When you work in paper space on a Layout tab, you can still view your drawing in model space. First you need to create a layout viewport in paper space; this allows you to view your model space entities from paper space.
Within a layout viewport you can modify the model space entities, but it is often more convenient to modify these entities on the Model tab.
Zooming or panning the drawing in model space or paper space affects the entire drawing, unless you use multiple windows or viewports.
The first time you switch to a Layout tab, your drawing seems to disappear. This is normal. You must create at least one layout viewport to see your work.
NOTE You can switch between model space and paper space using the Model/Paper toggle in the status bar, or by typing mspace or pspace.
