2D drafting and drawing is the process of creating and editing technical drawings, as well as annotating designs. 2D Drafting is the creation of accurate representations of objects for manufacturing and engineering needs. It is used to fully and clearly define requirements for concepts or products so as to convey all the required information that will allow a manufacturer to produce that component.
Computer-aided drafting can be done in two (2D) or three dimensions (3D). While more and more companies are using 3D drafting, 2D Drafting continues to remain popular.
2D drafting systems are a big improvement over traditional hand drafting, doing away with all the complications of scale and placement on the drawing sheet. One extension of 2D drafting is 3D wire frame. Each line has to be manually inserted into the drawing. The final product has no mass properties associated with it and cannot have features directly added to it, such as holes.
CAD software for 2D drafting can be used to draft designs more quickly and with greater precision, without using stencils and technical drawing instruments. 2D CAD software also allows users to document and annotate drawings with text, dimensions, leaders, and tables.
