About

• An open-source project that compiles OpenCascade to WebAssembly and integrates it with Three.js to provide near-native 3D CAD modeling, editing, and rendering in the browser
• Supports a wide range of CAD modeling features, including creation of 3D shapes such as boxes, cylinders, and solids of revolution, 2D sketching, Boolean operations, extrude/loft/sweep, and offset
• Provides precise design and editing aids such as object/workplane snapping, axis tracking, automatic keypoint detection, and visual tracking guides
• Built-in advanced editing such as chamfer/fillet/trim/split and move/rotate/mirror, length/area/volume measurement, document management, and import/export of industry-standard formats (STEP, IGES, BREP)
• Provides a practical user experience with an Office-style UI, hierarchical assembly management, a multilingual (i18n, Chinese/English) interface, and 3D viewport/camera control
