Learn how to build corridors in Civil 3D software, with a keen focus on creating an assembly to form the basis of your corridor along your chosen alignment and profile. This guide offers a step-by-step explanation on how to utilize common assemblies from the tool pallets within Civil 3D to form your corridor.
Key Insights
- The process of building corridors in Civil 3D begins with creating an assembly, which is used to structure the corridor along your alignment and profile.
- Tool pallets within Civil 3D provide different tabs comprising various pieces and parts of assemblies that can be used to create your corridor. These include common assemblies, basic sub-assemblies, lane, shoulder and median sub-assemblies, curbs, generic sub-assemblies, and conditional sub-assemblies, among others.
- Using the common assemblies from the tool pallets eliminates the need to place an assembly baseline, as they already have the baseline placed into the drawing. This makes the process simpler, although some may prefer to build their corridor from scratch to understand all components involved.
Note: These materials offer prospective students a preview of how our classes are structured. Students enrolled in this course will receive access to the full set of materials, including video lectures, project-based assignments, and instructor feedback.
So in this video, we're going to start talking about doing corridors inside of Civil 3D. The first part of creating a corridor inside of Civil 3D is actually creating an assembly that will be used to build that corridor along your alignment and your profile.
So what we're going to do in this video is we're going to place a common assembly based on the tool pallets that are inside Civil 3D. So to do that, we first have to pull up the tool pallets. So to get to the tool pallets, we're going to navigate up into this pallet section of the ribbon bar at the home tab.
And this button right here is the tool pallets button. When we click this button here, the tool pallets window opens up. And so what's inside of the tool pallets window is different tabs with different pieces and parts of assemblies that we can create.
We have the common assemblies and intersections. Then we have basic sub-assemblies. So the sub-assemblies are what's used to create more complex assemblies.
Then we have lane sub-assemblies, shoulder sub-assemblies, medians, curbs, the way that you can daylight off of the edge of a road. You have generic sub-assemblies, conditional sub-assemblies. You have trenches, retaining walls.

We have rehab sub-assemblies. And then you have additional sub-assemblies that show up down here. So what aren't being displayed is the new rehab bridge and rail sub-assemblies.
So what we're going to go ahead and do first is we're going to place a common assembly. So normally when you're dealing with sub-assemblies, you have to go up and place an assembly baseline by dropping down and selecting create assembly. But with these common assemblies, they already have the baseline placed into the drawing.
We can just go ahead and select one of them and then place it in the drawing. I don't prefer to use these common assemblies because I like to work with what I know I'm going to be building and then choose the individual parts to build it out. But in case you wanted to use one of these common assemblies, it's very simple.
You just select which one you want to place. I'm going to place a basic assembly. You just click it.
Civil 3D will give you some information about what that basic assembly is going to have. And you're prompted to specify a location for the assembly. I'm going to go ahead and navigate over to where my table is here because I don't want to place this assembly with any of the other objects that are inside of my drawing.
So I'm going to go ahead and place it up here above this table. I'm going to navigate down here. And when I zoom in, you can see underneath my cursor, there's this red line with a crosshair that is the center for my assembly.
I'm going to go ahead and click somewhere on the screen and Civil 3D is going to build me an assembly. And so what this assembly is, is it is basically a typical cross section for my roadway. So what we have here is we have a lane, a curb, maybe some landscape, a sidewalk, a little bit more of some landscape or a shoulder, and then our cut or fill condition for daylighting to a surface.
So what I'm going to go ahead and do is I'm going to do a save as on this drawing, and then I'll meet you in the next video. I'm going to go up here and do file, save as. I'm going to go to my working folder.
I'm going to change my name from Civ202Prof to Civ202Core because we're working in corridors now. I'm going to go ahead and click save. And now that my name's changed up at the top, I'll meet you in the next video.
