# Phase 0 — Containerize the CLI
> **Status: ✅ DONE (2026-06-17).** `step-parser:dev` builds for linux/amd64 and all
> three sample assemblies (MR16/MR27/MR28) pass the full pipeline — load, BOM .xlsx,
> 6-view OSMesa thumbnails, geometry query, and dimensional-diagram SVG. Validated on
> a Mac (arm64) via QEMU emulation; image arch confirmed x86_64. Deps frozen in
> `requirements.lock.txt`. Two fixes were required (see **Fixes applied** below).
**Goal:** prove the heavy native stack runs on **linux/amd64** (the Unraid target) before any web code is written. This is the highest-risk part of the [step-parser](projects/active/step-parser.md) roadmap; everything after it is conventional React-on-FastAPI.
What's being de-risked:
| Path | Library | Container concern |
|------|---------|-------------------|
| STEP load + geometry | build123d → cadquery-ocp (OpenCASCADE) | manylinux x86_64 wheels; OCC needs GL/X11/OpenMP runtime libs |
| 6-view thumbnails | trimesh + pyrender | **offscreen GL with no GPU** → forced onto OSMesa software rasterizer |
| Dimensional diagram | cairosvg | cairo / pango / gdk-pixbuf system libs |
| BOM | pandas + openpyxl | none |
| Translation | anthropic (Claude API) | network + `ANTHROPIC_API_KEY` (skipped in this phase) |
## Files (all in repo root, `skill.src/` untouched)
- `Dockerfile` — `python:3.11-slim-bookworm`, amd64-pinned, OSMesa + cairo system libs
- `requirements.txt` — Python deps (floor pins; freeze to a lockfile after first green build)
- `.dockerignore` — keeps `.step` samples, drops caches and pre-generated outputs
- `.env.example` — `ANTHROPIC_API_KEY` (translation only)
- `build.sh` — buildx build for linux/amd64 (+ registry push hints)
- `smoke-test.sh` — runs MR16/MR27/MR28 through BOM + query + diagram; checks artifacts
## Run it (on a Docker host)
> Docker is **not** installed on the dev Mac this was authored on, and it's arm64.
> The build runs anywhere with Docker + buildx: Unraid itself, or a Mac/PC with
> Docker Desktop. From arm64 the amd64 build uses QEMU emulation (slow first time;
> the OpenCASCADE wheel is large).
```bash
./build.sh # → step-parser:dev (linux/amd64)
./smoke-test.sh # → _phase0_out/ with xlsx, pngs, svg per sample
```
Ad-hoc single file:
```bash
docker run --rm -v "$PWD/_phase0_out:/data" step-parser:dev "/data/MyPart.step" --no-translate
```
## Pass criteria
For each of the three samples the smoke test must produce, with a clean exit:
- `*_bom.xlsx` (kernel loaded + assembly traversed + Excel written)
- at least one `*_<view>.png` (pyrender succeeded under OSMesa — the riskiest item)
- `*__external-diagram.svg` (cairosvg succeeded)
All three green ⇒ Phase 0 done. Freeze the lockfile and move to Phase 1 (FastAPI wrapper).
## Fixes applied during Phase 0
1. **PyOpenGL / OSMesa version clash (packaging).** `pyrender 0.1.45` hard-pins
`PyOpenGL==3.1.0`, but the OSMesa offscreen backend needs `OSMesaCreateContextAttribs`
(added in PyOpenGL ≥3.1.5). The Dockerfile installs pyrender's pin, then force-upgrades
with `pip install --no-deps --upgrade "PyOpenGL==3.1.7"` (leaves pyrender untouched,
avoids the resolver conflict). Without this, all 6 renders fail with an ImportError.
2. **`external_diagram.py` line 318 `KeyError: 'position'` (source bug).** `_arrange_views()`
returns view dicts keyed `ox`/`oy`, but the layout map read a non-existent `position` key —
crashed the diagram on any platform. Fixed to `{v["name"]: (v["ox"], v["oy"]) ...}`.
## Known follow-ups (deferred, out of Phase 0 scope)
- **Active-area detection is a no-op on Linux.** `external_diagram.py` imports `OCC.Core.*`
(pythonocc-core) for active-area detection, but the loader uses build123d's `OCP` kernel.
The import fails and is caught (logged as a warning) — the diagram still renders, just
without the auto-detected active-area dimension. Porting `OCC` → `OCP` is a Phase 1 task.
- **Pin to the lockfile for reproducible Unraid builds.** `requirements.lock.txt` is frozen;
switch the Dockerfile's `COPY requirements.txt` / install line to it when convenient.
- **FreeCAD fallback is macOS-only right now.** `skill.src/modules/loader.py` hardcodes
`/Applications/FreeCAD.app/...`, so on Linux the fallback no-ops and returns `None`.
build123d is the primary path and should handle the samples; wiring a Linux
`freecadcmd` fallback means editing `loader.py` and is left for later.
- **Lockfile.** Replace the floor pins with `requirements.lock.txt` once the build is green.
- **OSMesa is CPU rendering.** Fine for correctness validation; thumbnail speed on the
~25 MB sample assemblies is a Phase 1+ concern. The roadmap's recommended pivot —
export GLB and render client-side with three.js — sidesteps server GL for the live viewer.

# STEP Processor Skill — Project Context
### CoWork Memory Document · MPMedia Engineering
**Updated:** June 2026 · **Status:** ✅ FULLY TESTED — Smoke-tested on 3 Chinese-sourced STEP files
---
## What This Is
A Python-based CAD processing skill for MPMedia's engineering workflow. Reads STEP/STP files (display enclosures, mounting kits, hardware assemblies) and automates: thumbnail generation, parts BOM export (MPM-branded Excel), Chinese-to-English label translation, STEP file rewriting with English labels, geometric queries, and external dimensional diagram creation.
