Translate your 3D CAD data between the STEP and NX formats.
SpinFire Convert is built on trusted Theorem Solutions technology which benefits from strong, long-standing business and technical relationships with Dassault Systèmes, PTC, and Siemens. These partnerships enable us to develop products and solutions specifically for users of CATIA V5, 3DEXPERIENCE, PTC, and Siemens platforms.
By leveraging Dassault Systèmes' strategic development tools (including CAA and XCAD), together with Spatial tools and APIs provided by PTC and Siemens, we ensure ongoing compatibility, high-quality data exchange, and strong business outcomes.

Are You Building Software Applications?
If you're a developer looking for SDKs to power your own engineering applications — you're in the right company, just not the right page. Tech Soft 3D’s Toolkit Division provides industry-leading development tools for 3D visualization, CAD import/export, modeling, simulation, and more.
STEP (Standard for the Exchange of Product Data) is an ISO standard file format used to represent and share 3D product data.
It is widely applied in industries such as manufacturing, engineering, and aerospace to exchange 3D models between different CAD systems. The format supports detailed information including geometry, topology, and product manufacturing data, making it useful for interoperability, reliable data exchange, and long-term archiving of product information.
Yes. STEP is defined by the ISO 10303 standard for product data representation and exchange. One of the most common implementation is the STEP-file, an ASCII text format specified in ISO 10303-21 (‘Clear Text Encoding of the Exchange Structure’). This ensures 3D objects and related CAD data can be represented consistently across different systems.
