For individual components with simple geometries 2D CAD will allow drawings to be made faster, but the output will only be just a set of 2D drawings. These are not ideal for representing a complex product, especially when communicating with your design team, customers, salespeople, buyers, and suppliers, because they are subject to misinterpretation and error, which in turn can become costly and time consuming for a company. 3D is the way we naturally visualize objects in our world, therefore combining more than one view of a 2D technical drawing is not common practice for everyone.