Lives as a CoWork skill folder with a `SKILL.md`. Callable from Claude or directly from CLI.
---
## Current Working State (as of June 2026)
### Smoke Test Results
All three production STEP files tested end-to-end:
| File | Faces | Parts (STEP parser) | Translations | _EN.step |
|------|-------|---------------------|--------------|----------|
| MR16s Gen1 | 5,655 | 28 | 16/16 | ✅ All English |
| MR27s Gen1 | 6,732 | 31 | 18/18 | ✅ All English |
| MR28uws Gen1 | 5,891 | 31 | 20/20 | ✅ All English |
### What Works
- **STEP loading**: build123d primary, FreeCAD headless fallback
- **GBK encoding**: Chinese CAD files fully decoded (see Architecture Notes below)
- **BOM extraction**: STEP text parser as primary source — correctly reads Chinese names
- **Translation**: Claude API (`claude-haiku-4-5-20251001`) — batched, single call per file
- **STEP rewriter**: `_EN.step` produced with English labels in both PRODUCT name fields
- **BOM export**: MPM-branded `.xlsx` (Montserrat/Open Sans, Dark Shade header, Gold border, alternating rows)
- **Thumbnails**: 6 PNG views via pyrender (front, rear, left, right, iso_left, iso_right)
### BOM Output Format
Columns in Excel output order:
| Column | Header in Excel |
|--------|----------------|
| part_number | Part # |
| part_description | Part Description |
| quantity | Qty |
| level | Level |
| parent | Parent |
| bbox_x_mm | X (mm) |
| bbox_y_mm | Y (mm) |
| bbox_z_mm | Z (mm) |
| notes | Notes |
| part_name_supplier | Supplier Part Name |
`part_description` = translated English name (was `part_name_english` internally).
`part_name_supplier` = original Chinese name from supplier file (last column, was `part_name_original`).
---
## Architecture Notes (Critical — Read Before Debugging)
### GBK Encoding Fix
STEP files from Chinese CAD tools (SolidWorks CN, etc.) embed raw GBK bytes in `PRODUCT` entity name strings. This caused two separate problems, each with a different fix:
**Problem 1: BOM shows garbled Chinese (mojibake)**
OpenCASCADE (OCC) / build123d's STEP reader applies an internal codec that maps each 2-byte GBK sequence to incorrect Unicode codepoints. This is NOT reversible via latin-1 → GBK round-trip because OCC's codec is not latin-1.
Fix: Bypass OCC entirely for part name extraction. `bom.py` reads the raw STEP file text directly with encoding detection (UTF-8 → GBK → latin-1 fallback) and parses `PRODUCT` entities via regex. This is the primary name source; OCC assembly walk is fallback only.
**Problem 2: _EN.step still shows Chinese in CAD viewer**
The rewriter (`rewriter.py`) was reading the file as UTF-8, turning GBK bytes into replacement chars (U+FFFD). Chinese names became `???` and never matched the translation map.
Fix: `rewriter.py` uses the same encoding-detection reader as `bom.py`. File is read as GBK when UTF-8 produces replacement chars.
**Problem 3: Only first PRODUCT name field was replaced**
ISO 10303-21 `PRODUCT` entity format: `#N = PRODUCT('id', 'name', 'description', (#...))`. Both the first and second quoted strings carry the part name. CAD viewers (including OpenCASCADE CAD Assistant) display the second field.
Fix: Updated `PRODUCT_PATTERN` regex to capture both fields with 5 groups. Replacement writes the translated name into both positions.
### Translation API Model
Current model: `claude-haiku-4-5-20251001`
Previous value `claude-sonnet-4-20250514` was returning 404 — updated in `translator.py`.
### BOM Excel Library
`openpyxl` must be installed in the venv. The skill falls back to CSV silently if it's missing — don't rely on this fallback, install it explicitly.
---
## Prerequisites for a New macOS Computer
### Hardware Requirements
- Apple Silicon Mac (M1/M2/M3/M4) — all wheels are native arm64
- **No Rosetta required**
- macOS 13 Sequoia or later recommended
### Software Stack
```
Python 3.10–3.12 (3.13 works but less tested; 3.9 too old)
Homebrew (for cairo system libs)
~/step-processor-env (Python venv — all pip packages go here)
```
### Python Packages (pip install in venv)
```bash
pip install cadquery-ocp # OCC kernel, native arm64, ~300MB
pip install build123d # STEP loader, primary
pip install trimesh pyrender # thumbnail rendering pipeline
pip install Pillow numpy pandas # image and data processing
pip install anthropic # Claude API client
pip install openpyxl # Excel BOM output — REQUIRED
pip install cairosvg # SVG→PNG/PDF for diagrams (optional, diagrams only)
```
### System Libraries (Homebrew)
```bash
brew install cairo pango gdk-pixbuf libffi # required for cairosvg
```
### FreeCAD Fallback (Optional)
Only needed if build123d fails on a specific file.
- Download official arm64 `FreeCAD.app` from https://github.com/FreeCAD/FreeCAD/releases/latest
- Drag to `/Applications`, launch once so macOS approves it
- Verify: `/Applications/FreeCAD.app/Contents/Resources/bin/freecadcmd --version`
> **macOS 15 Sequoia:** conda-forge FreeCAD is killed by Gatekeeper. Use the official signed `.app` only.
### Anthropic API Key
The key must be available in the environment where the processor runs.
