Propagate Extents

A very underutilised tool in Revit is the Propagate Extents tool for Levels and Grids (Datum Lines).

When you set up a views Levels and Grids just the way you would like, and would like this to reflect in other views, just select the Datum Lines (Levels or Grids) and then select the Propagate Extents tool in the Ribbon and then tick the views you would like to replicate the Level or Grid extents to.

The Datum extents will then be replicated into the views selected.

Another way of controlling Datum Extents is using Scope Boxes and then applying it to a view. Propagating Extents is a nice method without having Scope Boxes setup in your project.
