Concepts: Design Versus Drafting

I feel it very important that I make a point here: Drawing with graphic primitives creates a picture, and drawing with objects creates a model. Drawing with graphic primitives is called drafting, and drawing with objects is called designing.

Here, I'm going to admit a bias—I was trained as an architect and tend to lean toward architectural examples and illustrations to drive a point home. Consider the example of a construction project, commercial or residential (it doesn't matter). When the architect draws up a set of drawings and prints them on blue-line paper, he creates what he refers to as construction documents. The building contractor who receives a set of these documents (drawings) takes many things for granted. He or she assumes that the drawings were put together by a person well versed in the procedures, methodologies, materials, and systems that go into the creation of a building. The documents that the contractor looks at are truly nothing more than blue lines, arcs, circles, and text on white paper. Because both the architect and contractor are educated in the process of building construction—because they both can speak the symbolic language shown on the drawings—they both assume that the circle with the big plus through it represents a ceiling light fixture. For the same reason, they both assume that the large S with the lines through it represents a light switch.
