How to Grade a Commercial Site in Civil 3D Using Feature Lines | Civil 3D

In this tutorial, we walk through the practical steps of grading a commercial site in Civil 3D using feature lines. Whether you are defining building pads, managing site slopes, or setting up your initial drainage falls, feature lines are one of the most powerful tools for accurate surface grading. This video covers the complete workflow, from assigning initial elevations to checking the final graded surface in 3D. What you'll learn in this video: Feature Line Setup: Establishing feature lines for a commercial layout. Quick Elevation Editor: How to rapidly assign and adjust grades and slopes across multiple points visually. Elevation Editor Table: Fine-tuning your site grading for precision. 3D Object Viewer: Sending your design to the model viewer to verify your grading realistically in 3D. ⏱️ Chapters / Timestamps: 0:00 - Introduction to Commercial Site Grading 1:45 - Grading Entry/Exit Junction 10:00 - Grading the Road Area 22:34 - Fine-tuning with the Elevation Editor 32:48 - Featureline Editing Geometry If you found this tutorial helpful for your grading workflows, please hit the like button and subscribe for more civil engineering and drainage design tutorials.
