What it does

This is a routing guide for an AI agent working on 3D work. It tells the agent how to check which 3D tools (such as Blender, FreeCAD, CloudCompare, RenderDoc, and some print slicers) are installed, and how to pick between local tools and paid cloud services for tasks like modeling, photogrammetry, rendering and preparing files for 3D printing. The file itself is mostly a catalogue and instructions; it does not perform the 3D work on its own.

Great for

  • Designers or engineers who want an agent to drive Blender or FreeCAD for modeling and rendering
  • Hobbyists preparing a model for 3D printing who want help choosing a slicer
  • Developers building game-ready assets who need a checklist of local tools

Skip it if

  • Texturing or fabrication slicing as a complete workflow: the file itself names these as structural gaps with no strong agent-native path
  • Sculpting work: the file says agent-driven sculpting is impractical beyond Blender scripts
  • Projects that must stay offline with cloud keys absent: several capabilities listed (Onshape, Fusion 360, Polycam, Luma, Octane) only work through paid online APIs

Try asking

  • “Check which 3D tools are installed on my machine before we start a modeling job”
  • “Turn these photos of an object into a 3D mesh using a free local tool”
  • “Convert my FreeCAD parametric part into a gcode file for printing”
  • “Preview a quick render of this Blender scene”

Install in 3 steps

  1. 1

    Download the skill

    The ZIP contains the 1 original files, the Apache-2.0 licence and an attribution note.

    3d-cad.zip
  2. 2

    Add it to your agent

    Claude Code (all projects)

    mkdir -p ~/.claude/skills && unzip 3d-cad.zip -d ~/.claude/skills/

    Claude Code / Agent SDK (this project only)

    mkdir -p .claude/skills && unzip 3d-cad.zip -d .claude/skills/

    Claude apps (web/desktop): Settings → Capabilities → Skills → Upload skill, and choose the ZIP.

  3. 3

    Ask for the task

    No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.

Get better results

  • Run the preflight command first so the agent knows which tools are actually available before choosing one
  • Expect the agent to ask you before using any paid cloud service; only provide an API key if you accept the metered cost
  • Keep sensitive or proprietary models on local providers, since cloud photogrammetry and rendering services upload your files
