Change origin of collections I am trying to animate a fbx imported file originally made in solidworks, since it was made in solidworks all the parts are in different layers. In order to change the rotation pivot I need to change the origin however nothing happends when I try going the object/set origin route.

Is there a way to change the origin of collections or merge a collection to a single object so I can change the origin?

There are serveral hundreds of subcollections so I cannot select them individually.
The only way I think you can solve that is by pressing alt-p to clear parent and keep transformation then set the origin to geometry, after that you are free to delete the useless empty and start animating.
