I have created a document to client specs of 1080 x 500 px. Now he wants a version of just 540px wide. Is there a way to scale the whole hype doc with all the interactivity and assets intact?
If you add all your elements to a group, you can scale that group while holding command to scale everything down while selecting that group and clicking and dragging on a corner. Make sure none of your layers are locked!
I'll give that a try...
