WHAT IS AUTOCAD EXACTLY?

AutoCAD is a computer-aided design (CAD) application that allows users to produce complex 2D and 3D drawings of real-world objects and abstract concepts. Since its beginnings, it has created everything from houses to spaceships, cars, and roller coasters. It uses a tree-like hierarchical data structure to allow users to design particular pieces or entire systems using various modeling tools for structures, components, and networks. It can handle large amounts of data because of its file-based design, which incorporates 3D transformations, texturing, and lighting, among other geometric operations.
