Grading Object Usage Tips

The following illustration shows a grading object with interior miter cleanup

and changing footprint vertex elevations. The slope is always constant

throughout the corner, so a drop is formed at the center of the cleanup. In this

case, the object is behaving as designed.

Grading object with changing vertex elevations

This illustration shows a grading object with changing vertex elevations and an

absolute elevation target, showing interior miter corner cleanup. Notice the

drop at the center of the corner. This is how the object is designed to handle

this case.

Accuracy

Fixed Incremental vs. Automatic Spacing

Although projection line spacing created with the Use Automatic Spacing

with Increment setting produces the most accurate daylight line, there may

be situations where gaps occur in the projection spacing. Although this is

rare, it may be solved by changing the accuracy method to Use Fixed

Incremental Spacing.

Automatic Spacing and Elevation and Distance Targets

Automatic spacing does not apply to elevation or distance targets: By

definition, automatic spacing finds projection lines where the slope intersects

TIN lines of the target surface. With elevation or distance targets, there are no

TIN lines to intersect, so the program will apply the specified increment

spacing.
