Cooridor Targets

[StephenP9]

In the attachment you can see I have three cooridors created. One for my main road and two for my curb returns leading into my parking lot. Can anybody give some insight on how to tagets these cooridors too the two YELLOW lines I have highlights? I want these curb returns to tie in nicely with my other cooridor and parking lot.

Thank you,

I think you were on the right track in your other thread by using the Intersection Wizard and Steve explained HOW to use the wizard.

Yes Steve explained creating alignments for my curb returns and creating cooridors out of them as I did. What I am stuck on is triming the cooridors to tie in with primary road cooridor and my parking lot. I need extract the edge of pavement feature lines from my cooridor and parking lot and have the entrance cooirdors target those to make all this work together. Exactly how to go about targeting the feature lines is where i'm having a problem.

To further explain the issue i am having,

First - I created A proposed Rd. (Worked out great)

Second - I created two curb return alignments tying into the right elevations of my proposed cooridor and parking lot.

Now, the cooridors I created for my curb returns have one region each. I have a centerline alignment for the entrance of my parking lot and extracted the feature lines that are the edge of pavement.

I'm stuck on what will target what in order to have clean transitions from my proposed road to my proposed parking lot?

Steve didn't say to create 3 corridors, that's contributing to your issue.  One corridor, 3 baselines (alignments).

[StephenP9]

Create alignments and design profiles for each of the returns. Your assembly for this will include a curb and daylight on one side, and a lane sub on the other side. In your corridor the lane sub will be targeted to the centerline of the entrance road, and the featureline that defines the edge of the parking lot.

Sorry as I'm self teaching myself how to use Civil 3D. From what I gathered I had to create alignments for my curb returns (done), create an assembly that will follow the alignmnets with the proper sub-assemblies (done). Than he continues to say in your cooridor the lane sub will be targeted to the centerline. Now correct me if im wrong but dont you need to create a cooridor to attach an assembly to an alignment? Which is what I have done. I thought you could create multiply cooridors and create a final surface by pasting each surface together. I thought there would be way to target a extracted feature line from another cooridor.

You're still trying to do it manually.  Start with the intersection wizard (first screenshot).  It will create a corridor for the intersection.  It will also have corridors include the baselines for the two roads.  Add regions for those two roads so that you get the coverage you need.

I created a quick example of what this would look like.  It DOES NOT use any real data so don't expect the intersection to look great.  But take note of the way the corridor contains multiple baselines.

EDIT:  also note that the wizard CREATED the curb return alignments FOR ME -- I did not create them.

in the corridor paramters , select targets. in there you can picke the targets for the requsite subassemblies, but first you have to extract the FL from the main cooridor.

I gave a basic answer last night, half expecting to come back today and answer more questions.  In the meantime everybody has piled on and apparently solved the problem.

  I love this place.
