SmartDraft Grading by Polyline Tools return polyline grading tools lost between Land Desktop and Civil 3D:

• Edit polyline elevation: Change the elevation of any 2D polyline in the drawing.


• Edit polyline datum elevation: Changes 2D polyline elevations by adding or subtracting a specific amount.


• Assign polyline elevation: Enter the elevations for selected polylines.


• Check for 0 elevation polylines: Select a group of polylines, to check if they have an assigned elevation, if the elevation is zero, prompt for a new elevation.


• Offset polyline by Rise/Run: Offset polylines at a calculated distance from the entered elevation interval, rise, and run values.


• Offset polyline by slope (%): Offset polylines at a calculated distance from the entered elevation interval, and percentage of slope.


• Offset polyline by slope (%) and distance: Offset multiple polylines at a calculated distance from the entered elevation interval, and percentage of slope until it meets the specified distance.


• Offset polyline by slope (%) and elevation limit: Offset multiple polylines at a calculated distance from the entered elevation interval, and percentage of slope until it meets the specified elevation.


• Change polyline layer by elevation: Change selected polylines to major and minor contour layers at specified elevations.


• Edit elevation of polyline: Change the elevation (z) value of selected 2D polylines. Select the polylines in increasing or decreasing elevation order. Command increments the selected polyline's elevation by the specified interval.


• Volume from Polyline (Contours):Current limitations of the calculations. Command assigns each polyline (contour) is fully with the previous polyline. Each polyline must an an area less/greater than the previous polyline. The command does not subtract volumes due to islands in a pond/basin, or hole in a stockpile.
