want to set the Gravity Network Catalog for Pipe and Structure.

To do this via C# code, refer to [here](/docs/set-gravity-and-pressure-network-catalog-via-code/)

## The UI Way

Click **Home** tab → **Create Design** panel → **Set Pipe Network Catalog**, as shown below:

![Set Pipe Catalog](/wp-content/uploads/2025/04/set-pipe-network.webp)

This will open the **Pipe Network Catalog Dialog Settings**, allowing you to specify the Pipe and Structure Catalog.

## The Command Line Way

**Command Line** here refers to the Command Line in the Civil 3D application and not the Windows command line.

You can use the command [`_aeccsetnetworkcatalog`](https://forums.autodesk.com/t5/civil-3d-customization/how-to-set-part-catalog-via-api-for-a-drawing/td-p/13064638) to call up the **Pipe Network Catalog Dialog Settings** above, allowing you to specify your Pipe and Structure Catalog.

## The Registry Way

Knowing where the settings for the Pipe and Structure Catalog are stored in the registry is important if [you want to write a script](https://forums.augi.com/showthread.php?173339-Automate-SETNETWORKCATALOG-value-for-multiple-client-standards-for-Civil-3D) to automate the setup of all part catalogs on new machines when you have custom default catalogs.

The settings for the Pipe and Structure Catalog are stored in the following registry location:

```bash
ComputerHKEY_CURRENT_USERSoftwareAutodeskAutoCADR25.0ACAD-8100:409Profiles<<C3D_Metric>>PreferencesAeccUiNetwork130
```

Where

- `R25.1` = Civil 3D 2026
- `R25.0` = Civil 3D 2025
- `R24.3` = Civil 3D 2024
