About Grading
Use the grading tools and commands in Autodesk Civil 3D to design finished ground surfaces.
About Grading Regions
You define grading regions where grading requires different criteria along different parts of the footprint.
About Grading and Surfaces
Grading groups can be automatically turned into surfaces that dynamically update when you edit the grading. You can also create a detached surface from a grading group, which is no longer associated with the gradings and does not update when you edit the grading.
About the Grading Collection (Settings Tab)
Use the Grading collection in the Settings tree to manage grading settings, grading styles, grading criteria sets, and grading command settings.
