The viewports display a selected part of the model on the print layout.
Viewports are placed on plot layout. On a plot layout, you can create several viewports. Each layout viewport displays a view of the design space e.g. floor plan, section, elevation, 3D views with a scale and orientation that you specify.
The viewports can be edited either on the original view or on the print design sheet.
You can crop, scale and change orientation either on plot layout or the original design space.
