Enhancements Included in This Update

The following enhancements have been included in the Autodesk AutoCAD Civil 3D 2018.3 Update:

Design Efficiency Updates

You can now specify the maximum rate of change for the superelevation cross slope of an alignment in the Edit Feature Settings – Alignment dialog box.

Production Efficiency Updates

Data shortcut synchronization related to superelevation and cant changes has been enhanced. With this enhancement, changes to more types of superelevation or cant parameters in a source alignment will prompt you to synchronize a data referenced alignment.
You can use a new system variable named SyncDrefPsetToSource to control whether property sets are synchronized when you synchronize data shortcut references. You can use the following settings for SyncDrefPsetToSource:
- 0: Property sets will never be synchronized when related data referenced objects are synchronized.
- 1: Property sets will be synchronized when related data referenced objects are synchronized.

Collaboration Efficiency Updates

You can use a new option in the Export Settings dialog box to specify whether to convert feature lines, parcel segments, and survey figures to 2D polylines or to 3D polylines when exporting a drawing with the Export Civil 3D Drawing command.

Note: For information about additional updates to the Export Civil 3D Drawing command, see Primary Issues Resolved by This Update.
