Here I am posting a composite elevation of a portion of the stone barn at Morven Park in Leesburg, VA.
Composite Elevation with two of the three images faded to 50% opacity
The “elevation” is actually a composite of three images, each rectified to respect the scale of 1:96 (or a quarter inch equals a foot) when printed at 300dpi. The individual images are posted below.

Maria Mitchell Hybrid Drawing
Above is what I like to call a “hybrid drawing” of the historic Maria Mitchell House located on the island of Nantucket. A hybrid drawing is one of two things, or possible both: It is a photographic image that behaves like a measured drawing (it is scalable and can provide quantifiable data), or it is a measured drawing that is rich in the way a photographic image is (materials, colors, actual as-found existing conditions are depicted photographically).
Line drawing with key to individual rectified images
Above is a view of the line drawing with all of the rectified images that compose the hybrid drawing “frozen”. In other words, in the CAD drawing, these layers of information are turned off and made invisible so as to see just the line-work itself and a series of polygons that correspond to bit map/raster images that are referenced by the drawing.
Below are a series of images showing each individual rectified photographs as it is situated in the context of the drawing. These added together make the composite image at the top of this post.
