Template Help

Are the ditch locations designed, or are they "wherever"? I mean, do they have a station range and profile or is the template supposed to figure that out?

In my mind, this calls for end conditions, probably stacked end conditions for part of it. You will also use at least one or two "seek points" - Do Not Construct points used to locate and direct other points (such as your 100' margin).

I'm no expert, but I would start my end conditions with the "simple" fill ditch. I know you have some kind of logic/criteria to determine how and where that will happen. The important part is that it will not solve if it doesn't tie to existing ground within your 100' buffer. If it doesn't solve, it will go to the next end condition. Give this Priority 1

Which in my mind would be the third "open air" fill ditch. I would approach this with DNC (construction) elements first. One line out to your 100' mark, and then another one "down" to your ditch elevation. One last DNC element drawn from that point back toward your centerline. At that point, you can switch back to regular components and draw your 5:1 down to the elevation construction, then another component at that elevation over to your 100' mark. Then you draw the last tie line to existing. This would have Priority 2

Last would be the "plain" 5:1 down to ground, because that's the "Do this if we aren't doing anything else" so it would be priority 3.

But like I said, I'm no expert, and there are probably a lot more details and better ideas out there. You may also want to look over on YouTube because there are a lot of videos for template solutions.

Good luck!

We'd need a little more clarity on your criteria.

What constitutes a "minimal" ditch?

How are you determining the elevation of the top of the ditch fill (the green and pink solid lines)?  Your section with the green doesn't fill the ditch completely.  Is there a reason for that or because it's just a sketch?  Is the ditch fill a different material?  Does it need to catch on the road side of the ditch?

In your lower sketch, is there a reason you're going beyond the 100' limit?  It would seem to me you might be able to adjust the slope to catch the ground at 100' rather than extend on the 5:1 slope.

Would it be possible to start at the 100' work limit and come back toward the road on a specified slope (you mention 1%) and catch the roadway embankment on that slope?

Do you have an example of what this would look like? I had one that was almost right but it wouldn't stop where I needed it to or it kept running underground. Getting the seek points is where I was having a problem I think.

I don't even need the 1% slope I suppose, we were using 470 as the flat elevation. the ditch isn't filled because of this. I was trying to run a fill template first off that 100' mark and still couldn't get it to run right. The ground varies so much in this area that's the reason for it not filling all the way to the top and id rather hold an elevation, at the edge, we are stopping the flat at 100' so the slope off is just the way it would fall is what's being demonstrated there.

If your 100' isn't variable at all, you could just define a construction line based on two points - one at your 100' X distance and y equal to the PG, and another with X equal to the first point and "Project to active terrain". You could try it with just the point on active terrain, but I like construction lines so I can see things more easily.

Unfortunately, I'm not going to be able to get you an example any time soon. Deadlines, y'know?

Here is one video from CivilTSG on Youtube that might be helpful. They actually have quite the library and I've learned a lot from them. Here's Another one that's not quite what you're looking for, but might spark an inspiration.
