The file type .DWG refers to AutoCAD Drawing Database file types. These file store all the data created by the AutoCad software in a database format. Mostly these database files contain digital data of the 2D and 3D images rendered in the AutoCAD software. There have been incremental improvements in the file format over the years from AutoCAD.
The file format is designed in such a way that it offers inter-format operability and hence can also be used on some of the other platforms of Autodesk software. The file is also supported by its open source ASCII version .DXF
Files with DWG extension are used by databases that store projects created with CAD (Computer Aided Design) programs, typically AutoCAD, but many other tools also use this format. DWG files store 2D/3D drawing project data and content metadata. DWG is a binary format, however a text format counterpart, called DXF, also exists.
Compared to other simlar formats, DWG offers high precision and quality of drawings, features very important in many CAD environments. DWG format is used by many professionals, such as engineers, architects, and designers.
DWG file are compatible with many CAD tools, but because various different types of DWG format were developed (DWG 2000, 2004, 2007, 2010, and 2013) and although similar in many aspects, they slightly differ in structure. Thus, not all CAD tools support all those formats equally.
DWG file structure: header, class definitions, template (optional), padding, image data, object data, object map, object free space, second header.
If you cannot open the DWG file on your computer - there may be several reasons. The first and most important reason (the most common) is the lack of a suitable software that supports DWG among those that are installed on your device.
A very simple way to solve this problem is to find and download the appropriate application. The first part of the task has already been done – the software supporting the DWG file can be found in the table. Now just download and install the appropriate application.
The inability to open and operate the DWG file does not necessarily mean that you do not have an appropriate software installed on your computer. There may be other problems that also block our ability to operate the AutoCAD Drawing Format file. Below is a list of possible problems.
If you are sure that all of these reasons do not exist in your case (or have already been eliminated), the DWG file should operate with your programs without any problem. If the problem with the DWG file has not been solved, it may be due to the fact that in this case there is also another rare problem with the DWG file. In this case, the only you can do is to ask for assistance of a professional staff.

If you want to associate a file with a new program (e.g. my-file.DWG) you have two ways to do it. The first and the easiest one is to right-click on the selected DWG file. From the drop-down menu select "Choose default program", then click "Browse" and find the desired program. The whole operation must be confirmed by clicking OK. The second and more difficult to do is associate the DWG file extension to the corresponding software in the Windows Registry.
Many files contain only simple text data. It is possible that while opening unknown files (e.g. DWG) with a simple text editor like Windows Notepad will allow us to see some of the data encoded in the file. This method allows you to preview the contents of many files, but probably not in such a structure as a program dedicated to support them.
