\n\n## A Full Live-Scripted CAD Kernel and IDE in the Browser.\n\nUse code to create 3D Models with features ranging from simple primitives + CSG to complex revolves, sweeps, and fillets. Cascade Studio exposes the full power of the [OpenCascade](https://github.com/Open-Cascade-SAS/OCCT) kernel (OCCT 8.0), while providing a concise standard library for simple operations.\n\nWrite in JavaScript or OpenSCAD, visualize in real-time, and export to `.step`, `.stl`, or `.obj`. Copy the URL to share your model with anyone.\n\n## Features\n\n - **Powerful Standard Library** for primitives, booleans, sweeps, lofts, fillets, and more\n - **Sketch API** with plane parameter (`new Sketch([x,y], 'XZ')`) for drawing in XY, XZ, or YZ planes\n - **Selector API** for querying edges and faces: `Edges(shape).parallel([0,0,1]).max([0,0,1]).indices()`\n - **Measurement Functions**: `Volume()`, `SurfaceArea()`, `CenterOfMass()`\n - **Dual Editor Modes**: JavaScript and OpenSCAD\n - **IntelliSense** autocomplete with full TypeScript definitions and JSDoc\n - **Modeling History Timeline** to scrub through build steps in the 3D viewport\n - **Agent API** (`window.CascadeAPI`) for programmatic control via Playwright or developer tooling\n - **Reusable CAD Engine** — `cascade-core` npm package for embedding CAD modeling in any web app\n - Access to the full OpenCASCADE kernel via the `oc.` namespace\n - Automatic caching acceleration of standard library operations\n - `.STEP`/`.IGES`/`.STL` import and `.STEP`/`.STL`/`.OBJ` export\n - URL serialization of code for easy sharing\n - Save/Load projects to preserve code, layout, and imported files\n - Integrated GUI system (sliders, checkboxes, buttons) via Tweakpane\n - Responsive layout with mobile support\n - Installable for offline use as a Progressive Web App\n - **Free and open source under the MIT License**\n\n\n
