option: A choice associated with a command or an alternative function of a command. For example, use the LINE command to draw line objects. command: An instruction issued to the computer to complete a specific task. ![]() computer-aided design and drafting (CADD): The process of using a computer with CADD software to design and produce drawings and models. 2D drawings are the established design and drafting format and are common in all engineering and architectural industries and related disciplines. 2D Drawings 2D drawings display object length and width, width and height, or height and length in a fl at (2D) form. For example, use AutoCAD to design and document mechanical parts and assemblies, architectural buildings, civil and structural engineering projects, and electronics. representation and its equivalent tabular form is shown in Figure 13-3b.
