It seems simple but i can't find the right perameters.
I need to daylight to an offset, to create a clear zone/fall zone, but it must have a maximum slope of 6:1. If no daylight is found at the offset and maximum slope, then grade at the maximum slope to the offset then daylight to the target suface at a steeper slope.
IT SEEMS LIKE IT SHOULD BE EASY BUT I CAN'T FIND IT.
Solved! Go to Solution.
I don't see any of the standard SA that would do this. The daylight standard gets close, but would have a fixed clear zone slope.
You should be able to make it with Subassembly Composer pretty quickly.
1. Set a test point on the surface at the offset
2. Check the slope to the test point
A. If it is below 6:1 add a daylight point and link
B. If it isn't, add a point at 6:1, and then daylight from there
I'm not sure what you need in a cut.
I considered that, but I don't think that doesn't provide the solution where you can daylight at less than 6:1. I think this could be done with a pretty simple PKT file made with Subassembly Composer.
Although it may be time to learn the Subasembly Composer, I currently have no idea how to use it. I am hoping for a solution using some combination of the standard assemblies.
Can you provide a little more detail about your sugested solution? Can this solution be adapted to daylight at less than 6:1 at the specified offset?
Here is a quick version of a SA that should do what you are looking for in Fill. I didn't add link and point codes, but it might get you started.
If we assume for the moment that we're only dealing with the scenario on the left side of your sketch then there are several subs which might work.
Steve's solution will work. His post needs more detail. What his image shows is that the conditional subassembly is moved over X feet. There you can test the depth of cut or fill. We know what this needs to be - based on the slope times the offset. At the ends of the conditonal sub assemblies, Move the remaining subassemblies back X feet.
Instead of moving subassemblies, I use generic links with the omit option set to Yes. That helps me keep the pieces connected correctly, and allows for easy editing of the offset distances. The following image shows this with the width and slope generic link.
The final assembly would look something like this:
