The Autodesk® Civil 3D® 2021 software supports a wide range of civil engineering tasks and creates intelligent relationships between objects. The Autodesk® Civil 3D® 2021: Grading guide is recommended for users that are required to create site grading plans using the Autodesk Civil 3D software. This guide is also ideal for managers that require a basic overview and understanding of this aspect of the Autodesk Civil 3D software.

Users use feature lines, grading tools, and corridors to create a commercial site containing a parking lot, building pad, pond, and simple sewage lagoon. An existing road has been included in the survey and a survey team collected the existing conditions. Users also work on a residential site to grade a small subdivision for proper grading of each lot.

Topics Covered:

• Introduction to Grading
• Parcel Grading
• Grading using Feature Lines
• Grading using Grading Objects and Grading Groups
• Grading using Corridors
• Combining Surfaces
