Surface Mining - Design Bench Pit

[KFinlay1]

Hey All,

I'm getting my feet wet with the Surface Mining Module and I design a lot of quarries/pits mostly by hand (well by 3D polylines). I'd like to get good at the Design Bench Pit function in the Surface Mining Module however I'm running into some issues I was hoping someone could shed light on. In the attached picture there are vertical turquoise lines that create a very tall wall that are impractical adjacent to my ramp. Is there anyway to control these? Thanks in advance.
