I’m modeling vegetated slopes on a large site (125 AC). The design depicts the bottom swale and includes a detail for the swale at 4:1.
I’ve entered the bottom swale and added VPI’s at the flow line callouts. Next, I used Offset/Slope to calc the 4:1 at a 2.5’ offset. When I add to my design surface, it’s clear the proposed contours did not account for the swale.
As a work around, I’m trying to use Slope Designer to tie the bottom of swale to the proposed surface at 4:1 - but I can’t get it to work. Anyone else have experience with this issue?
Use RPSCrop Crossing Lines to remove the contours between the lines you’ve generated?
Yup, It looks like you have crossing break lines set at different elevations. The software can only define one elevation at a given point in a surface. Depending on what the other lines are, you have a couple of options to deal with the crossing break line. If its a contour, you can trim out a section (like Eriks recommendation) for your ditch bottom to pass through. If it’s an actual break line though, you can add vertical points, at the crossing location (to the crossing line), with an elevation snapped to the ditch bottom line as well. This doesn’t answer your question regarding slope designer, but I think you can get it to work with your original approach.
