One of the more annoying issues users have with the AutoCAD Sheet Set Manager is trying to delete the .dst file its associated with.  Sometimes it is necessary to erase a sheet set and start over, or maybe part it out into separate sets and it is necessary to eliminate the .dst file due to the rule AutoCAD has about layouts only being associated with a single sheet set.

The first thing you must do is make sure that absolutely no one on the network has that .dst file open or loaded on their “recent” list of sheet set projects in the SSM.  Once you have confirmed this, go to the drop-down menu of the SSM and right-click the project associated with the .dst file you are attempting to delete (this can also be done from the sheet list if you already have the project open within the SSM). After right-clicking, select “Close Sheet Set” from the short cut menu.  Now you can go to the .dst file on your PC or server and delete it without it “magically” returning to haunt you.

If you, or anyone on the server is referencing a .dst file, it cannot be deleted. It is not necessary to remove the sheets from the sheet set, only that everyone be out of it and have it removed from their lists within the SSM drop-down menu.  Once the .dst file is erased, you are free to re-associate the layouts to any existing or new sheet set.
