Corridor Question

[ChanningMcRae]

I've attached an image of my situation. It's a rail spur addition to an industrial site.

I'm using an alignment (the top long black line) and a corridor to model the rail and ditch, sloping to existing after the ditch. This works fine for the area between the green arrows.

In fact i can probably also easily model the other rail spur (shorter black line on bottom) and ditch with another corridor and alignment.

But how do I model a sort of storage area/ditch along the end of the rail spur, sort of a rounded endcap to the drainage area.

I know I can do this with features lines quite easily, but is there a good way to do it with corridors?

You could use a quazi-cul-de-sac method. Make a new
alignment/profile/baseline around the end cap.. I would probably just do it
with feature lines / grading instead to be honest. It'a a little easier if
you're not sure about the quazi cul-de-sac methid.

Yeah I think grading will be the quickest for me. Not as easily editable as a profile and I usually try to avoid grading as I rarely crash without it, but the grade to surface criteria is great.

I think it would depend on if you want to keep that area with the corridor model or just add it to the surface after the corridor is built. Most of the time I just attach the information to the surface.

I plan to paste the corridor into a copy of the existing ground surface because the most important part of this one is how it interacts with the existing surface.
