What is a .DWG file

The DWG file extension identifies drawing files created in AutoCAD from Autodesk. “DWG” is actually a short form for “DRAWING”.

The DWG files store 3D and 2D computer aided design drawing data including metadata. They also contain geometric information like vector image data which are written out in binary codes.

In addition, DWG is the main local format used by many CAD apps and packages such as Interlaced, PowerCAD, AutoCAD and its variants. As a matter of fact, DWG files formats was developed by AutoDesk the founders of AutoCAD back in the ’80s together with the first Autocad version.

These files don’t have native support in many  software applications.

The DWG format first made its appearance to the world with the launch of the AutoCAD drafting software as a native file format for the design application.

It is the preferred format of professionals in the design environment, such as; interior designers, engineers, and architects. This is because it is a perfect file format for design-oriented projects.


It must be added that the files with the dwg format consists of all the data that users input when making a CAD drawing. Such data include photos, maps, designs, and geometric data.

When it comes to compatibility with other design-based software, then the DWG extension is highly recommended.

How to Open DWG Files with and without Autocad

If you intend to just view and maybe print a file with the dwg extension, having to purchase an expensive AutoCAD license may seem a bit too much.

Files with DWG suffix can be opened directly on AutoDesk products like AutoCAD 360 and A360 Viewer.  However, they may also be opened without the need for AutoCAD. You can actually open them using other software applications, such as; CorelDRAW and Microsoft Visio.

The best option you have is to get a DWG viewer.

Here is how you can open a dwg file without AutoCAD using randomly chosen software applications, such as; Microsoft Visio and CorelDRAW.

You can view it without Autocad. You have to get a free viewer like A360 or use an online viewer.

How to Create a DWG using an AutoCAD app


If you own an AutoCAD design-oriented software application like the Home Designer Pro, Home Designer Suite, or Home Designer Architectural app, you can export 2D line-based files.

To do this simply:

  1. go to “File”
  2. then “Export” where you can select either the “Export Current View” option, or the “Export All Floors” option.

The AutoCAD version you would like the 2D line-based file to be exported to can also be specified. But please note that you could face compatibility challenges depending on the software being used.


If you then want to create either a .dxf or .dwg file on your Home Designer app you will have to follow these steps.

  1. First of all, you will need to launch the Home Designer app.
  2. Next, open that .plan file you would like to export.
  3. Thirdly, go to the drop-down menu then click on “File”, “Export” and finally on “Current View” to display either DXF or DWG.
  4. You can also click “File”, “Export” and then “Export All Floors” in either DXF or DWG as well.


Important Notes:

 Note that if you are using the Home Designer 2019 or the previous version app, the file format you would only be able to export in is DXF.

So, if you are using this app while you are in the “Export Drawing dialog” box, select an AutoCAD app version that is compatible before you choose the “Export” option.

Whenever you intend sending a drawing file to another person using an AutoCAD app version that is older, try to know what AutoCAD version the other person is using.

Once you have found out the AutoCAD version the person has installed on their device, you need to then select that exact version (on the drop-down menu) before you export the drawing file.

About .DWG file extension

The DWG file extension was first developed as a native format for the CAD package Interact. The author was Mike Riddle. It was later on licensed by Autodesk to be the foundation of AutoCAD.
Today, this format is the most widely used for drawing. You can open it in many CAD software.
The files with the .dwg are in a proprietary format for images composed of design data. The DWG is associated with the DXF file extension which stores files in the ASCII version.
AutoCAD is a computer-aided design and drafting program. It is the industry standard when it comes to 2D and 3D design work.
Autodesk defines designs and iterates that this format is the native format for their computer-aided design applications.
However, in the year of 1996, Autodesk disclaimed exclusive used of the this format. You can open these files in Windows using the free program DWG Tru View.
