I am having trouble getting my corridor to tie to the existing surface. It ties fine at the locations of template drops, but at other locations it doesn't quite make it to the existing surface. I am using the daylight general sub assembly and my heights for the different types of fill are set at 40' and 80' so it should be fine. There is plenty of existing surface for it to tie in to too. This is only occuring as a problem in the fill areas.
I've attached a pdf that shows a couple of cross sections that work fine as well as a few that show how it isn't working properly everywhere.
