You place grading objects by assigning them to Civil 3D drawing elements. Once assigned, the grading object information is saved as Property Sets in the drawing.
Open your drawing.
Click Analyze tab > Grading Optimization panel > Grading Object Tools to open the Grading Object Tools Palette.
This tool palette is similar to others in Civil 3D. You can right-click a tool to cut/copy, paste, and rename to create your own preconfigured tools. Right-click and select Properties to set the default settings for the tool in the appropriate Grading Object Tool Properties Dialog.
To place a grading object in your drawing, use the following table to reference the steps and criteria for the object geometry.
