CAD INTRODUCTION 

CAD stands for Computer-Aided Design, and it is a technology used to create, modify, and optimize designs using specialized Software on a computer. CAD is used in a wide range of industries, including architecture, engineering, construction, and manufacturing, to create detailed and accurate digital models of physical objects and structures.

CAD software can be used to create 2D drawings or plans, as well as 3D models that can be viewed from any angle. The software typically includes a variety of tools for creating, editing, and manipulating geometric shapes and lines, as well as text and dimensions. It also usually includes features for rendering and visualizing designs, and for creating animations and virtual tours.

CAD is widely used because it allows designers to create and modify designs quickly and easily, and to share and collaborate on designs with others. It also allows for more accurate and efficient design processes, as well as the ability to simulate and test designs before they are built.

Overall, CAD has revolutionized the way designs are created and shared, making the design process more efficient, accurate and cost-effective.
