This little tip comes from Emmanuel Di Diacomo, one of our Customer Success Engineers. It is often useful to be able to display views on your screen in Revit in a specific order when you tile the views. Instead of manually having to move each of your views into the correct location, you can first use the Title option to correctly place windows and then use the technique below to change the order.
The principal is basically very simple, just click on each of the view windows in the order that you would like them to appear in the end.
Make sure that you click on the Title bar of the view in order to make sure you get it. To make sure the views appear correctly, click on the "Tile" option once again. This will reorder the views in the order you selected.
Autodesk Revit Products uses the counterclockwise sense to display your windows and let them turn around the virtual center of your screen. If the 1st clicked windows does not appear as the 1st window in your ordering, just click back again on each window like you were pushing pieces of a puzzle around. Each window will push the other one in the order.
This may be an old tip, but it seemed like a good one.
