What Does an .OBJ File Offer and How Do You Use It?

Different 3D designers can export and import .OBJ files, which are common 3D format. OBJ files were first developed by the Wavefront Technologies in 1992. It is known as a useful file format since it is straightforward to use and supports a number of software programs, allowing file sharing between various applications to be made simple.

What are the Essential Features of the OBJ Files?

 .OBJ file comes with several important characteristics. These consist of the following:

By splitting an object’s surface into tiny, triangular “tiles,” it allows users to be able to represent objects with complicated or irregular shapes. Since each tile may be changed independently of the others during the tessellation process, it is simpler to control and render this design.

The ability to express 3D object geometry and surface features like texture mapping as well as shading is a crucial component of the OBJ files. This .OBJ file format is strong for producing realistic renderings for complicated three-dimensional situations thanks to its adaptability.

Information about free-form patches is also included in OBJ files. These patches give designers the ability to create seamless, smooth surfaces devoid of seams or distortions, making them perfect for producing very realistic textures like fabric or skin.

When compared to related file formats such as STL files, OBJ ensures high-resolution data.

Unlike the STL files, that only accept one color for every object, they may store textures as well as numerous colors within a single object.

Using OBJ to Open and Convert to Other File Formats

Various methods exist for opening an OBJ as well as converting them into different formats. Use 3DS Max, Cinema 4D, Solidworks, or Blender software, which makes it simple to import different 3D models inside the OBJ format. This then transforms and exports them in any format you require.

For instance, you must first start the program and select File > Import before you can import the designs into Blender. The option to upload designs in various formats will then appear. You can import the OBJ file by choosing the Wavefront (.obj) file format.

You may also easily and quickly convert the .OBJ file to formats such as STL, WRL, GLB, PLY, as well as many others by using online programs like 3DViewerOnline and 3D Slash. There are a lot of possibilities accessible, this is why there are always tools available to ensure you get the very best from .obj files.

To change the OBJ file to another format, you must choose the desired format of the output from the interface of the software. Depending on the tool you will be employing, this procedure can be simple. For instance, if you are using a professional-grade product such as Blender, you may select the appropriate file type from the list of common formats by going to File, then Export.

Repairing OBJ Files

You can use MeshLab and MeshMixer, which are two excellent apps, to fix the OBJ file. You first must import the OBJ file into the program by choosing File > Import before you can correct or edit when using MeshMixer.

Using the tools on the left-hand side of the toolbar, you may start making changes to the File after it has been loaded, depending on whatever way you would love to edit as well as repair the file. For instance, you can make use of sculpting tool in reshaping some areas in the model.

Additionally, you should choose one of its left-side toolbars, like the Primitive or Edit toolbar. To further edit this model, you can make use of features like mesh smoothing and hole filling.

To hone and polish your design, you could also experiment with additional useful tools such as Booleans and Mirroring. If the model needs 3D printing support, you may add them via selecting Analysis, where you’ll find several support options under the Overhangs category.

Finally, make sure that you save and also export your final OBJ file such that you may utilize it in some other applications after you’re done making all necessary adjustments. Select Export as well as the format of the file you want in order to save the design to accomplish this.

Benefits and Drawbacks of the .OBJ Files


Like any file type, .OBJ files come with their own advantages and disadvantages.


Because OBJ files enable many textures and colors, you may swiftly transfer intricate designs and patterns with various colors. Also, you can import and export the .obj files to 3DS, STL, and DXF, among other well-known formats.

These files can be imported into well-known CAD software applications for more modification and editing.

So far the design guidelines for your additive manufacturing are followed, .OBJ files are ideal for a variety of 3D printing purposes, from prints of small-scale to huge industrial parts.


.OBJ files can be used in 3D printing, but you will only be able to print those that are specifically designed to ensure 3D printing.

Similar to other files, it can be difficult to open as well as view, most especially when the appropriate software has not been installed. Loading and rendering could be slow, most especially when they are detailed or complex.

Why You Should Choose the .OBJ File?

When deciding between OBJ as well as other file types for the 3D modeling, no specific solution answers it all. Either format can be a suitable option for you, depending on the objectives and goals. This description of the .OBJ file that we provided you will help in your decision as to whether or not you should use this file for your upcoming project.

Also, it is appropriate for tasks requiring minute, detailed details, including creating architectural models as well as incredibly lifelike digital items.

However, if you are working on simpler, smaller designs, there might be better options than OBJ. For those tasks, a simpler format like 3DS or STL would be more appropriate. After going through this article, you should know if this suits your needs.
