Computer-aided design (CAD) is the use of computer technology for the process of design and design-documentation. CAD is relied upon in various fields such as engineering, manufacturing and survey. Many CAD programs have an in-built means of programming their functionality. Examples being a macro language or lisp. Other programs may offer, or have had reverse-engineered, an API for more in-depth coding. There are various drawing formats, with .dxf being a ubiquitous one for interchange.
