Probably one of the most exciting sub-tools of the express tools is the change space under the layout tools. This tool, allows you to transfer any objects from model space to paper space or vice-versa.

For instance, there was one time that I want to put all drawing legends in my drawings in paper space. But the problem is in paper space I have to re-draw again all the necessary legends that I needed when in facts all legends are already drawn inside the model space. All I need is just to transfer it or copy it from model space to paper space.
