Controls the basic functionality provided by the AutoCAD link:

0 – Basic AutoCAD link features only
1 – Basic AutoCAD link features plus sheet set support (default)
2 – Basic AutoCAD link features plus plain drawing asset management support (not for use with AutoCAD P&ID or AutoCAD Plant 3D)
3 – Enable all AutoCAD link features

Controls the P&ID functionality provided by the AutoCAD link. This settings requires AutoCAD P&ID or AutoCAD Plant 3D.

0 – P&ID project features only (default)
1 – P&ID project features plus asset management support

Controls the synchronization of the folder specified for Civil3DSyncWorkingFolder:

1 – Synchronize to the local working folder (on drawing open)
2 – Synchronize to the vault (on drawing close)
4 - Ask the user before synchronization
8 - Synchronize only once per AutoCAD session

Note     If this value is missing from either registry key mentioned in the note at the beginning of this topic, then the setting with the same name on the AutoCAD tab of the Application Link Settings in the Environment branch of the vault configuration is applied.

If this value is 1, synchronizes the entire folder that is specified as the working folder in AutoCAD Civil 3D. If this value is 0 (default), only the data shortcuts folder is synchronized.

If this value is 1 (default), the Sync Properties to File command works with AutoCAD Release 14 and older drawings but importing drawings can fail if the title blocks are synchronized also. If this value is 0, the command does not work with older drawings but importing drawings will not fail if the title blocks are synchronized.

If this value is 1, release Civil 3D data shortcuts from their workflows when they are imported to the vault by working folder synchronization. If this value is 0 (default), the shortcuts are not automatically released.
