DWG File Extension  What is .Dwg and how to open them? ▷ 2020

After programming, digital drawing is possibly the one with the most formats like video. There are many types of files that contain graphic elements. The best known are JPG and PNG, but the world is much bigger than these.

Among the many computer files of digital drawing, the DraWinG or .DWG is one of the most important, especially for AutoCAD users those who love 2D and 3D design.

In this article we are going to teach you everything you need to know about what .DWG files are and are used for, as well as its significance and importance as far as digital drawing is concerned.

What is .DWG files and what are they used for?

.DWG file extension

The DWG is a computer file which is used to store graphic information of a digital design. It stores vector information, which will allow you to increase or reduce its dimensions without affecting the quality of the image, as happens with other files of this type. Further, Unlike others, it can store 3D vector information.

This last characteristic has made the format the one chosen by Autodesk for most files exported from your AutoCAD, the world’s most widely used 3-dimensional digital design software. However, this was not the direct creator of the format.

To know the origins of DWG you have to go to the beginning of the 80’s, when the developers of IBM released one of the many versions of the operating system MS-DOS. It contained this new type of file for your basic drawing software, which instead of exporting in PNG or JPGE, I did it in DWG.

The utility of DWG and its convenience to be used as the default format for 2 and 3 dimensional digital design made Autodesk choose it as the icing on the cake AutoCAD, whose first edition would be released in 1986.

However, not everything is perfect with the DWG, since with each release of a new version of the AutoCAD a new DWG was created and it was not always compatible with the old one. In other words, version 1 was not compatible with version 2 or 3. This led to the creation of another format that would allow data to be shared between different versions of DraWinG called DXF or Drawing eXchange File.

How to open and view .DWG files on smartphones or computers?

Opening a DWG file and viewing what’s inside is an extremely simple process that won’t take more than a few minutes to do. Yes, to streamline everything you will need to have AutoCAD from Autodesk, since this program will allow you to open the format with just a couple of clicks on it.

On Windows PC

The AutoCAD program has native support for vector files of the DWG, so if you have this installed, you can view all the elements in this format you want.

What you have to do in this case is simply right click on the file in question and then follow the path “Open with”> “AutoCAD”.

After that, the software will open and you will see what is inside the element, as well as you can edit it and make the changes you want with the tools of the program.

On Mac computers

On computers MacOS the process is basically the same. You simply must have the AutoCAD program installed and when you make a couple of clicks on the file you want to see, it will run and you can view the content or edit it according to what you want.

On Android mobile phones

To view files DWG on Android you will need to download and install the mobile version of AutoCAD what Autodesk has developed for you.

While this is much less powerful than desktop, the most important thing is that with it you can see files DWG without any problem.

What you should do is simply enter the app, touch on “Open” and find the file you want to view. After that you can make changes with the tools that this app puts at your disposal..

On iPhone devices with iOS

On devices Manzana it is also possible to install the version Mobile of the AutoCAD to do this task. Once everything is ready, you just have to start it and touch “Open” to view or edit the content within the vector drawing file.

List of the best alternative applications and programs to open a document with a .Dwg extension without using AutoCad

While AutoCAD is the default software for editing and viewing this image format type, it is not the only option you have. Here is a list of programs and applications alternatives to the Autodesk program to view and edit DWG documents seamlessly.



This is one of the most powerful competitors that AutoCAD has on the market and it is no wonder. It has tools that are just as good for engineering and architecture professionals. As you can expect from 2D and 3D drawing creation and editing software, it can perfectly read any DWG file thanks to its DXF support. However, it is paid, so you will have to pay a license to use it.



A program used even by professionals in the cinematographic industry to create the structural base of cities made entirely with special effects. Do you remember those wonderful worlds from Guardians of the Galaxy or realistic changes like those in The Origin? Well, things like that can be done with this software that has a unique level of detail. In this you can open any DWG file thanks to the native support it has integrated for documents of this format.



A fairly cheap alternative that will allow you to create all kinds of 3D wonders, although with more limited tools than the previous two. However, for the task of opening DWG files it works perfectly, so it will come in handy for it.
