Before you create grading, you need to select a grading group to associate the grading objects with. After you create a grading object, you can move it to a different grading group within the same site.

Feature lines and grading are created by default on the layers specified by the drawing settings.

Use the Grading Creation Toolsto specify the grading criteria and style for the grading. Then create the grading by selecting the footprint from which the grading is projected. Command prompts vary, depending on the values that have been set in the grading criteria. For example, if the criteria has a target of Distance, which is not locked, you are prompted to enter a number for the distance.
