I am now going through the individual scenes and adding dimensions and annotations, but they are showing up in all the scenes, when i just want to have them shown in the scene i added them in?
You can obviously go through the other scenes and hide what you dont want to see, but that seems long winded
Create layers for dimensions per scene.
Say scene1 shows layer_dim1 and all dimensions created only for scene1 have this specific layer assigned to them. And scene1 has this layer visible.
Carry on doing the same thing for scene2: its dimensions have layer_dim2 assigned to them and is only visible in scene2
etc.
Hide isn’t the best way to achieve what you are after.
