copy objects from one scene to another

Question

I opened a blend, and I created 2 scenes. in the 1st I have a box and in the 2nd. I have a door. save my file and then use the command duplicate window of the information bar in the window tab. in each window place a scene, as you can see in one is the door and in another is the box.

My question is the following and consists of three parts!

How can you copy objects from one scene to another? Can you simply pass an object from one scene to another as you usually do when you move an object from one layer to another layer? Is there any way to do this?

Answer 1

The the Make Links operator to link objects between scenes.

Select a bunch of objects, press Ctrl + L Make Links > To Scene then pick a scene from the list.

Beware that without further action these linked objects remain linked and are in fact one and the same, that means any transformations made in one scene will propagate to others both in Object Mode and in Edit Mode.

To make them independent select them and press U Make Single User then choose an option. Object will make them move independently but still share Object Data or geometry. Object & Data will make them unique and completely independent.

For 2.8 series this can be found under the 3D View header menu, either under Object > Relations > Make Single User, or Object > Make Links.

API methods

Code to link the context object of context scene "Scene" to another scene named "Scene.001"

import bpy
C = bpy.context
D = bpy.data

in 2.8

>>> C.scene
bpy.data.scenes['Scene']
>> D.scenes['Scene.001'].collection.objects.link(C.object)

2.5x to 2.7x

>>> C.scene
bpy.data.scenes['Scene']
>> D.scenes['Scene.001'].objects.link(C.object)
