    Use Cases & Benefits

    • Provides a browser-based 3D CAD application enabling online model design, editing, and rendering without local installation.
    • Delivers near-native performance by compiling OpenCascade to WebAssembly and integrating with Three.js for powerful in-browser 3D modeling.
    • Use for creating and editing complex 3D CAD models directly in the browser with advanced geometric operations and snapping tools.
    • Use for managing hierarchical assemblies and exporting/importing industry-standard CAD formats like STEP and IGES in a web environment.
    • Use for developing multilingual CAD applications with a customizable office-style interface and dynamic workplane support.

    From the README

    A browser-based 3D CAD application for online model design and editing.

    Chili3D is an open-source, browser-based 3D CAD (Computer-Aided Design) application built with TypeScript. It achieves near-native performance by compiling OpenCascade (OCCT) to WebAssembly and integrating with Three.js, enabling powerful online modeling, editing, and rendering—all without the need for local installation.