**For interactive terminal use:**
```bash
echo 'export ANTHROPIC_API_KEY="sk-ant-YOUR-KEY"' >> ~/.zshrc
source ~/.zshrc
```
**For Desktop Commander / CoWork (non-interactive shell):**
```bash
echo 'export ANTHROPIC_API_KEY="sk-ant-YOUR-KEY"' >> ~/.zshenv
```
`~/.zshrc` is only sourced in interactive shells. Desktop Commander spawns non-interactive zsh — it reads `~/.zshenv` instead. **Both files should have the key.**
---
## Setup — Fast Path (New Mac)
```bash
# 1. Create venv
python3 -m venv ~/step-processor-env
source ~/step-processor-env/bin/activate
# 2. Install all packages
pip install --upgrade pip
pip install cadquery-ocp build123d trimesh pyrender Pillow numpy pandas anthropic openpyxl
# 3. System libs for diagram export
brew install cairo pango gdk-pixbuf libffi
pip install cairosvg
# 4. API key (do BOTH for interactive + Desktop Commander)
echo 'export ANTHROPIC_API_KEY="sk-ant-YOUR-KEY"' >> ~/.zshrc
echo 'export ANTHROPIC_API_KEY="sk-ant-YOUR-KEY"' >> ~/.zshenv
source ~/.zshrc
# 5. Verify
python -c "import build123d, openpyxl, anthropic, trimesh; print('ALL OK')"
# 6. Test run
cd /path/to/step-skill-folder
python step_processor.py yourfile.step --no-thumbnails --verbose
```
Expected output for Chinese STEP file:
```
INFO [build123d] Loaded: yourfile.step | NNNN faces | NN parts
INFO STEP text parser found NN unique part names
INFO BOM extracted: NN parts
INFO BOM XLSX → yourfile_bom.xlsx
INFO Chinese part names detected — auto-translating
INFO API returned NN translations
INFO _EN.step written: yourfile_EN.step (NN labels replaced)
```

## Known Issues and Pending Work
### BOM bbox Enrichment (partial)
Rows beyond the first only get 5.0 × 5.0 × 5.0mm placeholder bounding boxes. The OCC child enumeration only retrieves the top-level shape's children correctly. Root cause: build123d's `.children` on compound shapes doesn't walk sub-assemblies for bbox. Fix: map part names from STEP text parser back to OCC children by label — non-trivial due to OCC label mangling on CJK files.
### Mounting Hole Filter — Minimum Diameter
The query engine's mounting hole detector returns PCB vias (0.4mm diameter) alongside actual mounting holes. Needs a minimum diameter threshold (recommend 2.0mm floor). Pending update to `query_engine.py`.
### Phase 7 Full Test
The SETUP_CHECKLIST.md Phase 7 tests have been validated for Tests 1, 2, 4 (BOM, translation, rewrite). Tests 3 (thumbnails), 5 (REPL), 6/7 (diagrams) not yet re-run post GBK fix. Thumbnails were verified in an earlier session; diagram code is scaffolded but output quality against production files not fully validated.
### Conda freecad_env Cleanup
From a prior session: `conda activate freecad_env && conda deactivate && conda env remove -n freecad_env`. The conda FreeCAD approach was abandoned in favor of the signed FreeCAD.app. This env is dead weight on the local machine.

## Library Stack Decision Log
| Decision | Choice | Reason |
|----------|--------|--------|
| CAD kernel | build123d | Native arm64 arm; clean API; same OCC as existing viewer |
| Fallback CAD | FreeCAD.app (signed) | conda-forge builds killed by Gatekeeper on Sequoia |
| Translation | Claude Haiku API | Batched, manufacturing-context prompted, flags ambiguity |
| Diagrams | SVG-first + cairosvg | No GUI dependency; vector quality; cairosvg handles PNG/PDF |
| Excel | openpyxl | MPM brand formatting, column control, frozen panes |
| Rejected | pythonocc | Rosetta/x64 conda dependency — non-starter on Apple Silicon |
| Rejected | conda-forge FreeCAD | Unsigned binaries killed by Gatekeeper on macOS 15 |
---
## Planned Integration Points
- **Odoo V18 MRP**: Model number from `meta.json` triggers lookup of weight, BOM cost, stock status
- **CoWork product docs**: `meta.json` feeds product data cards; diagram PNGs embed in Knowledge Base articles
- **RDMC** (`rdmc.messagepoint.tv`): Thumbnail PNGs for display inventory visual reference
- **OnSign.tv**: Enclosure dimensions for content sizing reference

# INSTALL.md — STEP Processor Setup (Apple Silicon / macOS arm64)
No Rosetta. No x64 sub-environments. Both libraries run natively.
---
## 1. build123d (Primary — native arm64, pip-based)
build123d depends on `cadquery-ocp`, which ships native arm64 wheels
via GitHub Releases (not yet on PyPI, but stable).
### Step 1 — Install the arm64 OCP wheel
Go to: https://github.com/CadQuery/OCP/releases
Download the wheel matching your Python version, e.g.:
`cadquery_ocp-7.x.x-cp311-cp311-macosx_12_0_arm64.whl`
Install it:
```bash
pip install /path/to/cadquery_ocp-*.whl
```
### Step 2 — Install build123d and rendering stack
```bash
pip install build123d
pip install trimesh pyrender Pillow numpy pandas anthropic
```
### Step 3 — Set API key
```bash
export ANTHROPIC_API_KEY=sk-ant-...
# Add to ~/.zshrc to persist
```
### Step 4 — Verify
```bash
python -c "import build123d; print('build123d OK')"
python -c "import trimesh; print('trimesh OK')"
python -c "import pyrender; print('pyrender OK')"
```
---
## 2. FreeCAD Headless (Fallback — native arm64 via conda-forge)
FreeCAD has been available as a native macOS-arm64 conda-forge package
since late 2024. Install it in its own conda environment to avoid
dependency conflicts with build123d.
