blender will not rotate?

I tried with several objects and nothing seems to change
with this icon on or off !

if anybody knows what it does let me know !

it is a puzzle - may be a joke from the designer !

RJ2005 Take a new project blender default scene will be fine. Take the cube and move it to the side a few units. now deselect everything and add another cube. Tab to object mode select both cubes and press the “move object centers only” and then hit R for rotate. Both cubes will rotate around a center point between them. hope that helps.

I trie that with 3 objects
cube - spere - cylinder

tried to rotate with and whitout that icon on or off

don’t see any differences :confused: ?

Can you explian:)

Hope this clarifies things for anyone:

When you select multiple objects and rotate them,

with Move Object Centers button OFF, each object will revolve around the pivot point, and rotate about its own center (like the Moon always showing the same face to the Earth, or the horses on a carousel).

with the button ON, the object centers revolve around the pivot point, but each object does not rotate about its own center. Each object moves but maintains its original orientation with respect to the rest of the world (like the benches in a standard Ferris wheel ride).

Each object moves but maintains its original orientation with respect to the rest of the world (like the benches in a standard Ferris wheel ride).

Haha… but can you say that in French?

I had put a cube - sphere - cylinder

i could not see the difference with the spere in the middle - pure luck

The small video made me see the meaning of it

now i begin to understand - i’ll play with this feature to better understand it

i never saw anything in the book about this !

Tanks

Not easy to describe in words

Here is my summary

When you select more than one object in object mode
Blender calculate a new center of gravity for all the objects

and this affect the behavior of scale and rotate

reset - Icon - “move center only”

Scale --> scale all the objects and the distances between objects
Rotate --> Rotate all the objects around their own center and around the center of gravity of all the objects

Set Icon

Scale --> Scale only the distance between objects
Rotate --> Rotate all the objects around the center of gravity of all the objects

What do you think:confused:

Unless it affect other things too :confused: :eek:
