AutoCAD's native file formats are denoted either by a .dwg, .dwt, .dws, or .dxf filename extension. .dwg and, to a lesser extent, .dxf, have become de facto, if proprietary, standards for CAD data interoperability, particularly for 2D drawing exchange. [31] The primary file format for 2D and 3D drawing files created with AutoCAD is .dwg.
DWG (from drawing) is a proprietary [3] binary file format used for storing two- and three- dimensional design data and metadata.It is the native format for several CAD packages including DraftSight, AutoCAD, ZWCAD, IntelliCAD (and its variants), Caddie and Open Design Alliance compliant applications.
3D printing, or additive manufacturing, is the construction of a three-dimensional object from a CAD model or a digital 3D model. [1] [2] [3] It can be done in a variety of processes in which material is deposited, joined or solidified under computer control, [4] with the material being added together (such as plastics, liquids or powder grains being fused), typically layer by layer.
AutoCAD is the company's flagship computer-aided design (CAD) software and, along with its 3D design software Revit, is primarily used by architects, engineers, and structural designers to design, draft, and model buildings and other structures.

The file below shows three principal views and one that shows the true lengths in the plane of the roof. (The conic dormer shows parts of an ellipse and a hyperbola .) Descriptive geometry is the branch of geometry which allows the representation of three-dimensional objects in two dimensions by using a specific set of procedures.
In contrast, although many 3D graphics file formats have been standardized (including text-based formats such as VRML and X3D), different rendering applications typically use formats tailored to their needs, and this has led to a proliferation of proprietary and open formats, with binary files being more common.
