About Pressure Networks

You can use the pressure networks features to generate 3D models of pressure networks, such as water transmission systems.

Path-Based Pressure Networks

Dynamic path-based pressure networks were introduced in Autodesk Civil 3D 2021.
  • When creating a path-based pressure network, you select locations to define the path and the pressure pipes and bends are created with respect to grade and cover.
  • Modifying the path will update the locations, lengths, and angles of the connected pressure network parts.
  • You can add or remove bends and PIs along a pipe run and add branch fittings at the intersections of pipe runs.

Pressure networks created with the original commands are referred to as part-based pressure networks. In Civil 3D 2021, you can continue to create and edit part-based pressure networks, or you can convert them to path-based pressure networks by using the Create Pipe Run from Parts command.

The workflow when creating pressure networks consists of selecting locations in the drawing to define a pipe run along which, pipes and bend fittings generate. You can define and model a pipe run in both plan and profile views. One or more pipe runs generated from common part lists join to comprise an independent pressure network.

The pressure network workflows provide an introduction to the overall process of working with pressure networks.
