The process of engineering begins with an idea. The ability to communicate many technical ideas requires a translation from thoughts into pictures. A quick way to share an idea is through a technical sketch. Technical sketching is a tool used by engineers and inventors. If the idea turns out to be a good one, these first sketches are turned into detailed CAD drawings or solid models, which include measurements and other critical details. The initial sketches can be used to develop the first prototypes. The freehand sketch is the first step taken to turn an idea into reality.
