So what is the difference between default, local, and shared when you deploy AutoCAD / AutoCAD Architecture? Both default and local stores onto your local workstation; the difference is that you get to pick where you want it to go (local) and keeping content data like AEC styles and DesignCenter Content in the ProgramData folder (default).
The Shared Mode is where things get a little more interesting, and for larger firms, this is the preferred method since standardization across all workstations is vital for productivity. I mean, you don’t want teams in the same firm using completely different Templates and Layer Standards. Some points to consider:
Thankfully uninstalling the software from one workstation does not remove the content from the shared location. Imagine the headaches that would’ve happened if that was the case! Craziness!
