Most drawings consist of two-dimensional (2D) views of objects that are three dimensional (3D). Though this method of drafting is widely used in the architectural and engineering communities, it is limited: the drawings are 2D representations of 3D objects and must be visually interpreted. Moreover, because the views are created independently, there are more possibilities for error and ambiguity. As a result, you may want to create true 3D models instead of 2D representations. You can use the AutoCAD drawing tools to create detailed, realistic 3D objects and manipulate them in various ways.
