OCCT Assembly | Bitbybit

📄️ Introduction

Understand what OCCT assemblies are, why STEP files matter for CAD workflows, and preview your first assembly model in the browser.

Convert STEP files to web-optimized GLTF/GLB format directly in the browser with privacy-preserving local processing.

Extract and navigate assembly hierarchy from STEP files - find part labels, retrieve shapes, and apply custom styling to individual components.

Export OCCT shapes to STEP files with preserved colors using the assembly document structure for CAD software compatibility.

Create structured CAD assemblies with parts, instances, and hierarchies. Export STEP files compatible with FreeCAD, Fusion 360, and SolidWorks.
