Enhancements

The Civil 3D 2024.1 Update is a major update to Civil 3D that includes significant enhancements.

Corridor Workflows

Significant improvements to the creation, edit, and maintenance of Corridor Transitions includes new Transition Tolerance Gap property and the ability to Copy and Paste Transitions.

Project Explorer

A new Subassembly tab in Project Explorer with improved edit and reporting support for subassemblies.

Surface Workflows

New Civil 3D typed commands to add common data to Surface definitions directly from the command line.

Gravity Networks

Pipes can now connect to Structures in other gravity Pipe Networks.

There are new Text For Each Label Style components for Profile View Band Labels for Structures.

There are new Text For Each Label Style components to add Property Set data for connected Pipes and Pressure Pipes in Structure Labels.

Pressure Networks

Significant improvements to Pressure Pipe Run editing and stability that includes:

• The capability to move and rotate pressure pipe runs using the AutoCAD MOVE and ROTATE commands without detaching from their underlying pipe run alignments
• Automatically swap between a tee and a wye Fittings if the Parts are available in the Network Parts List
• The reference alignment of the adjacent pipe is now automatically used when adding new parts to a pipe run.

Improved support for Connected Pressure Pipe annotation that includes:

• Label and stagger the data for connected Pressure Pipes in the Profile View Band labels for Fittings and Appurtenances.
• Add Property Set data for connected Pipes and Pressure Pipes in Fitting and Appurtenance Labels

Subassembly Workflows

Directly import Subassembly Composer PKT files by Right Click in the Prospector

New Right Click menus support to Create New subassembly instances or Change Subassembly PKT references in the Subassembly collection in the Propector tab

A new Other Subassemblies node in the Subassemblies collection in the in the Propector tab that displays the Civil 3D stock .Net based code subassemblies.

A new Subassembly tab in Project Explorer with improved edit and reporting support for subassemblies.

Improved Event View support for Subassembly warning messages during Corridor creation and rebuilds.

ArcGIS Workflows

A new capability to modify and update AutoCAD objects and save back the changes to ArcGIS. Move AutoCAD points, polylines, and polygons to an ArcGIS layer and then save back the newly added objects.

Improved support for arcs:

• Arcs on a polyline layer stored in ArcGIS are imported into Civil 3D as true arcs for all supported features.
• You can move new AutoCAD or Civil entities with arc segments to imported ArcGIS layers in Civil 3D and save them back to ArcGIS with the arcs kept instead of tessellated.
• You can refresh ArcGIS layers with arcs and preserve the arcs.

Improved the performance of refresh updates from ArcGIS and save back changes to ArcGIS.

ArcGIS domain values are now imported as a List type property set rather than as a read-only string type so that you can update the domain value list from both Civil 3D and ArcGIS and keep it synchronized when refreshing and saving back.

The default feature type to be imported into ArcGIS for each layer is now cached after it is specified, so the next time the layer is imported in the same session it can be imported with the latest feature type that was specified.

The layers are shown in alphabetical order in the Autodesk Connector for ArcGIS so that you can find a specific layer more easily.

Rail Workflows

Ability to add Cant specific properties to Spiral and Tangents segments in a Rail Alignment

Fixed Issues
