What is the .DWG File Extension?

.DWG File Extension Description:

The DWG file extension contains different drawings created and used with the Autodesk AutoCAD application. It is accurate to say that a .dwg file is a database of objects used in a CAD application. DWG is the acronym for "drawing".

The .dwg format belongs to the Vector Image Format, which is a database file used to store 2D and 3D images from CAD applications. Vector images, or sometimes termed as geometric modeling, is the use of points, curves, and lines, along with shapes and other polygons to create an image. These objects are all based on mathematical equations that represent every image common in Computer Aided Design (CAD) graphics.

Originally, vector graphics is mainly used in the context of 2D computer graphics, and convert it into raster display using the application's GUI. Other modes found on a .dwg format include texts, multimedia (video), and 3D rendering.

The images with the .dwg file extension are rasterized graphics composed of images in an array called pixels. These pixels contain colors using the RGB (Red, Green, and Blue) format, where each pixel contains values from 0 to 255. These values will change the basic colors in different shades, as used with the image.

In order to manipulate a .dwg image format, drawing software is necessary to create and edit vector graphics. Editing each object using mathematical formulas can modify the image. These formulas are used to twist, bend, stretch, and color each of the components accordingly.

Considering that DWG files are somewhat bulky depending on the number of objects contained in the project, loading it using CAD applications to view it might take some time. Many programmers developed viewing applications, such as DWG TrueView, to open these files without resorting to loading the original application for DWG.
