CAD is a known technology and is an abbreviation of computer aided design. CAD does not draw the drawings one by one on the drafting table, but designs the information of the database by synthesizing the images of the CRT (cathode ray tube) by combining them, thereby making the work more energetic and faster. CAD is a program that allows a computer to recognize a person's design target and recognize it and design it in 2D or 3D format through arithmetic and output devices. In other words, it is a programming language that helps computers and people understand design objects at the same time. In the case of designing in the form of 2D, the user designs in the virtual drawing by using a tool, etc., and in the case of designing in the form of 3D, designs in which the object having the virtual reality is freely transformed. In the case of recently developed CAD, a three-dimensional CAD system has been developed that can display design drawings in three dimensions, and not only perfectly reproduce the three-dimensional shape on a computer screen, but also the surface area and volume strength of the three-dimensional object. It automatically calculates the physical properties and designs it in a suitable form.

In the case of CAD, it was initially based on fortran, but due to the development of object-oriented programming, it is mostly based on C language modules with their own APIs.

Three-dimensional engines are also known. Three-dimensional engines are the core software components of an interactive application (eg computer or video game machine) that require real-time three-dimensional graphics. Key features of the 3D engine include rendering 3D graphics, collision detection, sound effects, moving images, and computer networking. It is possible to create a three-dimensional image in real time, like moving a car through a three-dimensional engine, and to create a three-dimensional image in real time, like a human moving a car through an input device.
