2 Verify the correct corner is selected. The current corner vertex number and its
X, Y coordinates and the corner elevation are displayed in the dialog box.
TIP
You can move between corners by clicking the following buttons in the
dialog box:
Selects the first corner
Moves back one corner
Moves forward one corner
Selects the last corner
3 Select a corner treatment for the corner:
n
Convex Miter Projection
n
Convex Radial Projection
n
Convex Chamfer
n
Convex, No Cleanup - Leaves the edges of your grading object as-is.
4 You can enter a new elevation for the corner in the Elevation box and/or select
a new corner treatment.
5 Click OK.
Configuring the Grading Accuracy Settings
The location and number of projection lines along the footprint determine the
accuracy of the daylight line and the volume calculations. With straight-line
segments and concave arcs, the increment distance is the distance between the
projection lines on the footprint. With radial corner treatments and convex
arcs, the increment distance is applied as an average distance between
projection lines at the daylight line. The smaller the increment number, the
closer together the projection lines are, giving you increased accuracy of the
daylight line and volume calculations.
