## What it is
Cascade Studio is a browser-based, live-scripted CAD IDE built on the OpenCascade (OCCT) kernel compiled to WebAssembly. It lets users write JavaScript or OpenSCAD code to create 3D models with real-time visualization and export to STEP, STL, or OBJ formats.

## Use cases
- create 3D CAD models by writing code in the browser
- convert OpenSCAD scripts to STEP/STL/OBJ files
- model parts with fillets, sweeps, lofts, and boolean operations without installing CAD software
- embed a parametric CAD kernel in a web application via the cascade-core npm package
- share parametric 3D models via URL
- programmatically drive CAD modeling with an agent API for automation

## When to choose
- you want script-driven parametric CAD with no local installation
- you need OpenCASCADE BREP precision (fillets, sweeps, STEP import/export) in a browser
- you want to embed a CAD engine in a web app
- you prefer JavaScript or OpenSCAD syntax over GUI CAD tools

## When to avoid
- you need a traditional GUI-based CAD workflow with mouse-driven modeling
- you require offline desktop performance for very large assemblies
- you need drawing/2D documentation output or CAM features
