no I don’t have kids!
each object numbered 1 to 9 is parented to the previous one.
3 is parented to 2 etc.
so if I move 1 then all the rest should follow.
I positioned them all in a row close to each other.
then blender says Hey! they look better apart!
well I don’t agree. what is happening?
thanks. ctrp P to parent.
Do you have unapplied rotations or scales on any of the meshes - no.
don’t remember how but the problem is solved.
thanks all
