Convert STEP to OBJ File

STEP to OBJ ......

Find below an assortment of resources that delve into the interoperability and exchange of STEP and OBJ files. These will prove beneficial in the process of converting from STEP to OBJ file.


The STEP (STandardized Exchange of Product) file format is extensively used for the exchange of 3D data across various computer systems, including CAD, CAM, and CAE. As STEP geometry data is stored in a text-based format, exporting triangular meshes with thousands or even millions of faces using Autoconverter software may lead to larger file sizes. However, if your geometry defines a manifold solid, our software will strive to create an optimized faceted BREP representation, potentially reducing the STEP file size by up to one-third. It’s crucial to note that while the STEP file format supports colors per assembly, it lacks an alpha component. Consequently, any transparency settings will not be retained in the final STEP file.


The OBJ (Alias Wavefront Object) is a text-based file format that is widely used for 3D geometry objects across various 3D software programs. The OBJ file format can store named group objects, surface materials with transparent colors and texture images, and geometry primitives in the form of quads or triangles. However, it’s important to note that during the OBJ file conversion using our Autoconverter software, any quad primitives will be simplified into two triangles, as only triangular facets are supported. Additionally, due to its textual format, OBJ files tend to have larger sizes compared to binary file formats like 3DS (3D Studio) or SKP (SketchUp).
