Select your alignment, then select the profile you wish to dynamically link to.
From the Home tab > Create Design panel > Feature Line drop-down > Create Feature Lines f rom AlignmentĢ. In this case I chose to use my FG profile as the feature to extract a feature line f rom (We will keep both crowns maintained).ġ. I first start with extracting the centerline feature lines as a dynamic link to either my profile or corridor. Let’s take a 4-way intersection for example. Sometimes you need just a bit more control, and feature lines will allow you to do so. Yes, we could use the intersection tool to create this, but sometimes that just does not accomplish what we want it to do. Below is a screenshot of what I will be using:

This will typically be a simple assembly and can even be a copy/modification of your corridors full assembly. We will use this assembly for both examples.
We will need to create an assembly for our curb & gutter. You can choose to add them to a site, or now use the “Siteless” feature line options. Select the settings option to choose whether or not to dynamically link them to the corridor.

Many people use feature lines for intersections, but up until now it was more of a manual process and not very dynamic. But now you can add the feature line to a corridor along with a curb & gutter assembly and have a much more dynamic and accurate surface.Īn intersection is also a great example of using feature lines within your corridor model. I then use the stepped offset command to give me flow line and/or back of curb elevations, and sometimes I may use grading objects to keep some level of dynamics. When I design a parking lot, I typically design the edge of pavement in order to see true slopes of asphalt. Feature lines can also be selected when creating the corridor and when adding baselines.Ī parking lot is a good example of where to apply this new workflow. In addition to alignments and profiles, feature lines now can be used as corridor baselines. If you would like the data used for this article, please email me and I will send the files. This article helps you walk through a couple scenarios of when you could possibly use feature lines in your corridor modeling. But even for those doing “simple” site plans and subdivision roads, Civil 3D has a great way to increase your productivity and help streamline your workflows.
Much of this is because of Department of Transportation’s getting deeper into Civil 3D workflows and larger companies pushing for things to behave a certain way. Over the past few releases of AutoCAD Civil 3D there has been a lot of emphasis on Corridor modeling, corridor modeling techniques and advanced modeling workflows.
