Duplicating Room Conditions/Dimensions

[152431]

Hey There-

 

I thought I remember hearing about/seeing a video tutorial once about a feature that allows me to quickly mirror a ceiling height onto another room in a structure?

I suppose creating the structure height before I start cutting up the interior is the easiest solution in the future.  But I am getting into as built scenarios where the existing structure has several different ceiling heights on the basement floor, and then a consistent height on other floors.

 

Thanks

Whala.  Thanks so much.  VERY helpful as you imagine ; )
