Document Summary
A visual depiction of a concept or model that captures the essential features or characteristics of the system from an engineering perspective while generally not trying to depict realistically the actual visual look of the system. For example, a vehicle may be shown simply as a moving mass: a rectangle labeled m in a diagram. Diagrams are used in problem solving to help engineers think through a problem. They are also used in documents and presentations to communicate ideas to others. A process in which a software package is used to create a detailed two- or three- dimensional representation of a physical structure. In a modern cad program, each physical part in a full assembly is represented by a detailed description of its mass, volume, and composition in a virtual 3d space. A 3d cad model serves the role of a virtual prototype and can be easily modi ed.
