In a plan view, Perspectives (camera views) are created by clicking an observer point, then clicking where the observer is looking.
Visual Style settings for this perspective view: Hidden Line, Smooth Lines with Anti-Aliasing, Cast Shadows and Ambient Shadows both on, no background.
To adjust the observer, click the crop region and go to plan view. The camera will be visible and you can adjust the position. If some part of the view is invisible, make sure to adjust Far Clip settings.
