DWG to PDF – Everything You Need to Know About It!

The DWG vector format is a basic extension that was created to support programs such as AutoCAD. It is proprietary to Autodesk, which significantly limits competition on the market. This format is improved as new versions of AutoCAD are released. Importantly, the DWG format allows you to design two-dimensional and three-dimensional drawings.

About DWG file

The name of the format is an abbreviation of the English word “Drawing”. The DWG format is a binary file format used to store 2D and 3D graphics CAD design data. DWG files contain CAD (Computer Aided Design) drawings consisting of vector data and metadata saved and compiled using binary encoding.

The DWG format is the native format of most CAD software, especially AutoCAD and its alternative applications such as IntelliCAD (ActCAD, ZwCAD, ProgeCAD, CMS IntelliCAD), gstarcad and Draftsight.

This format was developed in the 1970s by AutoDesk for AutoCAD software. DWG is a closed format and its use in the Autodesk version requires a license. It is widely available through a version developed by the Open Design Alliance and used by almost all alternative CAD software.

The DWG format has become a CAD standard and is widely used by architects, designers, constructors, engineers and surveyors for many different design purposes. DWG files are fully compatible with ActCAD software.

How to open DWG files

Open a DWG files to directly view, print, or measure data in ActCAD, or when you want to transform (copy/paste) data selectively into an Inventor sketch. The big advantage of files in the DWG format is the fact that to view the content of such a file, you can use a free DWG viewer – e.g. ActCAD. Then no program is needed.

How to open DWG files

  • Launch any ActCAD application.
  • From the menu, select File > Open.
  • Search for the DWG file you want to open.
  • Select a DWG file or files with the DWG extension.
  • You can view, edit and save the results of your work in a DWG file.
  • You can choose any other CAD file format supported by ActCAD, e.g.: DXF, DGN, DWT, DWS, DWF, STEP, STL, IGES, DSF to save the results of your work.
  • You can also save your DWG file in an older version to share it with those with older CAD applications.

Additional information about DWG files

Many open source implementation libraries are being created, but none have achieved 100% compatibility with the proprietary format. This format, in addition to the native programs that use it, is also supported in many other computer-aided design programs, and can also be displayed in online DWG viewers.



Files in DWG format can be transferred to any device and system platform, but not everywhere will be able to open them correctly.

There may be many reasons why you have problems opening DWG files. What is important, is that all common problems with files with the DWG extension can be solved by yourself. We can do it quickly and without the help of an IT expert.

DWG/DXF files are often too complex and heavy, and the number of programs used to create them is too large. And here another problem arises for us, i.e. compatibility. As already mentioned, there are a lot of CAD programs.

Each of them is specific and unique due to some feature, so it is clear that we do not have all such programs and cannot be an expert in all of them. AutoCAD from Autodesk is certainly the most widespread. It is also the most expensive. Therefore, we decided to choose the cheaper and relatively compatible program. It is normal that we are unable to determine in which program the source file was created.

Taking into account all the above-mentioned conditions, we cannot avoid modifying and dividing documents during their development in order to reach the necessary text and obtain the expected result. CAD documents cannot always be processed in the desired way.

In such cases, an alternative is to convert a DWG file to PDF format, provided that such a format is acceptable to the client. This also assumes that the client does not need to further develop and modify the file.

DWG is one of the mostly used file formats in many applications and has a hug file structure. Since DWG is a binary file format, it is not human readable like a regular PDF file format, but there are methods to convert between them without any hassle.

DWG files typically contain information about the image’s coordinates and any metadata associated with it. The format must constantly evolve to meet new needs.
