Cascade Studio — The Complete Guide: Solid Modelling in JavaScript Code Right in the Browser
Cascade Studio is a browser-based CAD environment where the model is code. You write a few lines of JavaScript, or OpenSCAD-style syntax, and the solid is built instantly in the 3D view. Under the hood runs the OpenCascade kernel, so the result is true solid geometry rather than a triangle mesh. There is no registration and no install, and the site can be installed as an app for offline work.

Parametric solid modelling in the browser through JavaScript code on the OpenCascade kernel, with STEP, STL and OBJ export.
Get it from the vendorWhat you get
- Solids and operations — primitives, boolean operations, sweeps, lofts and fillets.
- Sketches and selection — 2D sketches and face and edge selection in code.
- Measurements — volume, surface area and centre of mass of the solid.
- Import and export — import STEP, IGES and STL, export to STEP, STL and OBJ.
- Share by link — the model is stored in the URL itself and sent to a colleague in one click.
Who it suits
Mechanical engineers and programmers who want a parametric part they can reproduce, change by editing one number and keep under version control. There is no graphical sketching interface and every step is written as code, so anyone who prefers to work with the mouse will feel limited. It is a single-developer project under the MIT licence, completely free including for commercial use.

A quick, install-free way to try code CAD with a real B-Rep kernel and STEP export. Excellent for parametric parts, less suited to anyone looking for a graphical interface.
