Default ending corridor with slope instead of open road corridor

[eugen.doberstein]

Hello,

I have a question regarding the ending of corridor with slope. The Civil 3D default corridor is ending with a open road (See attached picture). But I also want a slope in alignment direction which is also shown in the picture.

I found a 8 year old post which describes my problem - but there is a solution for a manual workaround which is laborious and timeconsuming when I have a 15000ft long alignment with 20 or more regions.

Could someone help me to find the right solution or eventually have a good idea how to solve it?

Thanks in advance

Eugen

Hi @eugen.doberstein, I tried to check your post, but it seemed to be an Open Roads post.

However, I think I understand your problem, and I have to tell you that I have done that job so far with feature lines and grading tools. To accomplish this, you manually create the feature line and then a grading to finally add the end surface to the top or datum surface of your corridor. You can also generate slope patterns that complement corridor slope patterns if you have them.

On the other hand, the same feature line can be added to the corridor as a new baseline and target the terrain to avoid the process I just mentioned with grading tools. It's a matter of taste.

I haven't done this process automatically until today, but the two ways to do it that I commented on are not that time-consuming. They are worth trying.

I hope this helps. Regards!

If I am understanding your question correctly....

You do this with your layout profile. That's what controls the slope of the road/corridor. As far as grading goes, make a separate region and use an assembly that has a simple LinkSlopeToSurface subassembly on each side.

I would draw a small "end cap" alignment (see below), with curves at the corners (small radius of 1m or similar), create a profile from the road corridor surface, and create a corridor with a daylight assembly, targetting the existing ground.

Hi @ecfernandez.

first of all thank you for your ideas. I know that kind of solution but looking for a automatic solution because our workflow is probably different than others.

I use this function regular with 20+ corridor sections but with a lot of moving of corridor position as well alginment changes. And then your comment with "not time-consuming" is relativ when I have to update 20+ corridor sections when just changing alginment+corridor sections back and forth until I found the optimal route.

Anyhow thanks for your reply. Do you have an other idea to find a automatic solution?

Regards

Hi @m_kingdon.

Thanks for your post. As answered to @ecfernandez my problem is the need of agile approach for fast changing of many corridor sections automatically. If everything is fixed the for sure I could do it fast and easy, but I have to handle a lot of corridor section without knowing where to start and end with my corridor sections to avoid fill section (in my example a small creek in a little valley) into the valley because we have no retaining walls, just the fill embankment before starting with bridge. (see attached pictures).

Hi @tcorey,

I didn´t get your point. With layout profile do you mean the alignment or the profile in the profile view.
