How does the AI 3D model generator work?

Open the code editor, then type a description in the AI bar like 'create a gear with 20 teeth and a 5mm bore hole'. AI generates complete JSCAD JavaScript code with parametric sliders. The code streams into the editor in real time, then auto-runs to render your 3D model. You can follow up with modifications like 'add 4 mounting holes' or 'make it taller'.

JSCAD is an open-source JavaScript library for creating parametric 2D and 3D models using code. It uses Constructive Solid Geometry (CSG) to combine primitives like cubes, spheres, and cylinders with boolean operations (union, subtract, intersect). Models export to STL for 3D printing.

Can I export models for 3D printing?

Yes. Export to STL (most common for 3D printers), OBJ, AMF, 3MF, and DXF (for CNC and laser cutting). All exports happen in your browser — no server upload, no account needed.

Do I need to know JavaScript to use this?

No. Use the AI to generate code by describing what you want in plain English. AI writes the complete JSCAD script with parameter sliders. You can then tweak dimensions using sliders without touching the code. For advanced designs, knowing basic JavaScript helps.

Can AI fix errors in my JSCAD code?

Yes. When your code has an error, the AI bar auto-suggests 'Fix this error'. Hit Enter and AI reads your code plus the error message, then generates a corrected version. It streams the fix into the editor and auto-runs it.

Yes, completely free with no signup. Powered by JSCAD, an MIT-licensed open-source project. AI generation, 3D rendering, and file export all run in your browser.

What 3D shapes can I create?

Any shape that can be built from primitives and boolean operations: gears, enclosures, phone stands, brackets, vases, mechanical parts, architectural models, and more. JSCAD supports cube, sphere, cylinder, torus, polygon extrusions, hulls, and polyhedra. Combine them with union, subtract, and intersect.
