GIVEN FH = FillHeight
P3 = the hinge point (Edge of Shoulder).
SS = SideSlope
Assuming I've already tested for cut vs fill and I know I'm in fill:
If FH =< 2ft then SS=-16.66667% (6:1 Fill Slope)
If 2ft < FH =< 4ft then SS=-25% (4:1 Fill Slope)
If 4ft < FH =< 6ft then SS=-50% (2:1 Fill Slope)
If 6ft < FHt then SS=-1000% (Retaining Wall)
Using SAC 2012, the above would require 3 separate "Decisions" besides the one to test for cut vs fill.
I would like to be able to use a "Switch" and for the expression say TRUE. Then for each of the branches, I can insert my tests - if one is true, then its branch is followed. Here's a screenshot of SAC with the flowchart using the decisions to do this.
