3D Viewport
A viewport is a display window within the workspace that is used to show a 3D representation of the model or product being edited. Only one viewport can be active at a time.
The representation of the model or product is determined, in each viewport, by a viewpoint (the position of the observer) and by a look-at point (the point being observed). Several types of representation exist, depending on the active interface module. These render types are accessible via a right-click on the name of the viewport type in order to display the viewport's context menu.
