The DWG is a file format that is primarily assigned to files that are created using the AutoCAD "Computer Aided Design" application program. AutoCAD basically is a CAD based development program that was originally developed by the AutoDesk Corporation.
The DWG file format can also be assigned to files that are created with a range of other CAD programs like the IntelliCAD software. File with the DWG extension also comprise of a database of 2D as well as 3D drawings that have been created using the CAD application. These files are useful in storing the meta data and design that describes the contents of the particular file.
In addition to the problem described above, i.e. the lack of the appropriate application to support the .DWG file, there may be several reasons that cause problems with opening and operation of the data format:
A quite common problem is the lack of application in the appropriate version. Even if you have an application, with the help of which you should open the .DWG file, you may have a problem with it because of its version. Perhaps in previous versions the application has not yet supported the .DWG file, so download the update and check again.
If you have already installed the appropriate application, and it is the correct version, the file may not open correctly, because the operating system does not have information that this program supports the file. So you need to "show" which program the computer should use. To do this:
It also happens that the file you want to open is corrupt and therefore there is no such possibility. In this situation, you should find its different version, or ask a person from whom you got, to send it again.
There may be several reasons why you cannot open the file with .DWG extension. Directly on this website you can find a solution of the most common problem with the .DWG file – that you do not have on your computer the appropriate program to open the file.
