MULTIPLE INTERSECTIONS

[Manuel_Jinés]

Good afternoon friends,
 
I recently started working with intersections, due to my little experience or none at all in this topic, 
I was somewhat involved in performing them and for that reason I would like to have opinions 
on how to work some multiple intersections.

1.- In this case I think that I am doing well.


2.- The doubts are generated when wanting to work the following intersections:

Thank you in advance for your contributions on this topic.

Those are complicated intersections and will not be solved by Civil 3D Intersections. Within your Corridor, you will need to use multiple Baselines, Regions, and Targets to accomplish your goal. Modern versions of Civil 3D, 2018 and 2019, allow you to use Feature Lines as Corridor Baselines. That should streamline your process somewhat.

Also, look into Connected Alignments, a way to make returns blend between two controlling alignments.

Here's a primer on the concept of manually creating intersections. This is from 2014 and does not include information on Feature Lines as Baseline nor Connected Alignments:
