Open OBJ file, and how to open it

If you are into graphic designing and are searching for what is an OBJ file and how to open obj file, then this article is for you.

So, without any further ado, let’s start the discussion.

What is an OBJ file?

OBJ file is one of the main file designs in 3D printing and illustrations applications. It is the most picked document design for multicolor 3D printing and is typically utilized as a nonpartisan trade record design for trading non-energized 3D models in illustrations applications.

An OBJ file is an exemplary 3D picture document design that is traded and opened by different 3D picture-altering programs.

These files comprise a three-dimensional article that incorporates the 3D directions, surface guides, polygonal appearances, and other item data.

These documents may likewise save references to at least one. The OBJ file design is viewed as a Universal 3D model configuration, as 3D picture altering applications for the most part support it.

  11. Select the .OBJ record and snap Open. The .OBJ record is right now open on your Mac.

Instructions to change over OBJ file into STL

Transforming OBJ document Into STL with the Spin 3D Mesh Converter Software. What’s more, to do this transformation, you ought to follow these means:

  • Firstly Download Spin 3D Mesh Converter Software on your PC:-

Begin downloading the Spin 3D Mesh Converter and afterward by adhering to the straightforward directions shown on the screen dispatch/introduce the Program.

  • Then you import the OBJ documents into the Program:-

Tap the Add File button situated in the primary toolbar to open the document locater window. Discover your information from that point and select the OBJ record that you wish to change over.

  • The subsequent stage will be of choosing the envelope for yield:-

Pick the objective from your PC where you would wish to store the changed record over to follow going through the transformation interaction.

  • Then set your yield design:-

After choosing the objective of your yield. Tap on the drop-down bolt on the left-hand side of the Program close to the “Yield Format” starting from the drop menu of record designs, select the STL document configuration, and presently whatever transformation you will straightforwardly change over into STL design that you have picked.

  • At last, begin changing throughout OBJ document to STL file:-

Ultimately, click the “Convert” button situated in the base right-hand corner of the Program, and this will then, at that point, start your course of changing over the file.


With people moving on to digital media platforms, designing 3D graphics has become one of the crucial parts of this virtual world, because who doesn’t want to maintain that engagement ratio?

And hence, a designer should be well versed with different file formats like OBJ which is versatile and supports most of the 3D editing software, thus helping in gaining that perfect output every time.

Frequently Asked Questions:

Who created the OBJ file format?

The OBJ file format was created by Wavefront Technologies. It is a company that deals in computer graphics software that was founded in the late 1980s in Santa Barbara, California.

What is the purpose of the OBJ file format?

The main purpose of the OBJ file format is to enable the transfer of 3D models between different software programs.

This file format stores geometrical data like; vertices, texture coordinates, normals, vertices and other attributes that define the shape of the 3D object.

Can an OBJ file contain texture?

Yes, an OBJ file can contain textures information such as references to texture image files and texture coordinates, which allows the 3D models to be textured and coloured using images applied to their surfaces.

Additionally, the texture information can be stored in the same OBJ file in the form of geometry data, or it can be stored as a separate material library file regarding the OBJ file.

Can OBJ files contain animations?

OBJ files are a 3D geometry file format that can contain 3D models with vertex and polygonal data. However, this file format does not support animation on its own as they contain the static geometry of the 3D model.

And therefore, you may need to use a different file format that supports animation data, like; the AutoDesk FBX or COLLADA (DAE) formats.

How is geometry data stored in OBJ files?

The geometry data in OBJ files are stored in a series of text lines that define the faces, vertices, and texture coordinates of the 3D object.

Moreover, this file format is designed to be simple and human-readable, which makes it a popular choice for saving 3D models that can be used with various software.

How is material information stored in OBJ files?

The material information in OBJ files is stored in a separate file with the “.mtl” extension. It also contains information about the materials that are used in 3D objects, including their name, texture map, color and other properties.

How is texture information stored in OBJ files?

The texture information in OBJ files is stored in separate image files and then referenced in the material file using the “map_Kd” command. Plus the texture file can be in any image format, such as BMP, JPG, and PNG.

What is an MTL file and how is it related to OBJ files?

An MTL file is a separate file that is used with OBJ files simultaneously in order to define textures and materials for 3D objects.

It has the same file name as that of an OBJ file but with a different file extension, i.e., (.mtl). Moreover, it carries information such as texture maps, colors, names and other properties.

Can OBJ files contain multiple objects?

Yes, OBJ files can contain multiple objects and each object can have its own set of vertices, normals, texture coordinates, and faces, as well as its own material properties.

Can OBJ files contain multiple material definitions?

Yes, OBJ files can contain multiple material definitions, typically stored in separate MTL files. Now, each material definition has a unique name that contains properties such as material color, specular color, texture maps, shininess, and transparency.

Not to mention, there is no limit to material definitions, and hence each material can be referenced by one or more objects or groups of faces.

How are vertices defined in OBJ files?

The vertices in OBJ files are defined by the “v” command, followed by the x, y and z coordinates of the vertex.

How are normals defined in OBJ files?

The normals in an OBJ file are defined by the “vn” command, followed by the x, y and z components of the normal vector. By defining the normal vectors, you can control the lighting and shading of the 3D model, thus making them more realistic and three-dimensional.

How are texture coordinates defined in OBJ files?

The texture color in OBJ files is defined with the “vt” command, followed by “u” and “v” coordinates of the texture coordinate.

Can OBJ files contain vertex colors?

Yes, the OBJ files can contain vertex colors. These colors are defined by the “vc” command, followed by the red, green and blue color components of the vertex color.

Can OBJ files contain face groups?

Yes, OBJ files can contain face groups that are also known as smoothing groups or face smoothing groups. The face group is specified using the “s” command followed by a numerical value that represents the smoothing group.

What is the maximum number of faces that can be defined in an OBJ file?

Generally, there is no specific limit on the number of faces that can be defined in an OBJ file, because it is primarily limited by the amount of available system memory.

However, it is worth noting that it can be difficult to work with a high number of faces as it can take its own sweet time to load and manipulate in 3D modelling software.

What are some common issues encountered when working with OBJ files?

Some common issues that a user can encounter while working with OBJ files are as follows;

  • Missing files.
  • Inconsistent vertex winding.
  • Large file size.
  • Non-standard extensions.
  • Normal issues.
  • Redundant vertices.
  • Missing or incorrect material definitions.
  • Non-manifold geometry.
