Convert X3D to STEP File

X3D to STEP ......

Provided below is a curated list of supplementary resources focusing on the interoperability and exchange between X3D and STEP files. Leverage these to streamline the X3D to STEP file conversion.

X3D File X3D

The X3D (Extensible 3D) file format is an open-source and royalty-free XML based format, developed and maintained by the Web3D Consortium. It’s designed to store two or three-dimensional models along with various visualization data, including light sources, viewport information, camera properties, special effects, and more. X3D serves as an advanced extension and a replacement for the original VRML file format, which was primarily used in web applications. Both of our X3D file converters, Autoconverter and Automesher Application, allow for the import and export of mesh entities from X3D files. For optimized file sizes, you have the option to use the binary X3DB file format instead of the default text-based X3D 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.
