How to open a closed project?

[NetNathan]

Autocad 2011

I accidently "closed" a project and it dissappeared from my project tree. 

How do I get it back to the project tree?

Press the button in the Project Manager that says "Open project..." or, in the drop-down list in the project manager, select "Open project..."

RIGHT underneath all of the icons there is a combo box in the project manager.  It has a tiny little down arrow.  Click this box and you will see the secret list of functions, which includes an "Open Project" and "Recent..." function.

For ACADE 2012+ they decided it was time to add an "Open Project" button - imagine that! 😉
