The Create Similar tool has become my new favorite Button. I use it about . . . . . a 1000 times a day.
I call it the 'Gimmy One of These" button.
This button shows up on the ribbon after you select an item. The bonus is it also adapts to the properties of the item selected.
For example if you select a wall it will adapt the properties of the new wall to be created to include wall type, base and top constraints as well as offsets.
This also works with Structural objects and MEP objects.
Very nice in deed !
