The OBJ ( OBJ) file extension is used for an ASCII-based file format for 3D geometric models that was developed by Wavefront Technologies. It is one of the oldest and most commonly used 3D file formats today and has been adopted by various digital content creation, visualization, and animation software programs.
The OBJ file format stores 3D object data in a plain text format, making it both simple to create and edit and relatively lightweight compared to other 3D file formats. The OBJ files are built around a group of lines that start with letters between "v" and "g" followed by numbers or strings. This structure is one of the reasons OBJ files are so common.
Features
OBJ files can contain 3D models of surfaces, curves, lines, regions, and points. Each one of these objects contains different elements that are necessary to describe its shape, such as a mesh information and surface normals points. Additionally, they carry geometry data in the form of points that define each vertex of the object, including indices to reference the points in the polygonal and linear structures found inside the model.
Similar File Extensions
Other 3D object file extensions similar to OBJ include 3DS, PLY, STL, DAE, FBX, etc.

After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .OBJ) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .OBJ extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .OBJ file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .OBJ extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .OBJ extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .OBJ file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .OBJ file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .OBJ file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .OBJ file) will be extended to the maximum.
It is also good to check
- if the .OBJ file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
