2D CAD systems offer two-dimensional drawing capabilities with precise control over the scale, dimensions, and placement of the objects and geometrical figures on the canvas. Once considered a cutting-edge software package, today, 2D CAD systems are considered lower-end software systems. But there are two most important types of CAD software – those capable of 2D designs only and those capable of 3D designs. One can classify CAD programs using many different criteria. A computer system is used in a CAD program to assist the CAD engineer in putting his concepts into designs using a wide range of tools.
It is a class of software packages architects, designers, and engineers use to create 2D and 3D designs and models of physical components, machines, and objects.ĬAD design software has replaced manual drafters' conventional design tools and revolutionized manufacturing, engineering, architecture, and product design. Many CAD programs or CAD design software are available as free, open-source installations and commercial software packages. Computer-Aided Design, or CAD, is not a new concept but has taken the world of engineering, construction, and manufacturing to the next level. When you look around at any manufactured product or modern construction marvels, you are looking at one of the finest examples of CAD design.
