We've started rolling out Revit 2013 and among the new features is one called selection sets.1 There are already many different ways to aggregate objects in Revit which means it is often unclear which one to use. Regardless, I welcome the new addition - perhaps this one will work where all the others have come up short.
The topic of selection in Revit reminded me of a simple tip that, in my experience, is mostly unknown but beloved by those who do know it. The tip is that Ctrl + Left Arrow reselects the previous selection. If you have ever spent considerable effort control-selecting a large number of objects only to somehow accidentally deselected them, you can breathe a sigh of relief.
Apparently selection sets have been [in RST for some time][RSTselset] - anyone know when they first appeared? ↩
