3DS to STEP: Resources

Find below a compilation of resources that delve into the interoperability and exchange of 3DS and STEP files. These will prove beneficial in the process of converting from 3DS to STEP files.

3DS File 3DS

The 3DS (3D Studio) is a widely recognized format used for storing polygonal mesh models. It supports additional features such as model names, reusable geometry component instances, materials with transparent colors, and texture images. However, due to legacy constraints, 3DS model names are limited to 8 characters, and a single 3DS mesh object can only contain up to 32,767 triangles. As a result, when exporting to the 3DS file format, larger meshes must be divided into smaller shells. Our Autoconverter and Automesher Application 3DS file converters simplify this process, allowing you to effortlessly convert any 3D model into the 3DS format. This makes it easy to import your model into DIALux lighting software, which also supports 3DS file extension.


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.
