Gravity Feed Networks for Civil 3D

The Gravity Feed Networks in Civil 3D course series takes the guesswork out of gravity pipe design and shows you how to use Civil 3D’s pipe network tools the way they were intended. You’ll start by setting up catalogs, parts lists, and rules, then build and edit gravity networks efficiently in plan view. From there, the series moves into profile and section workflows - where many designs break down - so you can confidently control elevations, labels, and documentation. With added exposure to pressure pipe workflows, this series prepares you to handle real-world utility designs with accuracy, clarity, and far less rework.

This live online series offers 2 four-hour courses. You can take both courses or just the one that meets your needs. Each separate course is delivered in 2 two-hour sessions. A live instructor explains the detailed functions and addresses questions as the class progresses.

Note: Instructor will present using Autodesk Civil 3D 2026. Students who wish to follow along with instructor are encouraged to use the same version.

Prerequisite: Students should have a working knowledge of Autodesk Civil 3D.

Recording: Registrants for a course will receive access to a recording of each session for 7 consecutive days. Access will start the next business day after the session ends.