### Step 1 — Install Miniforge (arm64) if not already present
Download from: https://github.com/conda-forge/miniforge/releases
Select: `Miniforge3-MacOSX-arm64.sh`
```bash
bash Miniforge3-MacOSX-arm64.sh
```
### Step 2 — Create FreeCAD environment
```bash
conda create -n freecad_env python=3.11
conda activate freecad_env
conda install -c conda-forge freecad
```
### Step 3 — Verify headless operation
```bash
FreeCADCmd --version
# or
python -c "import FreeCAD; import Part; print('FreeCAD headless OK')"
```
**Important:** Never import `FreeCADGui` in headless scripts — it will crash.
### Step 4 — Make FreeCAD importable from your build123d environment
Add the FreeCAD conda env's site-packages to your PATH, or run scripts
via the conda freecad_env directly:
```bash
conda run -n freecad_env python step_processor.py myfile.step
```
---
## Quick Test
Once either library is installed:
```bash
# Test with a sample STEP file
python step_processor.py sample.step --verbose
# Test query REPL
python step_processor.py sample.step --repl
```
---
## Dependency Summary
| Package | Purpose | Required for |
|---------------|--------------------------------|---------------------|
| build123d | STEP loading + geometry | Primary path |
| cadquery-ocp | OCC kernel (arm64 wheel) | build123d |
| trimesh | Mesh handling for rendering | PNG thumbnails |
| pyrender | Offscreen rendering | PNG thumbnails |
| Pillow | PNG file writing | PNG thumbnails |
| numpy | Geometry math | Both paths |
| pandas | BOM CSV output | BOM export |
| anthropic | Claude API translation | Translation |
| FreeCAD | Fallback STEP loading | Fallback path only |
---
## 3. cairosvg (required for PNG and PDF export from diagrams)
```bash
pip install cairosvg
# On macOS, may also need:
brew install cairo pango gdk-pixbuf libffi
```
Verify:
```bash
python -c "import cairosvg; print('cairosvg OK')"
```

# STEP Processor — macOS Setup Checklist
### Apple Silicon (Mac Studio M-series) · No Rosetta Required
Work through this top to bottom. Each section has a ✅ verification command
so you know it worked before moving on.
---
## PHASE 1 — Prerequisites
### 1.1 — Confirm Python version
```bash
python3 --version
```
**You need Python 3.10, 3.11, or 3.12.**
3.13 will work but is less tested. 3.9 is too old.
If your version is wrong, install via Homebrew:
```bash
brew install python@3.11
```
Then use `python3.11` explicitly in all commands below.
---
### 1.2 — Confirm Homebrew is installed
```bash
brew --version
```
If missing:
```bash
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
```
---
### 1.3 — Create a dedicated virtual environment
Keep everything isolated from your system Python.
Pick a folder — e.g. your CoWork dev directory.
```bash
python3 -m venv ~/step-processor-env
source ~/step-processor-env/bin/activate
```
You should see `(step-processor-env)` in your terminal prompt.
**All pip commands below assume this environment is active.**
✅ Verify:
```bash
which python # should point inside step-processor-env
```
---
## PHASE 2 — Primary Library: build123d
### 2.1 — Upgrade pip first
```bash
pip install --upgrade pip
```
---
### 2.2 — Install cadquery-ocp (the OCC kernel, native arm64)
This is now on PyPI directly — no manual wheel download needed.
```bash
pip install cadquery-ocp
```
This is a large download (~300MB). Let it run.
✅ Verify:
```bash
python -c "import OCP; print('OCP kernel OK')"
```
---
### 2.3 — Install build123d
```bash
pip install build123d
```
✅ Verify:
```bash
python -c "import build123d; print('build123d OK')"
```
---
### 2.4 — Install the rendering stack
```bash
pip install trimesh pyrender Pillow numpy pandas anthropic openpyxl
```
> **Note:** `openpyxl` is required for Excel BOM output. If missing, the skill silently
> falls back to CSV. Install it here to get MPM-branded `.xlsx` output.
✅ Verify each:
```bash
python -c "import trimesh; print('trimesh OK')"
python -c "import pyrender; print('pyrender OK')"
python -c "import PIL; print('Pillow OK')"
python -c "import pandas; print('pandas OK')"
python -c "import anthropic; print('anthropic OK')"
python -c "import openpyxl; print('openpyxl OK')"
```
---
## PHASE 3 — Diagram Export: cairosvg
Required for converting SVG diagrams to PNG and PDF.
### 3.1 — Install system libraries via Homebrew
```bash
brew install cairo pango gdk-pixbuf libffi
```
### 3.2 — Install cairosvg
```bash
pip install cairosvg
```
✅ Verify:
```bash
python -c "import cairosvg; print('cairosvg OK')"
```
If you get a library not found error, run this and retry:
```bash
export PKG_CONFIG_PATH="/opt/homebrew/lib/pkgconfig"
pip install cairosvg
```
---
## PHASE 4 — Fallback Library: FreeCAD Headless
Only needed if build123d fails on a specific file.
> **macOS 15 Sequoia note:** The conda-forge FreeCAD package is killed silently
> by Gatekeeper on Sequoia due to unsigned binaries. Use the official signed
> FreeCAD.app instead (approach below). Conda approach will NOT work on Sequoia.
### 4.1 — Install official FreeCAD.app (signed & notarized)
Download the latest arm64 release from:
```
https://github.com/FreeCAD/FreeCAD/releases/latest
```
Open the .dmg and drag FreeCAD.app to /Applications as normal.
Launch it once from /Applications so macOS registers the security approval.
