Configuring the Grading Targets Settings

2 Under Grading Target, select one of the following as the grading target:

Surface: To grade to a surface, select this option, and then select an existing

surface from the Surface list. The grading objects projection lines are

extended until they intersect with the surface. If the footprint is below the

surface target you are grading to, then the projection lines go up at the cut

slope value you specify in the slopes settings. If the footprint is above the

surface target you are grading to, then the projection lines go down at the fill

slope value you specify in the slopes settings. You can only select one target

surface per grading object.

NOTE

When you grade to a surface target you will get differing results

depending on whether the grading object is contained entirely on the

surface or if the grading object is partially off the surface. If the

projection lines from the grading object, either originating from a

footprint segment or a corner, extend beyond the edge of a surface,

then no projection lines are created along the entire segment. target

Elevation: To grade to an elevation, select this option, and then enter an

elevation to which the grading objects projection lines are extended. If the

footprint is below the elevation target you are grading to, then the projection

lines go up at the cut slope value you specify in the slopes settings. If the

footprint is above the elevation target you are grading to, then the projection

lines go down at the fill slope value you specify in the slopes settings. Select

Absolute if you want all of the vertices on the daylight line to be created at

the same elevation. Selecting Absolute makes the projection line stop at an

elevation relative to the elevation zero. Select Relative if you want all of the

vertices on the daylight line to be created the same vertical distance from

any location on the grading object. Selecting Relative makes the elevation

relative to the footprint at any point where a projection line is calculated.
