Placing Grading Objects
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.
New Grading Object Select in the Drawing Select in the Tool Palette Press Enter Adjust Settings in Dialog Building Pad Must be closed geometry: polyline, 2D polyline, 3D polyline, feature line, hatch, or parcel. Building Pad
Press Enter Building Pad Properties Panel Reveal Reveals are placed on the edges of building pads. Refer to the Reveals topic for the placement procedure. Reveal
Press Enter Reveal Properties Panel Pathway line, polyline, 2D polyline, 3D polyline, or feature line. Pathway
Press Enter Pathway Properties Panel Pond Must be closed geometry: polyline, 2D polyline, 3D polyline, feature line, hatch, or parcel. Pond
Press Enter Pond Properties Panel Retaining Wall Can be open or closed geometry: polyline, 2D polyline, 3D polyline, feature line, hatch, or parcel. Retaining Wall
Press Enter Retaining Wall Properties Panel Curb Can be open or closed geometry: polyline, 2D polyline, 3D polyline, feature line, hatch, or parcel. Open geometry creates curbs and closed geometry creates islands. Curb
Press Enter Curb Properties Panel Parking Lot Must be closed geometry: polyline, 2D polyline, 3D polyline, feature line, hatch, or parcel. Parking Lot

Press Enter Exclusion Zone Properties Panel Grading Limit Must be closed geometry: polyline, 2D polyline, 3D polyline, feature line, hatch, or parcel. Grading Limit
Press Enter Grading Limit Properties Panel Aligned Edge line, polyline, 2D polyline, 3D polyline, or feature line Aligned Edge
Press Enter Aligned Edge Properties Panel Bend Line line, polyline, 2D polyline, 3D polyline, or feature line Bend Line
Press Enter Bend Line Properties Panel Drain Line line, polyline, 2D polyline, 3D polyline, or feature line. Note: Drain lines cannot be a closed loop to work correctly. Drain Line
Press Enter Drain Line Properties Panel Ridge Line line, polyline, 2D polyline, 3D polyline, or feature line. Note: Ridge Lines cannot be a closed loop to work correctly. Ridge Line
Press Enter Ridge Line Properties Panel Low Point COGO point, AutoCAD point Low Point
Press Enter Low Point Properties Panel Bounded Point COGO point, AutoCAD point Bounded Point
Press Enter Bounded Point Properties Panel Offset Points line, polyline, 2D polyline, 3D polyline, or feature line. Note: As sketched, the start of the line will be the higher elevation and the end of the line will be the lower elevation. Offset Points
Press Enter Offset Points Properties Panel Note: Geometry cannot intersect with itself to be an eligible Grading Object.Continue adding grading objects in your drawing.
Tip: If you need to go back and change constraints on an object that you created, select it in the Grading Objects Browser. You can press and hold Ctrl while selecting multiple objects of the same category. Use the Grading Object Properties panel to edit their properties.To reference all the grading objects as you refine your drawing, use the Grading Objects Browser. Click Analyze tab > Grading Optimization panel >
Grading Objects Browser.
Tip: You can click Analyze tab > Grading Optimization panel >Grading Objects to display both the Grading Object Tools Palette and the Grading Objects Browser.
Be sure to save your drawing periodically.
