AUTOCAD
This workshop based on drafting and detailing, Cad software for mechanical and civil design uses either vector based graphics to depict the objects of traditional drafting, or may also produce raster graphics showing the overall appearance of designed objects. However, it involves more than just shapes. As in the manual drafting of technical and engineering drawings, the outputs of CAD must convey information, such as material, processes, dimensions and tolerances according to application specific conventions.
Computer-aided drafting is widely used in the civil engineering field because of its ability to plan sites a lot easier than hand drawings, it can help design a lot of engineering supplies, and is constantly upgrading.
It is almost used to civil engineering field for design and detailing and it is the best for structural drawings. It is useful to solve design issues resulting in inaccurate designs.
