Enable the Master Drawing Mode
Please note that if this option is checked, it disables the Solidworks option Performaces→No preview during open (faster).
[PDF] Master Drawing File Extension
PDF
TIF
Always preview/open released/frozen Master Drawing if it exists
if checked, MechworksPDM always previews/opens the Master Drawing file where available and if the state is RELEASED or FROZEN, instead of the Native CAD drawing.
Always Preview checked-in Master Drawing if it exists
if checked, MechworksPDM previews always the created Master Drawing file if it exists and if the state is CHECKED_IN, instead of the Native CAD Drawing.
When this option is checked, MechworksPDM calls the OnApproveMasterDrawing.LST script with the parameter @MASTER_DRAWING_IS_CREATING set to "1".
After checking this parameter, the script can decide whether to draw or not the revision table in the newly created .PDF/.TIFF.
Always Open checked-in Master Drawing if it exists
if checked, MechworksPDM always opens the created Master Drawing file if it exists and if the state is CHECKED_IN, instead of the Native CAD Drawing.
Always create Master Drawing on a new revision
When checked, the Master Drawing is created (by invoking the script OnCreateMasterDrawing.LST) at every New Revision or Increment Revision State operation.
Delete file from script
When checked, the deletion of the Master Drawing file is demanded to the OnCreateMasterDrawing.LST script.
In this way, the script can handle Master Drawing files manually created by the user, for example for file formats not supported out-of-the-box by MechWorks PDM.
Basically, to leverage the Master Drawing Mode also on files extensions not supported by DBWorks (for which no direct save-as or MDConvert is available), the user can place the .PDF/.TIFF file in the correct directory location, manage the deletion/update of the files withing the OnCreateMasterDrawing.LST ( for example using the DBWShell FileDelete) and having MechWorks PDM to display the Master Drawing also for such not-supported file formats.
Native CAD Drawing File Extensions
a list containing the extensions of the files to be managed, assuming they can have a Master Drawing created for them.
Assign only files path root
When checked, it is sufficient to assign a root folder, under which all the Master Drawing files will be created/searched for.
The rules for creating the folder structure.
Example
Suppose the MDM path list contains the following entries:
Z:\archive1\s1\
Z:\archive1\s2\
Z:\archive2\s1\
When creating the MDM for the file M:\archive1\s1\P1.SLDDRW, the .PDF file is created in the directory Z:\archive1\s1.
When creating the MDM for the file M:\archive3\s4\P2.SLDPRT, the .PDF file is created in the same directory of the document (M:\archive3\s4) as it hasn't been found in the path list a directory with the same name.
Master Drawing File Locations
A set of directories where to search for the Master Drawings; it first looks in the same directory of the Native CAD Drawing, then in sequence, in all the directories declared in this option. The logic is very similar to that of the Revision Files, so that the Master Drawings is created directly in the locations assigned by this list.
In case the option 
Assign only files path root is enabled, only the first location will be considered as root.
