 If you've ever tried to load, edit or create a complex STEP assembly in a web browser, you know how tricky it can be. STEP is the standard format engineers use to share CAD models, but browsers don't understand it natively. You usually need desktop software or a server to convert it.
 
-With **Bitbybit v1.0.0-rc.1**, that changes. You can now load STEP assemblies directly in the browser, explore their structure, extract individual parts, and export to web-friendly formats. Everything runs locally using Bitbybit OCCT WebAssembly.
