Civil 3D 2021 is Here

It’s that time of year again folks; Autodesk has released their flagship Civil Engineering product in Civil 3D  2021.  Here is an Autodesk article explaining the new changes.  Here are my favorites from this release.

Format

There is no format change this year.  Excellent!  You may share your Civil 3D files with users back to 2018.

Pressure Networks

There has been significant development to this feature.  If you have not been using pressure networks due to feature limitations, it is time to rethink your approach; these tools are good!  We now have path-based pressure network Pipe Runs in both plan and profile.  The image below shows a grip-edit to a pressure main.  The bend was automatically swapped after the grip-edit.

Do you need your pressure network to maintain a 1.5m cover below your corridor surface?  Here, the pipes are dynamically linked to the design profile at a 1.5m depth.

Infraworks Interoperability

More collaboration features have been introduced, such as:

  • Civil 3D corridors can now be mapped to Infraworks Component Roads and remain dynamic to the drawing when reimported.
  • Infraworks bridges are now supported within Civil 3D, stylized labeled in profile views.  There is a new Bridges node in the Prospector.

Scripting

There are additional nodes and functionality related to Dynamo scripting.
