The abbreviation CAD stands for Computer Aided Design. CAD includes tasks related to the design, construction, planning and improvement/modification of products, which are carried out with the help of a computer and special software. Geometric models are created/modified, calculations made, or simulation created. Everything from development to handover and manufacturing are important parts of the construction process.One can distinguish between simple 2D drawings and complex 3D models.

We encounter CAD or CAD systems in many branches of technology. They are mainly used by architects, engineers, draftsmen and/or designers. Due to the use of CAD systems, construction drawings or construction plans are rarely created by hand these days.
