Hi Manuel, the part that has always seemed kind of strange to me about that type of arrangement just based on bounding box center is that it's very easy for the objects to collide into one another.

For example, here I did a test with Illustrator with this set of objects doing a horizontal distribute:



The result does not really seem to have much "even-ness" about it - the objects have different amounts of space between their outer boundaries and some of them even overlap over each other.

It's a kind of imprecise arrangement mechanism and that makes it a bit of an odd fit in a CAD program which tends to have more of a focus on accuracy and precision tools.
