The following illustration shows the Corners tab in the Grading Properties
dialog box.
2 Under Convex (Outside) Corner Treatment, select a corner treatment. For each
selection a corresponding graphic illustrates the selected corner treatment.
n
Miter Projection: Miters a convex corner of the grading object by creating a
slope projection line at that corner which bisects the bend angle at that
corner. The slope projection line stops at the grading target (daylight).
Additional slope projection lines are created that originate from this first
slope projection line. The spacing of these additional slope projection lines is
based on the Increment Along Straight Line Segments setting in the accuracy
settings.
n
Radial Projection: Rounds the corner of a grading object by projecting slope
lines radially to a target. The spacing of these lines along the daylight line is
controlled by the Increment Along Arc Segments setting in the accuracy
settings. The number of slope projection lines is based on the average
distance between slope projection lines at the daylight line. The average
distance is determined by fitting an arc at the beginning and end of the
radial slope projection limits, and dividing this arc by the increment setting.
n
Chamfer: Chamfers the corners of a grading object by creating two slope
projection lines at the corner. The first slope projection line is perpendicular
to the segment before the corner, and the second is perpendicular to the
segment after the corner. Additional slope projection lines are created from
these two slope projection lines. These additional slope projection lines are
parallel to the line that bisects the angle formed by the convex corner. The
spacing of these additional slope projection lines is based on the Increment
Along Straight Line Segments in the accuracy settings.
n
No Cleanup: Leaves the corners of a grading object as-is.