### 4.2 — Verify headless via app bundle
The binary is `freecadcmd` (all lowercase) inside the bundle:
```bash
/Applications/FreeCAD.app/Contents/Resources/bin/freecadcmd --version
# Should print: FreeCAD 1.x.x Revision: ...
```
✅ Verify Python import:
```bash
/Applications/FreeCAD.app/Contents/Resources/bin/python -c \
"import sys; sys.path.insert(0, '/Applications/FreeCAD.app/Contents/Resources/lib'); \
import FreeCAD; print('FreeCAD', FreeCAD.Version())"
```
**Key paths for loader.py:**
- CLI binary: `/Applications/FreeCAD.app/Contents/Resources/bin/freecadcmd`
- Python interpreter: `/Applications/FreeCAD.app/Contents/Resources/bin/python`
- Module path (add to sys.path): `/Applications/FreeCAD.app/Contents/Resources/lib`
The code invokes FreeCAD using the bundle's own Python — no conda env needed.
---
## PHASE 5 — API Key
### 5.1 — Set your Anthropic API key
```bash
echo 'export ANTHROPIC_API_KEY="sk-ant-YOUR-KEY-HERE"' >> ~/.zshrc
echo 'export ANTHROPIC_API_KEY="sk-ant-YOUR-KEY-HERE"' >> ~/.zshenv
source ~/.zshrc
```
> **Important:** Add the key to **both** `~/.zshrc` AND `~/.zshenv`.
> `~/.zshrc` is only sourced in interactive terminal sessions.
> `~/.zshenv` is sourced for all zsh invocations including Desktop Commander's
> non-interactive shells — without it, translation will silently fail when
> running via CoWork/Desktop Commander.
✅ Verify:
```bash
echo $ANTHROPIC_API_KEY # should print your key (or at least sk-ant-...)
```
---
## PHASE 6 — Place the Skill Files
### 6.1 — Copy the step-processor folder to your working location
Recommended: somewhere in your CoWork project or a dedicated tools directory.
```
~/your-project/
step-processor/
step_processor.py
modules/
__init__.py
loader.py
bom.py
renderer.py
translator.py
rewriter.py
query_engine.py
external_diagram.py
schemas/
external_diagram_schema.json
parts_mapping_schema.json
templates/
datablock_template.md
SKILL.md
INSTALL.md
```
### 6.2 — Activate your environment before running
```bash
source ~/step-processor-env/bin/activate
cd ~/your-project/step-processor
```
---
## PHASE 7 — Test Run (do this when you have a STEP file ready)
Work through these tests in order. Stop at the first failure and fix it
before continuing.
---
### TEST 1 — Confirm the skill loads without errors
```bash
python step_processor.py --help
```
Expected: prints the CLI help/usage block with no ImportError or traceback.
---
### TEST 2 — Load a STEP file and extract BOM
Replace `yourfile.step` with your actual file path.
```bash
python step_processor.py /path/to/yourfile.step --no-thumbnails --verbose
```
Expected output:
```
INFO Loading: yourfile.step
INFO [build123d] Loaded: yourfile.step
INFO BOM extracted: N parts
INFO BOM XLSX → /path/to/yourfile_bom.xlsx
```
Open the `.xlsx` file to confirm part names look right.
If you see Chinese characters in the `Supplier Part Name` column — that's expected and correct.
The `Part Description` column will be populated with English in Test 4.
If you see a CSV instead of xlsx, `openpyxl` is not installed — run `pip install openpyxl`.
---
### TEST 3 — Generate thumbnails
```bash
python step_processor.py /path/to/yourfile.step --no-bom --verbose
```
Expected: 6 PNG files appear next to the STEP file:
`yourfile_front.png`, `yourfile_bottom.png`, `yourfile_left.png`,
`yourfile_right.png`, `yourfile_iso_left.png`, `yourfile_iso_right.png`
Open them in Preview to confirm they look like your enclosure from different angles.
---
### TEST 4 — Translation (requires API key)
Only run this if the BOM from Test 2 has Chinese part names.
```bash
python step_processor.py /path/to/yourfile.step --no-thumbnails --translate --verbose
```
Expected: `part_name_english` column in the CSV is now populated with English names.
A `yourfile_EN.step` should appear if Chinese labels were found in the STEP file itself.
---
### TEST 5 — Geometry query REPL
```bash
python step_processor.py /path/to/yourfile.step --no-thumbnails --no-bom --repl
```
At the `>` prompt, try:
```
> bounding box
> list all holes
> all parts
> help
> exit
```
Confirm the output tables look reasonable for your file.
---
### TEST 6 — External dimensional diagram
```bash
python step_processor.py /path/to/yourfile.step --diagram --verbose
```
Expected files next to the STEP:
- `yourfile__external-diagram.svg`
- `yourfile__external-diagram.png`
- `yourfile__meta.json`
Open the SVG in a browser (drag and drop into Safari or Chrome) to inspect the diagram.
Open the PNG for the rasterized version.
Open the JSON to confirm the metadata block populated correctly.
---
### TEST 7 — Diagram with PDF output
```bash
python step_processor.py /path/to/yourfile.step --diagram --diagram-pdf --verbose
```
Expected: adds `yourfile__external-diagram.pdf` to the outputs.
Open in Preview to confirm it renders cleanly.
---
## Quick Reference — Re-activating After Restart
Every time you open a new terminal session:
```bash
source ~/step-processor-env/bin/activate
cd ~/your-project/step-processor
export ANTHROPIC_API_KEY="sk-ant-..." # only if not already in ~/.zshrc
```
---
## Troubleshooting Quick Reference
| Symptom | Fix |
|---------|-----|
| `ModuleNotFoundError: build123d` | `pip install build123d` (check env is activated) |
| `ModuleNotFoundError: OCP` | `pip install cadquery-ocp` |
| `ModuleNotFoundError: cairosvg` | `brew install cairo && pip install cairosvg` |
| `pyrender` offscreen crash | Expected on some macOS setups — thumbnails will warn but diagram still generates |
| BOM shows no parts / 1 part | Normal for single-body STEP files — the STEP text parser falls back to 1-row BOM |
| Chinese labels not translated | Check `$ANTHROPIC_API_KEY` is set. If running via CoWork/Desktop Commander, add key to `~/.zshenv` not just `~/.zshrc` |
| BOM output is CSV not xlsx | `openpyxl` not installed — `pip install openpyxl` with venv active |
| `_EN.step` entity count mismatch warning | File has unusual STEP encoding — rewrite skipped, original untouched, BOM still correct |
| FreeCAD fallback not working | Use signed FreeCAD.app — conda-forge is Gatekeeper-blocked on Sequoia. Path: `/Applications/FreeCAD.app/Contents/Resources/bin/freecadcmd` (all lowercase) |
| Diagram SVG opens blank | Check `yourfile__meta.json` warnings array for geometry errors |

# STEP File Processor Skill
## Purpose
This skill enables Claude to work with STEP/STP CAD files used in manufacturing.
