The Civil 3D Hydrology Toolbox Exposed

Have you ever wondered how the hydrology tools that are built into Civil 3D work and what the differences are? Would you like to get the most out of your gravity pipe networks by integrating them into the design process? AutoCAD Civil 3D has three hydrology applications that work with pipe networks and other Civil 3D features. Improve your efficiency and productivity by knowing which hydrology solution would be the right tool for your current design needs.

This eight (8) hour course is delivered in four (4), two-hour long sessions that students can attend online, right from their own desk. A live instructor will explain the detailed functions, and address questions as the class progresses.

Note: Instructor will present using Autodesk AutoCAD Civil 3D 2025. Students who wish to follow along with instructor are encouraged to use the same version.

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

Recording: Registrants for this 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.
