Ok, the rundown here.
I'm working on a project to take a 4:1 slope to a 5:1 slope while also filling a ditch at the bottom.
My issue is getting a template to work. I'm not sure if this is something I could do in one template and drop an alignment or if it will take two or more of any.
I'm coming off the crown which is ~5' off the centerline some more some less but I have a breakline on the crown so I'm running off that.
Then at the bottom there are some spots with a ditch along the bottom that needs filled, the issue is I have a 100' work limit from the centerline that I can't come past.
These are the three things I'm needing it to do.
5:1 if there's no ditch or minimal.
-Fill ditch @1% slope away, tie in on each end. Plus a 5:1 slope for the bank
-Fill ditch, Tie in on left, go to the 100' mark on right, then drop off at 5:1 slope to right to meet existing ground. Plus a 5:1 slope for the bank.
-I don't work with templates often enough to understand this one so there's my struggle, I've had some other try to help me and while they work, they go past the work limits which is a hard limit for me right now.
If someone is able to help me, I would greatly appreciate it. I don't mind doing two templates for a fill then run the slope to meet if that's what it takes.
So while not the way I was hoping I did come up with this.
Using two separate templates I got that which I kind of need to pull quantities anyways for the way we are breaking it out.
Ran the slope first.
Then the fill. I was trying to tie it into the slope but I don't think I did it right.
What's everyone's thoughts on that one? Will that fix that once I merge terrains together? or do I need to do something else in there?
If you want to measure the extra material for the ditch backfill separately from the general embankment material, your fundamental logic works: find the limits of the embankment, then backfill the ditch. I do have a couple of questions (I'm always good for those).
How are you determining where to apply the second template? In other words, how do you know you're at a location with a ditch?
I'm not clear on the purpose of the detached points (_R in the first template and 2_R in the second). In the second template, are the two elements separate end conditions strung end to end or a single end condition?
If in a ditch section, I would create a point at 470 along the general embankment slope on the way down to the catch. After catching the main fill slope, I would go back up to the 470 point and seek the existing ground to the right, if that failed I would seek the work limit, then catch the existing ground on the 5:1 slope. If you assign different alternate surfaces to the main fill and the backfill, you could do all of this in a single pass and have the separate surfaces for measuring quantities.
You could also incorporate solutions for other scenarios (e.g. the ditch bottom is above 470 or the main fill slope catches above 470), all in a single pass, with more complicated templates.
The key to all of these solutions is determining whether or not you're in a ditch section. You can do this manually and adjust your templates accordingly or use end condition exceptions. Or you can create identifying the ditches (or use existing, surveyed, features) and test for those in the end conditions.
