cli-anything-freecad

Complete CLI harness for **FreeCAD** — 258 commands across 17 groups covering ALL workbenches.

Prerequisites

FreeCAD must be installed: `freecadcmd` must be in PATH.

Installation

pip install -e freecad/agent-harness

Basic Usage

cli-anything-freecad --json <command>           # JSON output for agents
cli-anything-freecad --json -p proj.json <cmd>  # With project file
cli-anything-freecad                            # Interactive REPL

Preview, Live Preview, and Motion

FreeCAD is currently the deepest preview integration in this branch.

Preview commands:

# List preview recipes
cli-anything-freecad --json -p proj.json preview recipes

# Capture a real 4-view bundle
cli-anything-freecad --json -p proj.json preview capture --recipe quick

# Start poll-mode live preview
cli-anything-freecad --json -p proj.json preview live start --recipe quick --mode poll --source-poll-ms 500

# Query current live state without rendering
cli-anything-freecad --json -p proj.json preview live status --recipe quick

# Stop live preview publication
cli-anything-freecad --json -p proj.json preview live stop --recipe quick

Typical `quick` bundle artifacts:

• `hero.png`
• `front.png`
• `top.png`
• `right.png`

Live preview persists:

• `session.json`
• immutable bundle directories
• `trajectory.json`

`preview live status --json` is intended for agents and includes a compact `trajectory_summary` in addition to `_session_dir`, current bundle refs, and `_trajectory_path`.

Viewer commands:

cli-hub previews inspect /path/to/bundle-or-session
cli-hub previews html /path/to/bundle-or-session -o page.html
cli-hub previews watch /path/to/session --open
cli-hub previews open /path/to/bundle-or-session

Motion commands remain separate from preview and are used for final truthful frame rendering and showcase videos:

cli-anything-freecad --json -p proj.json motion new --name spin --duration 6 --fps 24
cli-anything-freecad --json -p proj.json motion keyframe spin --time 0.0 --part 0 --position 0,0,0
cli-anything-freecad --json -p proj.json motion render-video spin output.mp4
