They all rely on one file format that every system understands—STEP. STEP files have become the backbone of modern engineering collaboration, making it possible to exchange data seamlessly between different CAD systems, manufacturers, and engineering teams worldwide. Yet many engineers use STEP files daily without really understanding how they work or how to get the most out of them. ...
