Complex, irregular urban intersections in Civil 3D

[Anonymous]

Hi, I'm new to this forum (and to Civil 3D), so this is kind of a question/presentation post; please bear with me.

I'm currently exploring Civil 3D and its capabilities for urban design and renovation in México. It has proven to be a powerful tool, but I've still managed to get stuck in several cases. The most critical, are complex urban intersections, like the one I'm attaching in this post.

Could anyone shed some light on what would be the best approach into modeling this kind of site?

A few notes: all of the corridors widths are irregular, aswell as the medians, thankfully, the site is quite planar. Currently, I've made a few attempts with no success, so, I'd say I've got the topography and the road layout, as either alignments or feature lines (I tried both approaches).

I'm attaching the images and the Civ3D file. If you require additional information I'll be happy to provide it.

Thank you.

This is a little much to write out for you. Here's a short primer on how to creating intersections manually, as corridors.

It's five-year-old info, but gives you the basic process.

Thanks @tcorey,

I actually ended up doing exactly that for some other intersections in the same project, but I didn't thought it was posible in this case, I'll give it a try. I also found an alternative, by making the corridors without the medians, and then creating the medians as independent objects, with feature lines of alignments. The only issue with this, is when I take it into Infraworks it seems to cause some problems with the model coverages.

Well I managed to do it, thank you.

I ended up not using the intersection tools at all. I just created the corridors and used feature lines or even polylines to edit the targets at each intersection and it worked perfectly. I'm attaching some screenshots to show the model in Civil 3D and in Infraworks.
