SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires build123d.

What problem does it solve?

Turning text requests into editable 3D geometry is slow and requires CAD expertise, but this Skill converts your description into build123d parametric code and renders the result in a browser for fast iteration.

Core Features & Use Cases

  • Text-to-3D via build123d: Create solids from plain prompts (e.g., gears, brackets, phone cases) by generating and executing Python CAD code.
  • Reference-image modeling: Use an image path plus optional description to guide geometry reconstruction, including researching likely real dimensions.
  • Browser CAD viewer workflow: Immediately view models, toggle render modes, inspect cross-sections, and export STEP for CAD/slicing tools.
  • Viewer-driven region edits (✎): Select an area in the 3D viewer, submit an edit request, and have Claude apply it by updating the corresponding model script.

Quick Start

Use the command /render a gear with 12 teeth to generate the model, run the CAD code, and open the rendered result in the viewer.

Frequently Asked Questions about render

FAQPage Schema
How do I generate 3D CAD models from text descriptions?

You can generate 3D CAD models from text by converting descriptions into build123d parametric Python code, which executes to export GLB and STEP artifacts for immediate browser viewing and iteration.

Can I export STEP files for CAD and slicing tools?

Yes, you can export STEP files for CAD and slicing tools. The skill executes build123d Python scripts to generate geometry and supports STEP export directly from the browser viewer workflow.

How do I edit a specific region of a 3D model in the browser viewer?

To edit a specific region of a 3D model in the browser viewer, select the target area using the edit tool, submit your modification request, and the system applies it deterministically by updating the underlying build123d script.

Does build123d support creating 3D models from reference images?

Yes, build123d supports reference-image modeling by using an image path plus optional description to guide geometry reconstruction, including researching likely real dimensions to build the parametric CAD code.

What is the best way to iterate on 3D modeling designs quickly?

The best way to iterate on 3D modeling designs quickly is using a browser CAD viewer workflow that auto-loads rendered GLB artifacts, allowing you to toggle render modes, inspect cross-sections, and apply queued viewer edits.

Do I need Python to use this 3D modeling workflow?

Yes, you need Python to use this 3D modeling workflow because the skill generates and executes build123d parametric Python CAD scripts to create solids and export geometry artifacts for the viewer.