It provides:
- PNG thumbnail extraction at 6 camera angles
- Parts manifest / BOM export to CSV with automatic Chinese→English translation
- Optional English-labeled STEP copy (source file never modified)
- Natural language geometric query interface (holes, faces, dimensions, quantities)
Designed for MPMedia's display enclosure and mounting kit product lines.
---
## When to invoke this skill
Trigger on any of:
- User provides a `.step` or `.stp` file path and asks to process, view, extract, or query it
- User asks to "generate thumbnails" or "render views" of a STEP file
- User asks to "extract BOM", "get parts list", or "show manifest" from a STEP file
- User asks a geometric question about a STEP file: holes, faces, dimensions, quantities
- User asks to "translate" a STEP file's part names
- Claude Code context where a STEP file is present in the working directory
**Read this entire SKILL.md before writing any code.**
---
## Library Stack
### Primary: build123d
- Modern OpenCASCADE Python wrapper; native Apple Silicon arm64 wheels
- Clean, Pythonic API for STEP reading, assembly traversal, geometry queries
- Offscreen PNG rendering via: build123d → export GLB/OBJ → trimesh → pyrender
- Install: `pip install build123d trimesh pyrender pillow numpy pandas anthropic`
- ARM64 OCP wheel required first — see INSTALL.md
### Fallback: FreeCAD headless
- Native macOS-arm64 build available via conda-forge (verified Nov 2024)
- Used when build123d fails to load or render a specific file
- Invoked via subprocess calling `FreeCADCmd` or by importing `FreeCAD` + `Part`
- **Never import FreeCADGui** — headless only, GUI modules will crash
- Install: `conda install -c conda-forge freecad` (arm64 native, no Rosetta)
### Translation: Claude API (claude-sonnet-4-20250514)
- Translates Chinese part names with manufacturing context awareness
- e.g. 安装支架 → "Mounting Bracket" (not just "installation support")
- Requires ANTHROPIC_API_KEY in environment
### Supporting libraries (both tracks)
- `Pillow` — PNG save/compose
- `numpy` — geometry math
- `pandas` — CSV/BOM output
- `trimesh` + `pyrender` — GLB→PNG rendering fallback path
---
## File Structure
```
step-processor/
step_processor.py ← CLI entry point + REPL
modules/
loader.py ← STEP loading (build123d primary, FreeCAD fallback)
bom.py ← Assembly tree traversal + BOM extraction
renderer.py ← Offscreen PNG rendering (6 views)
translator.py ← Claude API translation layer
rewriter.py ← STEP label patcher (_EN copy only, never modifies source)
query_engine.py ← Geometric query handler (holes, faces, dimensions)
INSTALL.md
SKILL.md
```
---
## Dual-Track Fallback Pattern
Every module must implement this pattern:
```python
def load_step(filepath):
try:
return _load_via_build123d(filepath)
except ImportError:
logger.warning("build123d not available — falling back to FreeCAD")
return _load_via_freecad(filepath)
except Exception as e:
logger.warning(f"build123d failed ({e}) — falling back to FreeCAD")
return _load_via_freecad(filepath)
```
Always log fallbacks at WARNING level so the user knows which path ran.
FreeCAD fallback invocation pattern (subprocess, cleanest isolation):
```python
import subprocess, json, tempfile
def _load_via_freecad(filepath):
script = f"""
import FreeCAD, Part, json
shape = Part.read("{filepath}")
# extract data, write to temp JSON
"""
result = subprocess.run(["FreeCADCmd", "--console", "-c", script], capture_output=True)
# parse result...
```
---
## Camera Views
Always produce these 6 views unless user specifies otherwise:
| View Name | Camera Direction | File Suffix |
|------------|---------------------------|------------------|
| Front | +Y looking toward origin | `_front.png` |
| Bottom | -Z looking up | `_bottom.png` |
| Left | -X looking right | `_left.png` |
| Right | +X looking left | `_right.png` |
| Iso Left | +X+Y+Z (left-forward) | `_iso_left.png` |
| Iso Right | -X+Y+Z (right-forward) | `_iso_right.png` |
Default resolution: 1024×768. All PNGs saved to same folder as source STEP file.
---
## Output Naming Convention
Given input: `/path/to/EnclosureA.step`
| Output | Path |
|---------------------|-----------------------------------|
| Thumbnails (×6) | `/path/to/EnclosureA_front.png` etc. |
| BOM CSV | `/path/to/EnclosureA_bom.csv` |
| English STEP copy | `/path/to/EnclosureA_EN.step` |
**Never overwrite or modify the source STEP file.**
`_EN.step` is only created when Chinese labels are detected. If all labels are
already ASCII/English, skip silently and note it in output.
---
## BOM CSV Schema
```
part_number, part_name_original, part_name_english, quantity, level, parent,
bbox_x_mm, bbox_y_mm, bbox_z_mm, notes
```
- `level` = assembly depth (0 = root, 1 = direct children, etc.)
