civil 3d 2011, Are there any good tutorials or videos on creating raised median divided roads with the bull nose.
I am using one alignment and profile, the profile defines the lip of gutter of the outside lanes.
but any general videos on the topic will help.
I will toss in my two cents worth here, but others will have different opinions. I don't use an assembly with a raised median. I create my corridor as though there are no medians. I first get the design where I want it (matching existing driveways, taking drainage sumps into account, desiging intersections, etc.)
I then add the medians in as pasted surfaces as the last step. I turn the flowline of the median curb into a feature line, project it up to the corridor surface for elevations, use the feature line offset to get the back of curb, add them to a new surface ("Median 1", for example), then paste that into a new, overall surface that has the corridor surface already added.
It's simple without dealing with the complexities of corridor medians crossing over centerlines for turn lanes, etc., and it automatically includes bullnoses. Also, the number of regions is reduced as you won't have regions with medians and regions without medians to deal with. The downside is, if vertical changes to the road corridor are made, you have to reassign elevations to affected medians as they are not dynamic to the corridor. However, even with a median-driven corridor assembly, you will have to deal with feature lines for the bullnoses, so changes will still require feature line manipulation. Another downside is you will have additional surfaces to deal with to the extent that you have medians. I haven't found this to be a problem, but you should be aware of it.
I'm interested to see how others deal with corridors with medians.

Do the medians show up in sections that way?
