1. A method comprising: aligning a three-dimensional (3-D) model with a view of a physical environment captured by a camera; generating an augmented reality view by superposing elements of the 3-D model and the view of the physical environment, at least some of the elements of the 3-D model being initially hidden behind the view of the physical environment within the augmented reality view; configuring an exclusion list for elements of the 3-D model; imposing a virtual window that penetrates a wall of a structure within the augmented reality view, the virtual window clipping the view of the physical environment and elements of the 3-D model that are not on the exclusion list that intersect the virtual window, while preserving any elements of the 3-D model that are on the exclusion list that intersect the virtual window, to produce a display that shows initially-hidden excluded elements of the 3-D model located within the virtual window in the context of initially-hidden elements of the 3-D model located beyond the virtual window, in the larger context of the view of the physical environment; and displaying the augmented reality view with the virtual window on a display device.