- `parent` = part_name_english of parent assembly
- `notes` = translator flags (e.g. "machine-translated", "ambiguous term")
- Bounding boxes in millimeters, 2 decimal places
- If no translation needed, `part_name_original` == `part_name_english`
---
## Translation Logic
```
bom.py extracts all part names
→ translator.py checks each name for CJK unicode range (\u4e00-\u9fff)
→ if any found: batch call Claude API with this system prompt:
"You are a mechanical engineering translator specializing in Chinese
manufacturing CAD files for display and enclosure products. Translate
the following part names from Chinese to English. Preserve technical
precision. Use standard hardware terminology. Output ONLY a JSON object
mapping original → translated, nothing else.
Example: {\"安装支架\": \"Mounting Bracket\", \"螺钉M4\": \"M4 Screw\"}"
→ inject translations into BOM CSV
→ if translation requested: produce _EN.step via rewriter.py
```
Flag uncertain translations in the `notes` column rather than silently guessing.
---
## STEP Label Rewriting (_EN copy)
`rewriter.py` produces a translated copy — line-by-line, targeted replacement:
1. Read source file line by line
2. Identify lines containing `PRODUCT('`, `PRODUCT_DEFINITION_CONTEXT(` etc.
3. Extract quoted name strings (first argument of PRODUCT entity)
4. Replace CJK strings with translated equivalents from the translation map
5. Write to `{filename}_EN.step`
6. Validate: entity `#` count before == after. If mismatch → abort, warn, delete partial output
**Do not use broad regex that could touch entity reference numbers (#123 etc.)**
Target only the quoted string arguments of known STEP entity types.
---
## Geometric Query Engine
`query_engine.py` handles natural language queries about loaded geometry.
### Supported Query Types
| Query pattern | What it extracts |
|----------------------------------|-------------------------------------------------------|
| "list all mounting holes" | Cylindrical faces, axis ⊥ to primary face, dia < 15mm|
| "list all holes" | All cylindrical through-features |
| "holes diameter [N]mm" | Filter holes by diameter |
| "tapped holes" / "threaded" | Cylinders with helical features (if present in model) |
| "face count" | Total face count by type (planar, cylindrical, etc.) |
| "bounding box" | Overall model extents in mm |
| "part [name] dimensions" | Bounding box of a specific named part |
| "largest face" | Largest planar face area in mm² |
| "wall thickness" | Min distance between opposing parallel faces |
| "all parts" | Full assembly listing with quantities |
### Query Invocation
**CLI (single query, exit after):**
```bash
python step_processor.py enclosure.step --query "list all mounting holes with diameter and depth"
```
**REPL (interactive, geometry stays loaded in memory between queries):**
```bash
python step_processor.py enclosure.step --repl
> list mounting holes
> bounding box
> how many M4 holes
> exit
```
### Query Output Format
Always return a structured table:
```
MOUNTING HOLES — EnclosureA.step
─────────────────────────────────────────────────────────────
# Part Name Diameter Depth Position (x,y,z)
─────────────────────────────────────────────────────────────
1 Front Panel 4.20 mm 8.00 mm (12.50, 0.00, 45.20)
2 Front Panel 4.20 mm 8.00 mm (87.50, 0.00, 45.20)
─────────────────────────────────────────────────────────────
Total: 8 holes across 3 parts
```
---
## CLI Reference
```
python step_processor.py <file.step> [options]
Options:
--thumbnails Generate 6 PNG views (default: on)
--no-thumbnails Skip PNG generation
--bom Export BOM CSV (default: on)
--no-bom Skip BOM export
--translate Auto-translate Chinese labels in BOM + produce _EN.step
--no-translate Skip translation even if Chinese labels detected
--query "..." Run a single geometric query and exit
--repl Enter interactive query REPL
--resolution WxH Thumbnail resolution (default: 1024x768)
--views front,iso_left,iso_right Comma-separated subset of views
--verbose Show library selection, fallback notices, timing
```
**Default behavior (no flags):** `--thumbnails --bom` plus auto-detect translation.
---
## Error Handling
| Condition | Behavior |
|------------------------------------|--------------------------------------------------------|
| File not found | Exit with clear message, no partial output |
| Neither library available | Exit with INSTALL.md reference |
| build123d render fails | Auto-fallback to FreeCAD path, log warning |
| Translation API unavailable | Write BOM with original names only, note in output |
| STEP has no assembly structure | Treat as single part, one-row BOM |
| Chinese detected, no translate flag| Auto-translate by default (skip with --no-translate) |
| _EN.step entity count mismatch | Abort rewrite, warn, delete partial file |
| FreeCAD headless GUI module import | Catch ImportError, skip that module, continue |
---
## INSTALL.md Summary
**build123d (primary — native arm64, no conda):**
```bash
# 1. Install the arm64 OCP wheel from CadQuery GitHub releases:
# https://github.com/CadQuery/OCP/releases — pick macosx_*_arm64.whl for your Python
pip install path/to/cadquery_ocp-*.whl
# 2. Install build123d and rendering stack
pip install build123d trimesh pyrender pillow numpy pandas anthropic
# 3. Set API key
export ANTHROPIC_API_KEY=sk-ant-...
```
**FreeCAD (fallback — native arm64 via conda):**
```bash
# Install Miniforge arm64 if not already present:
# https://github.com/conda-forge/miniforge/releases
conda install -c conda-forge freecad
# Verify headless works:
FreeCADCmd --version
```
No Rosetta. No x64 sub-environment. Both libraries run natively on Apple Silicon.
