The Autodesk(R) Civil 3D(R) 2025 software supports a wide range of civil engineering tasks and creates intelligent relationships between objects. The Autodesk(R) Civil 3D(R) 2025: Beyond the Basics for Grading guide is recommended for users who create or manage site grading plans using the Autodesk Civil 3D software. This learning guide covers the use of feature lines, grading tools, and corridors to create a commercial site containing a parking lot, building pads, pond, and simple sewage lagoon. A road has been included in the survey, for which the existing conditions were collected by a survey team. The practices have been designed to allow you to practice grading lots in a small residential subdivision.

The learning content in this guide assumes that the existing conditions are already processed. To learn how to create the existing conditions, refer to Autodesk(R) Civil 3D(R) 2025: Essentials for Surveyors.

Topics Covered
