Autodesk officially released Autodesk Civil 3D 2021 and the many related Autodesk Civil interoperability and Civil product development tools. All the Civil 3D 2021 help files and resources are live.

Autodesk Subscription customers should be able to download the product from the Autodesk Subscription Center.

Autodesk Civil 3D Free trials and install resources are also available via the Ask Ava app.
You will need to employ the latest Autodesk Virtual Agent beta.
Usually it is preferred to employ the Autodesk Download Manager.

Autodesk Civil 3D 2021

The latest Civil 3D 2021 includes long awaited Pressure Pipe Network support for Pipe Runs and many Pressure Pipe interface improvements. Hoorah!


Pressure Pipe Layout and Edit in Civil 3D 2021

New and enhanced pressure network commands to create and edit path-based pressure networks.

  • Add path-based pressure network pipe runs by selecting locations to define the path, or by selecting existing objects or parts in the drawing.
    When you grip edit pipe runs to change their locations and update the pressure network path, the parts remain connected and the fittings are updated using available part sizes in the current parts list.
  • When creating a pipe run, you can optionally create a surface profile for the pipe run to follow.
  • Add bends automatically when creating pipe runs.
  • Add branch fittings to create intersecting pipe runs, automatically using the nearest fitting size from the current parts list.
  • Add and remove bends, automatically adding or removing points of intersection and fittings.
  • Break or merge pipe runs.
  • Use the new Pipe Run Profile Settings dialog box to control how a pipe run follows a surface or a surface Profile and to add the pressure network to a new or existing Profile View.

Corridor Collaboration Improvements

Corridor Collaboration Workflows between Civil 3D 2021 and Infraworks 2021 received a lot of attention.


New Corridor Interoperabilty for 2021

Interoperability between Civil 3D and InfraWorks for corridors has been enhanced.

  • You can now create corridor component roads in InfraWorks from Civil 3D corridors.
    A corridor component road represents the designed corridor in Civil 3D and is read-only in InfraWorks.
  • When you bring a Civil 3D corridor into InfraWorks as a corridor component road, geometry for the shapes and links is created in the InfraWorks model.
    You can use the Component Mapping dialog box in InfraWorks to specify how the shapes and links are mapped to materials.
  • Options are now available in the Refine Selection Set dialog box to select InfraWorks tunnels and generic objects.
    InfraWorks tunnels are now brought into Civil 3D as mesh objects.
    Property set data is now created in Civil 3D for InfraWorks tunnels and generic objects.

Bridge Collaboration Improvements

Enhanced and improved Bridges workflows between Civil 3D and InfraWorks to add bridges to your corridor designs.

Enhanced Bridge Workflows for 2021

If the bridges are changed and republished from InfraWorks, you can reload them into your drawing.

  • A roadway designer can design an alignment or a corridor in Civil 3D and then a bridge designer can bring the alignment or corridor into InfraWorks and add a bridge.
    When the bridge is completed in InfraWorks, the bridge designer can publish the bridge to an IMX dataset which the road designer can bring into Civil 3D.
  • When you open an InfraWorks dataset in Civil 3D that contains bridges, bridge objects are created in the drawing.
  • The appearance of bridges in plan view is controlled using the Bridges to Civil 3D layer settings, which you can set up from the Configure InfraWorks - Civil 3D Exchange Settings dialog box.
  • You can project bridges to a Profile View to create general arrangement for a sheets.
    When projected to profile views, the appearance of the bridges is controlled using bridge projection styles.
  • If the bridge dataset is republished from InfraWorks, a message will be displayed in Civil 3D and you can reload the dataset into your drawing.

Publish to ArcGIS Updates

  • The Publish to ArcGIS command and the Export to FGDB command now include the ability to output object properties as ArcGIS attribute information.
  • Project data for use with Autodesk Collaboration for Civil 3D can be stored on the Europe data center.

Other Improvements

  • The installation for Dynamo for Autodesk Civil 3D is now integrated into the installation for Civil 3D.
  • Support for the Oregon Coordinate Reference System (OCRS) has been added

Framework for Civil 3D 2021 Upgrade Protection

We guarantee that a Framework for Civil 3D product for one release of Civil 3D will upgrade to the next Release and every Update. This demonstrably works for our civil engineering, survey, and public agency customers large to small.

If you purchase a new copy or upgrade to any latest flavor of Jump Kit Release 8 for Civil 3D 2020 between April 15, 2020 and the official Jump Kit Release 8 for Civil 3D 2021 release date, we’ll give you a free Upgrade to that flavor of Jump Kit Release 8 for Civil 3D 2021 when that product is available.
