Switch between open documents in Revit 2015

[tdaniel]

Is there a way to switch between opened projects?  I've used OpenandActivateDocument to open a project and now I need to switch back to the previous.  

Thanks!

Yes you can. Openandactivate also works for already opened documents, so all you need to do is to make some sort of list of documents, which you can use to activate the desired document.
