This write up tackles a simple design solution: to build up the existing slope by projecting from the existing top and bottom edges. Below, we explore the use of Corridors and Grading to solve a design need.
- From the Existing TOP Slope grade down at Negative -2% grade.
- From the Existing TOE Slope grade up at a Positive 1:1 slope.
- Stop where the 2 projections meet each other.
OPTION 1: CORRIODRS
The design can be accomplished by paring up two subassemblies:
When assembled and applied correctly within a corridor, the expected design fills in correctly:
OPTION 2: Grading Objects
Grading solutions will recognize each other can clean up. For this example, it doesn’t matter the order of operations.
Isolating the First Grading solution; is a Grade to a Distance (-2%) that would be wide enough to cover the needed distance.
Continuing with an isolated view, next is a Grading solution that is tall enough Slope (1:1) to exceed the TOP of the embankment.
When grading solutions are paired and grading objects run into each other, the solution is a clean slope.
Either method could work (corridors or grading), it just depends on what tools you favor.
