Yet Another CAD Viewer

A CAD viewer capable of displaying OCP models (CadQuery/Build123d/...) in a web browser.

Features

• Cross-platform: works on any modern web browser.
• All GLTF 2.0 features (textures, PBR materials, animations...).
• All model-viewer features (smooth controls, augmented reality...).
• Load multiple models at once, load external models and even images as quads.
• Control clipping planes, transparency, edge/vertex sizes and explode each model.
• View and interact with topological entities: faces, edges, vertices and locations.
• Select any entity and measure bounding box size and distances.
• Hot reloading while editing the CAD model (using the yacv-server package).
• Fully-featured static deployment: just upload the viewer and models to your server.
• Build123d playground! Code and build your model fully inside the browser: demo.

Usage

The example is a fully working project that shows how to use the viewer.

You can play with the latest demo here (or without animation).

Related projects

• cq-studio provides an alternative workflow that detects file changes instead of relying on an interactive environment like Jupyter for hot-reloading. Uses the same backend and frontend behind the scenes.
• build123d-docker provides docker images for Yet Another CAD Viewer and other projects, with automatic updates.
• OCP.wasm ports OCP (OpenCASCADE for Python) and supporting libraries to WebAssembly, enabling full in-browser CAD model generation and manipulation. This powers the build123d playground provided by this viewer.
