Convert STL to OBJ via C#
Instantly convert STL to OBJ without needing AutoCAD® or any other rendering software.
Aspose.CAD for .NET
Overview
How to Convert STL to OBJ Using C#
In order to convert STL to OBJ, we’ll use Aspose.CAD for .NET API which is a feature-rich, powerful and easy to use document manipulation and conversion API for C# platform. Open NuGet package manager, search for Aspose.CAD and install. You may also use the following command from the Package Manager Console.
Package Manager Console Command
PM> Install-Package Aspose.CAD
Steps to Convert STL to OBJ via C#
.NET programmers can easily load & convert STL files to OBJ in just a few lines of code.
- Load STL file with Image.Load method
- Set an object of CadRasterizationOptions with page height & width
- Create an instance of ObjOptions class and set its VectorRasterizationOptions property
- Call Image.Save method while passing the resultant file path & object of ObjOptions
System Requirements
Before running the .NET conversion code, make sure that you have the following prerequisites.
- Microsoft Windows or a compatible OS with .NET Framework, .NET Core.
- Development environment like Microsoft Visual Studio.
- Aspose.CAD for .NET DLL referenced in your project.

STL What is STL File Format?
STL, abbreviation for stereolithrography, is an interchangeable file format that represents 3-dimensional surface geometry. The file format finds its usage in several fields such as rapid prototyping, 3D printing and computer-aided manufacturing. It represents a surface as a series of small triangles, known as facets, where each facet is described by a perpendicular direction and three points representing the vertices of the triangle. Resultant data is used by applications to determine the cross section of the 3D shape to be built by the fabber. There is no information available in the STL file format for representation of colour, texture or other common CAD model attributes.

OBJ files are used by Wavefront’s Advanced Visualizer application to define and store the geometric objects. Backward and forward transmission of geometric data is made possible through OBJ files. Both polygonal geometry like points, lines, texture vertices, faces and free-form geometry (curves and surfaces) are supported by OBJ format. This format does not support animation or information related to light and position of scenes. An OBJ file is usually an end product of the 3D modeling process generated by a CAD (Computer Aided Design). The default order to store vertices is counter-clockwise avoiding explicit declaration of face normals. Though OBJ files declare scale information in a comment line yet no units have been declared for OBJ coordinates.
