Registry values
Value Name	Data Type	Value Data
AcadBaseConfig¹	DWORD	Controls the 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 32 — enable the Synchronize All Data Shortcuts to Vault command in the AutoCAD Civil 3D application link
AcadPnIDConfig¹	DWORD	Controls the P&ID functionality provided by the AutoCAD link. This setting requires AutoCAD P&ID or AutoCAD Plant 3D. 0 — P&ID project features only (default) 1 — P&ID project features plus asset management support
ButtonsForAll	DWORD	If set to 1, shows OK to All and Cancel to All buttons in the confirmation dialog box that appears when a user invokes the Sync Tag Hotspot command on a selection of documents and one or more of the documents has circular references. By default, the dialog box will appear once for every document in the selection that has circular references so that the user can decide what to do with each document. This setting allows the user to apply their response to all of the problem documents in the selection at one time. The default is 0, which does not show the batch response buttons.
Civil3DSyncType^1,2	DWORD	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
Civil3DSyncWorkingFolder^1,2	DWORD	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.
DisableTitleBlockUpdate	DWORD	By default, the AutoCAD link updates mapped title block attributes automatically depending on the settings configured for the vault. This value provides additional control over when title block attribute updates occur. The possible values are: 0 — perform all automatic updates (default) 1 — disable automatic updates when documents are opened 2 — disable automatic updates when documents are saved 3 — disable all automatic updates Note: To control updates to individual title blocks, see the AutoUpdate setting described in the Accruent Meridian Enterprise Configuration Guide.
DocAccessSaveThumbnail	DWORD	Controls the generation of thumbnail images during link updates. If this value is 0 (default), thumbnails are not saved. If it contains 1, thumbnails are saved. Important! If this value is 1 and thumbnail generation fails for any reason, it could prevent property synchronization, which could be more important.
DocAccessUseTmpFileOnSave	DWORD	This setting is for supporting AutoCAD drawing title block updates over a Citrix remote access connection. If this setting is 1, the drawing is opened for reading only and changing its content is performed by using a temporary file. The default is 0.
DocAccessUseTmpFolder	DWORD	This setting is for supporting AutoCAD drawing title block updates over a Citrix remote access connection. If this setting is 1 and DocAccessUseTmpFileOnSave is set to 1, the temporary file is created in the system temporary folder. If it is set to 0 (default), the file is created in the same folder as the original file.
ManualUpload	DWORD	This setting allows you to opt out of automatic uploads of AutoCAD documents. 0 — setting is disabled. 1 — automatic upload is disabled. A new Upload Document button is added to the Meridian ribbon. This button is visible in remote mode only, and is enabled after the first save of the document. 2 — ignored. 3 — automatic upload is enabled on document close only. A new Upload Document button is added to the Meridian ribbon. This button is visible in remote mode only, and is enabled after the first save of the document.
RealDwgFonts	String	The path to RealDwg fonts installed by the Meridian Enterprise setup program.
RealDwgForceValidity¹	DWORD	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.
ReleaseNewCivil3DDataShortcuts^1,2	DWORD	If this value is 1, Civil 3D data shortcuts are automatically released 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.
RepairDocState	DWORD	If this value is 1, it fixes an issue with drawings being read-only and cannot be saved when opened from PowerWeb in Online mode with a site cache configured. The default value is 0.
SyncTagsOnSave	DWORD	If this value is greater than 0, updates Meridian Asset Management Module tag references when drawings are saved.
TurnOnMenuBar	DWORD	If this value is 1, shows the AutoCAD link menu bar. If this value is 0, the menu bar is hidden.
