One thing that will please many users, especially those that come from a pure AutoCAD background is the introduction of Snap Overrides; Hey! But remember Revit isn’t AutoCAD :-). You have always been able to access the snaps from keyboard shortcuts, however, when you are now working in a view or whilst moving, copying, rotating, or arraying existing elements, you can access the snap overrides from the right-click contextual menu.
You will also find a new snap type called “close”. Why “close” you may ask? The new close snap allows you to close a valid open loop of elements whilst you are sketching, if you have more than one option to close the loop, just use the Tab key to snap through the different options.
Start by sketching an open loop of walls. 
When you want to close the loop of wall, just right mouse click to invoke the Osnap override command. 
Finally, choose “close” from the Osnap overrides list. This will complete the loop of walls. Remember, if you have more than one option to close the loop, just use the Tab key to cycle through the different options, until you find the one you require.
