SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Converts short natural-language prompts into complete engineering-grade 3D model specifications, enabling deterministic assemblies, manufacturing details, and ready-to-use geometry for CAD/BIM/visualization workflows.

Core Features & Use Cases

  • End-to-end CAD generation: from prompt to fully structured assembly with hierarchy, constraints, and manufacturing data.
  • Multi-domain applicability: furniture, electronics, machinery, vehicles, and buildings with realistic dimensions and materials.
  • Renderable geometry: outputs a detailed geometry array suitable for real-time visualization and export to GLB/STL/OBJ/PLY.

Quick Start

Describe an object, for example "design a bookshelf", and the system will produce a complete engineering CAD spec with renderable geometry.

FAQPage Schema
How do I generate a 3D CAD model from a text prompt?

To generate a 3D CAD model from a text prompt, describe an object like a bookshelf. The system outputs a structured CadSpec JSON with parametric dimensions, materials, and a renderable geometry array for CAD and BIM workflows.

Can I export procedural geometry to STL or GLB formats?

Yes, you can export procedural geometry to STL or GLB formats. The system produces a detailed renderable geometry array suitable for real-time visualization and direct export to GLB, STL, OBJ, and PLY files.

Does this tool support BIM workflows for building assemblies?

Yes, this tool supports BIM workflows for building assemblies. It generates complete engineering-grade 3D model specifications with hierarchy, constraints, and manufacturing data that can be consumed by CAD and BIM tools.

What is the best way to create engineering assemblies with manufacturing details?

The best way to create engineering assemblies with manufacturing details is using natural-language prompts. The system produces deterministic assemblies with parametric dimensions and materials for furniture, electronics, vehicles, and machinery.

Do I need CAD software to use the generated 3D-modeling specifications?

You do not need CAD software to generate the 3D-modeling specifications, but you need CAD, BIM, or visualization tools to consume the structured CadSpec JSON and renderable geometry array outputs.

Why use a procedural approach for generating CAD models?

Use a procedural approach for generating CAD models to achieve deterministic assemblies from short prompts. This ensures realistic parametric dimensions, accurate manufacturing details, and ready-to-use geometry for visualization.
