New Features

Corridors

• The process for extracting solids from corridors has been enhanced. New options are available for selecting the corridor areas to extract within corridor regions, station ranges, or closed polygonal areas. When created in the same drawing as the corridor or corridor reference, the solids can now be created with a dynamic link to the corridor so they update when the corridor is updated. A Property Data page is now included in the wizard which you can use to automatically associate property data with the solids, such as corridor name, region name, and code name. For more information, see To Extract Corridor Solids.
• In addition to alignments and profiles, you can now use feature lines as corridor baselines. You can select the feature lines when creating the corridor and when adding baselines. The feature lines that you can use can be created from the feature line creation tools. Corridor feature lines cannot be used directly but can be used if extracted from the corridor.
• An option is now provided for controlling whether corridor feature lines can cross a baseline. For example, in certain situations, such as with a divided highway, part of a corridor design may need to cross the centerline and this can require that the corresponding feature lines also cross the centerline.
• Where corridor tangents intersect at a corner, and where the corridor is created at a fixed width, the inner and outer corners of corridors are cleaned up automatically. For more information, see About Corner Cleanup for Corridors.

Data Shortcuts

• You can now create data shortcuts for corridors so you can reference them into other drawings. When you create a data shortcut for a corridor, shortcuts are also created for the alignments and profiles that make up the corridor baselines. If corridor baselines are comprised of feature lines, shortcuts are not created independently for those feature lines. For more information, see To Work With Data Shortcuts and To Create Corridor References.
• You can now save the geometry of a reference surface in the drawing that contains the data shortcut reference. If you choose to save the geometry of a reference surface in the drawing, the drawing that contains the reference will become larger, but will open more quickly unless the source surface has changed. For more information, see To Work With Surface References.
• You can now create multiple data shortcut references at once, by either right-clicking the data shortcuts and selecting the Create Reference command, or by selecting them and dragging them into the drawing. This functionality is available from the Data Shortcuts collection in Prospector and in the Data Shortcut Manager dialog box. For more information, see To Work With Data Shortcut References and To Manage Data Shortcuts.
• You can now control whether notifications appear at the drawing status bar when data shortcut references are out of date and need to be synchronized. For more information, see To Synchronize a Reference Object.

External Style Management

• You can now keep styles in your drawing synchronized with the styles in external reference templates. Reference templates simplify the management of your drawing styles and keep them up to date.

Object and Data Shortcut Subfolders

• You can now create subfolders within Prospector and the Data Shortcut Manager. Right-click an object collection or a data shortcut collection and click Create Folder. You can drag-and-drop existing objects into the new folders, and you can place folders inside other folders. When you create references to data shortcuts that are stored in subfolders, the subfolder structure is replicated in the consumer drawing. For more information, see To Manage Data Shortcuts and About the Toolspace Prospector Tab.

Pressure Network Content

The following new pressure network catalogs are included.

For more information on specifying a pressure network catalog, see To Specify the Pressure Network Catalog.

Roundabouts

• The roundabout-related features from Autodesk® Vehicle Tracking have been integrated into AutoCAD Civil 3D. These commands create a new type of roundabout object. For more information, see About Roundabouts.
• You can now bring roundabouts into an AutoCAD Civil 3D drawing from Autodesk® InfraWorks® 360. For more information, see About Exchanging Data Between AutoCAD Civil 3D and Autodesk InfraWorks 360.

Spiral Support

• Support has been added for a new spiral type, New South Wales (NSW) Cubic Spiral. For more information, see About Spiral Definitions.

Autodesk Vault

• You can now add corridors to Autodesk Vault projects. Alignments and profiles which are used as the corridor baselines are also added to a project when you add the corridor.
