Civil 3D Pressure Networks

Use this skill when creating, modifying, or querying pressure pipe networks, fittings, appurtenances, or pressure parts lists.

Overview

Pressure pipe networks represent pressurized utility systems such as water distribution, fire protection, gas, and irrigation lines. Unlike gravity networks (which rely on slope and invert elevations), pressure networks are defined by operating pressure, pipe material ratings, and connection fittings. Pressure networks have three part categories — pipes, fittings, and appurtenances — compared to gravity networks which have pipes and structures.

Key differences from gravity networks:

• Pipes have pressure ratings and material specifications rather than slope-driven inverts
• Connections use fittings (tees, bends, crosses) instead of structures (manholes, catch basins)
• Appurtenances (valves, hydrants, meters) have no gravity equivalent
• Parts lists are separate: pressure parts list vs gravity parts list
• Label style collections use three separate accessor methods, not a single hierarchy
