Grading Design in Civil 3D

Understanding the wide array of grading creation and editing tools that are available in Civil 3D is one of the greatest struggles for designers and technicians. Taking those tools and applying them to an actual Residential Site Design is even more difficult. This class teaches students practical use of Civil 3D Grading functions by developing grading for a proposed site, across all class sessions. This class is more than just an explanation of available grading tools. It teaches students how to use them on real world projects to generate realistic grading results.


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 course progresses.

Note: Instructor will present using Autodesk AutoCAD Civil 3D 2020. Students who wish to follow along with instructor are encouraged to use the same version.

Recording: Registrants for this course will receive access to a recording of each session for 48 consecutive hours. Access will start the business day after the session ends.
