See the following illustrations for "step by step" instructions on how to draw the elements and achieve the above results.
- Start with the original cross section and be sure that the fill slopes are elements meeting the criteria of proposed finished grade and that they do connect to existing ground.
- Draw the perimeter of the area to be backfilled with riprap at LV=9, CO=22 and connect the top and bottom to proposed finish grade, LV=10, CO=10.
- Trace the riprap area below existing ground at LV=57, CO=3... Existing Unsuitable. Connect to existing ground.
- The drawing above illustrates the finished drawing and all of the correct connections for the Proposed Finish Grade, Proposed Undercuts, and Existing Unsuitables.
Below is the complete log file containing the earthwork input file and the results.
For this example... I'm ignoring discussing the Proposed Undercuts, on levels 3 through 6. THEY ARE DRAWN BY CRITERIA AND ARE AUTOMATICALLY CALCULATED BY THE EARTHWORK INPUT FILE.
