I have two feature lines I want to grade towards each other at different grades until they meet. Is this possible, and if so, how? Thanks.
I'd be impressed to see that, Fred. the OP never said, but is the 4:1 radial to bottom stream line or to the 4:1 contour at the top. Call me pesemistic. Either way I see a train wreck in those coves; even with pencil and paper 🙂
Been away for a bit but came back to some great stuff! Thanks for all the posts. I'll start trying some different things and see what works. Chances are we'll end up in a different direction when it's all said and done. Thanks again!
Another approach is to use gradings to create a surface "pan" @10:1 slope from the centerline wide enough to overlap the edge lines, then target the pan surface with 4:1 gradings from the edges. The 4:1 gradings will be the sides the pond. Lastly, close the ends of the pond and add infills between the centerline and the 4:1 gradings to complete the model.
Incomplete example (2013) attached.
By the way, the projected 10:1 bottom ends up higher than the edges of the pond.
Ideally a grading should miter and handle the coves as seen in untitled1.png. One issue I have with the data for this is that this grading breaks down if you try to model it all in one or even two gradings on two sites. The other issue is that I do not believe the 10:1 and the 4:1 slope will intersect all all. See untitled2.png.

According to the OP's earlier post, the 10:1 projects downward from the pond CL FL creating a W shape in the finished grading
Your drawing demonstrates exactly what I've said from the beginning: the 4:1 fron the top of the pond wont work
The centerline is the channel of a creek running through a golf course, it is dammed at the northerly end to form a pond currently. The lake edges are the proposed shaping. The idea is to grade up at 10:1 from the channel and down 4:1 from the bank and intersect. Does that help clarify? I think the poster who mentioned the 4:1 has to come up at some point to merge w/ the channel projection has it right. Isn't looking like that plan will work.
