What's new in ArcGIS for AutoCAD 420

[DanWade]

New functionality

• Civil 3D COGO points are recognized as point feature geometries for web features and document feature layers.
• You can modify existing point features to COGO points using the Assign Default Symbol user interface if working within AutoCAD Civil 3D.
• You can import an Autodesk Geodata ESPG number to assign the Esri coordinate system definition using the Coordinate System user interface or the Esri_CoordinateSystem command.
• Enhanced attachments support now includes the ability to add and remove attachments on supported web feature layers.
• Support for GUID type fields has been added, which includes global ID fields.
• Expanded support for property fields includes Angle/Rotation and the textValue of annotation features.

User interface changes

• New symbol setting options have been added to the Assign Default Symbol user interface to accommodate COGO points and the redrawing of symbols according to user settings.
• New Redraw context menu option for point feature layers to redraw point symbols based on the current point symbol settings.
• New integrated web help and AutoLISP documentation formatting.
• The Attachments user interface has been updated with new add and delete attachment options.
