Write parametric 3D models in JavaScript or OpenSCAD. 10-20x faster evaluation with guaranteed manifold output.
JavaScript evaluation is 10-20x faster than OpenSCAD parsing. Instant feedback for rapid prototyping.
Full TypeScript support with autocomplete. Catch errors at development time, not runtime.
98-99% OpenSCAD language compatibility. Migrate existing projects with minimal changes.
Chainable methods with the Shape class. Write readable, maintainable code.
Install as npm package. Works in browser and Node.js. Build CAD tools into your apps.
Built on manifold-3d engine. No topology errors, clean boolean operations every time.
// Parametric Bolt Class
class Bolt {
constructor(length, diameter) {
this.length = length;
this.diameter = diameter;
}
build() {
return Shape.cylinder(this.length, this.diameter / 2)
.union(Shape.sphere(this.diameter * 0.9)
.translate([0, 0, this.length]))
.color('silver');
}
}
export default new Bolt(20, 6).build();module bolt(length=20, diameter=6) {
cylinder(h=length, r=diameter/2);
translate([0, 0, length])
sphere(r=diameter * 0.9, $fn=6);
}
bolt();JavaScript gives you classes, async/await, npm packages, and modern tooling.
OpenSCAD provides familiarity for existing CAD users.
Design functional parts with parametric models. Export directly to STL for slicing.
Create precise mechanical assemblies. Test fits and clearances before manufacturing.
Rapid iteration with instant preview. Share models as JavaScript modules.
Join developers who are building the next generation of parametric design tools.
