Convert OBJ to STL C#

OBJ and STL are two common file formats used in 3D computer graphics to store and exchange 3D model data. The OBJ format is a plain text file format that contains information about the geometry of 3D objects, such as vertices, normals, texture coordinates, and faces (polygons). On the other hand, the STL format is a binary or ASCII file format that represents 3D surfaces as a collection of triangles. STL files only store the geometry of a 3D object as a mesh of triangles, without additional information like textures or colors. This simplicity makes it suitable for 3D printing, computer-aided design (CAD) applications, and rapid prototyping. In this blog post, we will show you how to convert OBJ to STL in C#.

C# OBJ to STL Converter API – Free Download

We’ll employ the Aspose.3D for .NET API to perform the conversion of an OBJ file into the STL format. This API enables the creation, modification, manipulation, and preservation of 3D formats. Moreover, it empowers C# applications to seamlessly interact with 3D documents without the need for any additional software installations on the computer.

Please download the API DLL or install it using NuGet.

Convert OBJ to STL in C#

We can convert an OBJ file to an STL format by following the steps below:

  1. Load an input OBJ file using the Scene.FromFile() method.
  2. After that, create an instance of the StlSaveOptions class.
  3. Finally, call the Save() method to save it as an STL. It takes the output STL file path and StlSaveOptions as arguments.

The following code sample shows how to convert OBJ to STL in C#.

Convert OBJ to STL With Options in C#

We can specify the STL save options while converting an OBJ file to an STL format by following the steps below:

  1. Load an input OBJ file using the Scene.FromFile() method.
  2. Create an instance of the StlSaveOptions class.
  3. After that, specify STL save options such as FlipCoordinateSystem, LookupPaths, etc.
  4. Finally, call the Save() method to save it as an STL.

The following code sample shows how to convert OBJ to STL with STL save options in C#.
