Primitive Commands of CADD

CAD is an old concept
It must be noted that the term CAD is an old concept, born when the first computer drawing systems appeared and people switched from the drawing table to the computer.
A Computer Drafting technician works with designers and engineers to convert their ideas and concepts for new products and designs into accurate drawings that specify size, shape, materials and specifications. These drawings are then used by professionals in manufacturing, consulting, and construction to produce the desired product or structure. Designs are created using computer aided drafting (CAD) equipment.
It seems like every year advancements in computer technology go farther and quicker than the year before it. When I first started using CAD software all the lines had to be put in manually with commands on the keyboard. They would tell the software to create the lines starting point, length, and what angle to direction it. This process seemed to take forever compared to the way lines are created nowadays. With the CAD software available today you can perform all kinds of commands in a 3D environment. For instance, if you wanted to add a radius to a corner that has already been created, all you have to do is click the command for a fillet. It will then ask you for a dimension on the radius, and after you enter the dimension it will create a perfectly smooth and rounded corner.
