Streamline tasks, maintain consistent data and respond to changes quickly.

What’s New in Civil 3D 2021

Bridge design interoperability
Link your bridge model between InfraWorks and Civil 3D.

Pressure network
Enjoy greater design flexibility and efficiency with pressure pipe layout and editing.

Dynamo Player
Easily locate and run Dynamo scripts directly in Civil 3D. Create and share scripts for design automation tasks.

Previous Release Features

Collaboration for Civil 3D
Manage the exchange of design data, visualize changes, track project progress, and manage issues in a cloud-based single source of truth.

BIM 360 project creation
Set up project teams, add members, set user permissions, and more.

Connect to BIM 360 Design
Add a Civil 3D file to a BIM 360 project. Connect to BIM 360 through the Desktop Connector.

Connector for ArcGIS
Bring ArcGIS data into your Civil 3D drawings, update features as needed, then save back or publish that data for use in ArcGIS.

Dynamo for Civil 3D
Use Dynamo for programming and design automation. Define scripts and routines in a visual environment to design and expedite workflows.

Rail and centerline exports
Generate rail lines based on specified tolerance or interval and that dynamically adjust to modifications to the parent rail alignment, profile, and cant.

Storm and sanitary analysis
Set individual tailwater conditions for each designed storm, use dimensionless Hydrographs per sub-basin, and use new storage chambers by ADS.

Gravity network analysis
Use the updated Analyze Gravity Network dialog to analyze a pipe network and apply the results.

BIM 360 File Locking for AutoCAD
Automatically lock and unlock for DWG and DWT files that are stored in BIM 360 when they are opened in AutoCAD.
