I'm working on a complex urban road with many median breaks, driveway enterances, swales, shoulders, curbs, and berms. I broke my corridor into two peices the "left side" and the "right side" so that I dont have to create a new template everytime i lose a berm or gain a swale or have a side street. I am having trouble creating a median now. Attached are some of the assemblies.
The other problem I'm having is that Civil 3d doesn't do a good job when the turn lanes cross the Center Line. How do you fix this?
Civil 3D does a GREAT job when turn lanes cross the center...

While that post is very informative and I thank you for the time it doesn't fully address my problem. I am using an assembly for the left side and a different one for the right side at turn lanes. The problem is that while the PGLs are the same the Edge of pavements are different at the turn lanes. I'm having trouble even faking it in. And attachd is what i'm talking about with 3D having trouble crossing the Center Line. Notice how the corridor lines will not follow the EOP across the CL
I understand. I was hoping you'd try using the median subassemblies and
marked points as discussed in an effort to resolve your issue(s). I
initially wrote the article for a client working with a very complex
corridor - much like the one you are constructing...

You can save some pour soul with dial-up a lot of time if you would send in
a .png in lieu of .bmp. Notice the size difference.

I'm also trying to build a complex roadway, and I'm having trouble using the medians. When you insert a median on the baseline of an assembly, it doesn't use the baseline as the center! Is there some trick I'm missing??? And if you use just basic links, how can you effectively use transition lanes to build the full crested roadway on the left (3-lane, southbound) and the full crested roadway on the right (3-lane, northbound)??
Thanks,

I'm trying to design this road w/ a median in the middle (first time trying it) and I can't seem to figure it out...I'm not fully understanding how these median assemblies work.
I followed the post by Scott - it was informative, but unfortunately I'm still having issues.
I have created an alignment for both the right and left sides of the median and an alignment for the 2 outside EPs. Created assemblies as shown in the post, added lanetaperfrommedian to them, and set the targets in the corridor accordingly.
I think the issue I'm having is which alignment needs to be used for my Baseline in the corridor. I created a CL alignment through the middle of the road/median and profiled it. When I put the corridor together, the roads went to the EP, and it created a median, but crazy contours running through the median.
Will someone please explain to me what horizontal alignments I need to be creating along w/ the assembly.
If you're seeing crazy contours that is normal for this subassembly. When
creating your corridor surface you are probvably using Top links to define
it? This is the problem with some subassemblies. Instead, use feature
lines and select all of the ones you need. ETX, Flowline_Gutter...all the
ones that are on the top of your assembly.
I assume you've seen Chakri's webcast.

The feature lines thing should fix the contours assuming you're doing
everything else correctly.
I'm just getting started on this topic, but I had a quick question. Will the assembly still pull the elevations from the centerline/baseline profile? What subassembly entity will it use as the elevation/insertion point?
