Autodesk Civil 3D 2021

Pressure Pipe Network Improvements

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.

Collaboration and Interop Updates

Corridor Workflows

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.

Bridges Workflows

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

Other Data Exchange Updates

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.

Collaboration for Civil 3D

• 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