---
## Notes for Claude
- Default run = thumbnails + BOM + auto-translate if Chinese detected
- When a user asks a geometry question, invoke query_engine — don't describe the STEP file from the BOM alone
- Always confirm output file locations at end of run
- If Chinese labels found, proactively note it and offer to show the translation map
- In REPL mode, keep responses tight — it's a terminal session
- When describing holes or geometry, lead with the table, not prose
- If build123d fallback fires, tell the user which library ran
---
## Sub-skill: External Dimensional Diagram
### Purpose
Generates a standardized external dimensional diagram for installation planning,
product reference, and non-CAD users. NOT a manufacturing drawing.
Think: installation reference sheet with clean orthographic views + one ISO.
### Terminology
Use: "external dimensional diagram"
Never use: shop drawing, manufacturing drawing, fabrication drawing
### Entry point
```python
from modules.external_diagram import step_external_diagram
meta = step_external_diagram(
path="enclosure.step",
mode="enclosure_only", # or enclosure_plus_mounting, mounting_only
mapping_file="MR28UW_mapping.json", # optional
datablock_file="MR28UW.md", # optional, auto-detected if omitted
options={
"style": "line_drawing", # or "rendered" — auto if omitted
"pdf": True, # default False
"mounting_variant": "Wall Mount", # for enclosure_plus_mounting mode
"render_variants": True, # generate diagram per mounting variant
}
)
```
### Modes
- `enclosure_only` — enclosure body only (default when no mapping file)
- `enclosure_plus_mounting` — enclosure + selected mounting subassembly
- `mounting_only` — mounting geometry only
### Styles
- `line_drawing` — pure SVG wireframe (MR28 reference style). Auto-selected for simple enclosures.
- `rendered` — rendered ISO views composited with dimensioned orthographic line views
(MR16 reference style). Auto-selected for complex assemblies (>200 faces).
### Layout auto-selection
- `single_sheet` — default for most models
- `multi_page` — auto-selected when any dimension > 1200mm or part count > 60
### Outputs per run
| File | Always? | Description |
|------|---------|-------------|
| `{stem}__external-diagram.svg` | Yes | Source SVG, always retained |
| `{stem}__external-diagram.png` | Yes | PNG export via cairosvg |
| `{stem}__external-diagram.pdf` | Optional (`--pdf` flag) | PDF via cairosvg |
| `{stem}__meta.json` | Yes | Full metadata per schema |
| Individual view PNGs | Rendered style only | front, side, rear, iso |
| Variant diagrams | If `render_variants=True` | One set per mounting variant |
### Dimensions shown
Required: overall width, height, depth
Auto-detected and shown when found:
- Active area / screen aperture (with diagonal in mm and inches)
- Mounting hole chain spacing (horizontal or vertical, auto-selected by readability)
- VESA pattern if detected
- Edge offsets to mounting geometry
Units: metric primary (mm) with imperial in parentheses, smaller italic
### Parts mapping file
JSON file per product model — classifies parts as enclosure/mounting/internal/fastener.
Drives show/hide logic per mode. Supports mounting variants.
Schema: `schemas/parts_mapping_schema.json`
Example: `schemas/parts_mapping_schema.json` → `examples` array
### Datablock / title block
Sourced from a `.md` file alongside the STEP file (auto-detected by matching stem name)
or passed explicitly as `datablock_file`.
Template: `templates/datablock_template.md`
Edit the template to configure: model number, display name, revision, date, company,
and any custom fields. Custom fields appear in the data block footer.
### Metadata schema
Full JSON schema: `schemas/external_diagram_schema.json`
Designed for AI consumption, Odoo product data integration, search indexing,
and CoWork documentation workflows. All geometry in mm.
### CLI
```bash
# Basic — enclosure only, auto style
python step_processor.py enclosure.step --diagram
# With options
python step_processor.py enclosure.step --diagram --diagram-mode enclosure_plus_mounting \
--diagram-style line_drawing --diagram-pdf \
--mapping mapping/MR28UW_mapping.json \
--datablock MR28UW.md
# Render all mounting variants
python step_processor.py enclosure.step --diagram --diagram-mode enclosure_plus_mounting \
--diagram-variants
```
### Notes for Claude
- When a user says "generate a diagram", "make a dimensional sheet", or "create reference drawing" → invoke this sub-skill
- Always confirm mode with user if unclear (enclosure_only vs with mounting)
- If no mapping file exists, default to enclosure_only and note it
- If multiple mounting variants detected in assembly tree, offer to render each
- The meta.json output is the primary artifact for downstream AI/workflow consumption
- cairosvg is required for PNG/PDF export: `pip install cairosvg`
- Weight/mass fields in meta.json are reserved for future Odoo product data integration

The STEP text parser is always the primary source for part_name_original.
It reads raw bytes with GBK/UTF-8 encoding detection, correctly decoding
Chinese CAD part labels.
OCC's STEP reader (used by build123d) applies an internal codec that maps
each 2-byte GBK sequence to an incorrect Unicode codepoint — the resulting
strings cannot be recovered. We therefore never rely on child.label for
part names when the file may contain CJK characters.
OCC assembly walk (_bom_from_parts) is kept as a fallback only for files
where the text parser returns nothing (e.g., non-PRODUCT-entity STEP files).

renderer.py — Offscreen PNG thumbnail generation.
Pipeline (with color): build123d → GLTF export → trimesh scene → pyrender → PNG
Pipeline (fallback): build123d → per-solid STL → colored trimesh scene → pyrender → PNG
Coordinate convention AFTER STEP→GLTF export→trimesh load:
trimesh applies a Z-up→Y-up GLTF convention that swaps STEP's Y and Z axes:
X = width (~248mm for MR16) — left/right
Y = depth (~41mm for MR16) — front/back; Y_min=screen face, Y_max=back panel
Z = height (~459mm for MR16) — tall axis; Z_min=top end, Z_max=bottom end
→ "front" camera sits at -Y (screen side) looking toward +Y to see the LCD face.
→ World "up" vector is (0,0,-1) — negative Z = top of display in image.
