I too am against opening files from Windows Explorer. On the other hand I am not against opening files from Sheet Set Manager (perhaps until 2008). I have been running into some issues with SDI when using SSM.
SSM seems to use the standard AutoCAD open command, which when SDI is set to 0 allows multiple drawings to be opened. Thus if you open a drawing in SSM it will allow you to open as many drawings as you wish inside of LDT.
However after doing that you cannot use File > Open (the LDT open command), even though SDI is still set to 0.
Strangely, I have had SSM opperate both the way I list it above, and one other way. I have had it set SDI to 1, which then prevents the LDT open command from working. If you set SDI to 0 once again, the LDT open command sitll wont work.
Just trying to find a common denominator here, it seems that once a standard AutoCAD open command is sent, the LDT open command becomes toast until you restart LDT.
Has anyone else run into this? Better yet - know a solution?
Thanks,
Donnie Gladfelter
