New Features & Enhancements in Civil 3D 2018.2

The release of Civil 3D 2018.2 this week brings with it many updates that may have some welcome additions for many users. Autodesk has organized these features into three categories: design efficiency, production efficiency, and collaboration and data exchange. Read on for more information about what’s new!

Design Efficiency Updates

This category has updates in profiles, railway, subassemblies, and pressure network content. Let’s discuss profiles first. There are 2 updates for profiles.

The first one to talk about is the Profile Layout Direction. This command simply allows for profile creation to be done now in a right to left manner. Remember that the previous method only allowed profiles to be created from left to right. Figure 1  on the right shows an example of creating a profile from right to left.

The next enhancement to profiles in 2018.2 is vertical curves in offset profile slope transition regions. So, what does that mean? Basically, this is a new behavior for vertical curves that are in offset profiles. The enhancement is that vertical curves in offset profiles are now created in what is called slope transition regions. The previous functionality would create tangent segments in slope transitions instead of creating vertical curves. Figure 2 on the left (source: Autodesk) shows an example of slope transition regions.

Moving on from profiles, there are also railway enhancements in the form of a couple of new command functions that allow you to create and edit rail turnouts and crossovers using these new commands.


Next up in this category is subassemblies. We are not talking about one or two new subassemblies here. Autodesk has added over 60 new subassemblies in Civil 3D 2018.2! There are many new subassemblies that I believe will give users great new functionality without having to go through the process of creating custom subassemblies. This list ranges from curbs, to agency or region-specific subassemblies (such as Caltrans and Clark County), and even valley gutters! For a complete listing of these new subassemblies, check out the article on the Autodesk Knowledge Network.

The last update in the Design Efficiency category is the addition of new pressure network content for both metric and imperial units. These additions include air valves, hydrants for above and below ground, and various other pressure network parts.

Production Efficiency Updates

In the Production Efficiency category, the biggest update is controlling the way that you can show 3D solid crossings in section views. This new functionality allows you to control how 3D solid crossings look by changing the layer properties. For example, as stated by Autodesk, “the color of a 3D solid crossing that uses the <Section> option is now controlled by the color of the layer associated with the 3D solid rather than by the projection style associated with the solid.” Figure 3 below from the Autodesk website shows an example of this.

The other updated functionality is the ability to select multiple objects when you want to select or specify settings for your projections and crossings. Here, you have control over things like styles or elevations settings for multiple objects. This could give you some great output that previously was not so easily available.

Collaboration and Data Exchange Updates

The last category for the 2018.2 update is Collaboration and Data Exchange. There is essentially one element in this category, and this element could be huge for some users. This is the Autodesk Civil Engineering Data Translator. Now, I know you may be thinking that this is not a new thing—but it is new in Civil 3D 2018. For those who are not aware of this functionality, the translator makes it possible to export Civil 3D drawings into a format that can be imported into Bentley GEOPAK and Bentley InRoads. You can also translate data from those products into data that can be imported into Civil 3D.

And that is it for the updates for Civil 3D 2018.2! As you can see this update is largely about new content added into Civil 3D around the subassemblies and pressure network parts. Check it out and if you have any questions, please feel free to contact us. Enjoy your holidays and we will see you in 2018!
