Difference between 'Bounding Box center' and 'median point' pivot? In the options from pivot point, is the option 'Bounding Box center' the same as the option 'median point'?
for the second question :


the bounding box center is not the same as median center :

-The Median center is calculated as the average of all selected points ( vertices or object centers ) so it depends on the density distribution of the mesh 

-The bounding box : is the smallest box (Cube ) that can contain the mesh of an object while aligned to the local space 

-The bounding Box center will always be at the center of this bounding box regardless of the density distribution of the mesh inside
