Say hello to InfraWorks and Civil 3D 2020

Original article by Tim Yarris and Nick Zeeben from Autodesk can be found here.


The highly anticipated releases of InfraWorks and Civil 3D are here. Product managers Nick Zeeben and Tim Yarris share the latest features and enhancements.


Civil 3D software is a civil engineering design and documentation solution that supports Building Information Modeling (BIM) workflows. Improve project delivery, maintain consistent data, and respond faster to design changes.


This release of Civil 3D delivers further improvements to performance and scalability, enhancing BIM design and production efficiencies for larger, more complex projects. The latest release is packed with new features and we’re particularly excited to introduce Dynamo for Civil 3D, which will streamline repetitive tasks and help you get more out of your model.


With Dynamo for Civil 3D we enter the next era of design automation and computational BIM. Customers will be able to iterate, automate and solve complex design challenges, significantly reducing time and improving quality. You can get started with the included sample scripts or use the visual programming environment to develop custom scripts to tackle your specific tasks. Accelerate design efficiencies with Dynamo for Civil 3D and the new features in Civil 3D 2020. Watch Dynamo in action below:

Engineers at Belgium’s TUC Rail , a railway infrastructure manager, are already incorporating the system for their own uses with great success.


“Dynamo gives me the means to be more flexible and quick in solution adoption. In my experience we hope that civil projects are standard, but every time you find that you need something a bit different. With the right nodes it will be easier to create a variation and test something new.


I also look forward to drafters use this tool. This is simply next level scripting with not just AutoCAD, not just Civil 3D, but geometry and data as a whole. As a programmer I am very happy with the visual engine of Dynamo to support programming with geometry.

The possibility of manipulating AutoCAD and civil geometry at the same time is one of the big advantages compared to AutoCAD lisp ( I already manipulate both with the API, but this is quicker).” –Wouter Bulens, TUC RAIL


Ready to try Dynamo for Civil 3D? New customers can start a 30-day free trial of Civil 3D. Current Civil 3D and AEC Collection subscribers can download Civil 3D 2020 through the Autodesk Desktop App or from your Autodesk Account. **Please note that Dynamo for Civil 3D is available as a separate installation through the Autodesk Desktop App and from your Autodesk Account.


New look and new capabilities


In addition to the introduction of Dynamo for Civil 3D, the 2020 version of Civil 3D also comes with notable enhancements to storm and sanitary analysis, gravity network analysis, and an upgraded user interface.


Updated User Interface

The first thing you may notice when launching Civil 3D 2020 is the look and feel – a dark blue theme running across the ribbon background, and easier navigation; these cosmetic updates were designed to create a uniform experience across the entire AEC Collection. The kicker – upgrades to the ribbon icons in order to scale with high-resolution monitors such as a 4K display, helping to make the purpose of each command clear and intuitive.


Storm and Sanitary Analysis

There are several updated features in Autodesk Storm and Sanitary Analysis, which accompanies Civil 3D 2020. When analyzing multiple storm events, you can now add separate tailwater conditions for each event and edit the outfall conditions for each storm event.


When using dimensionless hydrographs, you can now adjust the peak rate factor for the hydrograph on a per sub-basin basis. For example, if you’re running an SCS hydrology model, TR20 or TR55, the sub-basin dialog box enables a new peak rate factor field at the top of the dialogue box and for each sub-basin in the table at the bottom of the dialogue box. The factor can be entered on either location and copied from one sub-basin to another. New storage chamber systems from ADS or Cultec are available for underground attention.


Gravity Network Analysis

The updated analyze gravity network command helps users to analyze a gravity pipe network and then apply the results while in the model. This feature uses the hydraulic properties and gutter details for each structure being analyzed in this network. The wizard for the analyze gravity network command has been replaced with a mode-less dialogue box, which enables you to directly interact inside the drawing. There are three different types of analysis to choose from: pipe sizing, computing energy in hydraulic grade lines, and inlet analysis.
