Control over daylighting

[Anonymous]

LDD3
I am attempting to design some slope correction along the side of an
existing road. Here is what I have done so far:

1. Created a 3D polyline at the edge of road to represent the proposed
bottom of fill
2. Used Grading --> Daylighting --> Create Single in an attempt to find out
where my proposed slope would meet existing ground.
3. Used Grading --> Daylighting --> Daylight Polyline to bring in the
daylight line.

I get a daylight line in the same place as my original bottom of fill line.
For a quick fix, I tried elevating my fill line slightly, but then it just
grades down to the road again, instead of up to the bank which is further
away. I experimented with the cut and fill grades and slopes and was unable
to get the results I wanted.

Any suggestions on a fix for this way of doing what I'm trying to do? Or a
completely different way? I can draw 3D lines at a slope, is there a way to
make them stop at a surface intersection?

Thanks to anyone who can help

Hi Justin, try clearing "all" daylite info & reset or you BF is too close to
Exist.... Ahhh are you certain, maybe, you are entering a slope value
instead of % grade or vise verse.

random daylite at the bottom of the pulldown shoul be of use to you.

I'm not 100% sure of what you are trying to attempt, but it seems you are
trying to grade up from the road (existing surface) to an existing slope
(existing surface)? If so, one way would be to use a grading object using
your 3D poly (at the edge of the road) to create a cut (cut up, fill down)
slope for a 'distance' of say 30' (or however far you need to cover your
slope). Then create a surface from that GO, create a stratum between that
GO-surface and your existing surface. Create a contour (use the polyline
option) at elev=0 based upon your volume surface. This line will represent
the daylight.

Re-post if my assumptions are off.
