Rural intersection: edit shoulder foreslope to match ditch behind curb and gutter
Total video time: 6:03
Last updated: 2020-10-26
Here we will look at optional edits for the transition between the shoulder area into the curb return area. If this transition requires a higher level of precision such as when a culvert pipe depth is a concern, then transitioning from a 4:1 slope to a 6:1 slope will help match into that curb return area and reduce the amount of awkward transition. There are some subassembly parameters that respond well with the slope/width control editor.
