Layout viewports are objects that display views of model space. You create, scale, and place them in paper space on a layout.
On each layout, you can create one or more layout viewports. Each layout viewport is like a closed circuit TV monitor of a view of the model at a scale and orientation that you specify.
When you use the MVIEW command to create a new layout viewport, you specify the view that you want to display in it with one of several methods:
After you create a layout viewport, you can change its size and properties, and also scale and move it as needed.
To prevent accidental panning and zooming, each layout viewport has a Display Locked property that can be turned on or off. You can access this property from the Properties palette, the right-click menu when a layout viewport is selected, a button on the Layout Viewports tab on the ribbon, and a button on the status bar when one or more layout viewports are selected.
