ditch intersection in an interchange

hy,

 

I need some help in creating an intersction between 2 ditchies like in the pictures attached.

I have created an ansembly, but its not dynamic, i have 3-4 polyline on top to put the targets for the ditch. Maybe the intersection like will change and so on.because i need to modify the width of the lane.. and so on.. Also i have created a grid, i couldnt creat the daylight intersction to existing ground between the 2 assemblies. The daylight of each assembly should stop if they meet.

In the other picture i have put interchange in wich i want to use that assembly... its a linkroad that has a ditch and intersects with the motorway that also has a ditch.

 

I can not attached the dwg file it is to big to be attached here.

 

Also there is on option of creating a subansembly in subansembly composer.

 

Thanks.

 

I am using civil 3d - 2013...

Thank you to discuss this topic!

I worked on a similar project, and I'm looking how to manage the intersaction slope area of the principale section with the ramp.

There is a LinkSLOPEBETWEENPOINTS subassembly in the tool palette that may be of help to you in this case.

Take a look at this thread:

It appears that @fcernst has figured out a way to achieve this using the subassembly composer. maybe he can share his technique with the rest of us.

Thank you for your ideas Smiley Indifferent
I found the following solution:
1- Create Surface from Baseline 1
2- Create a fetureline form the area of Baseline 1 That Located in the corridor intersection entre 1 & 2
3- Create subassembly That target featureline by using linkoffsetandelevation

This is not the only one, but it did the trick for me.

Thank you.
