Grading Optimization for AutoCAD Civil 3D

With the release of AutoCAD Civil 3D 2022, we now have the Grading Optimization tool, which is the biggest change to the grading process since the advent of Corridors. Grading Optimization allows you to define grading areas for items like zones, curbs, ramps, low points, parking lots, etc., using simple polylines. From there, AutoCAD Civil 3D handles the entire site grading process for you, even incorporating site cut/fill balancing, to provide you with the most efficient grading possible, all without you defining slopes, breaklines, and all the other controls you’ve manually put in for so many years.

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 2023. 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 next business day after the session ends.
