What it does

This skill provides practical, scriptable guidance and helpers for automating SolidWorks via Python COM. It explains connecting to a running SolidWorks instance, common workflows for part modeling, assemblies, drawings, file export (STEP/STL/PDF), and handling units, selections, and by-ref parameters. The material is aimed at automating repetitive CAD tasks, batch exports, BOM extraction, and integrating SolidWorks operations into OpenClaw workflows.

When to use it

Use this skill when you need to automate SolidWorks on a Windows machine: create parts from parametric inputs, update assemblies, produce engineering drawings, export files in bulk, or run scripted checks and simple FEA prep. Also useful for integrating SolidWorks file export into CI or headless workflows where a running SolidWorks COM server is available.

What's included

Scripts: guidance references to scripts/ modules (connection helpers, part/assembly/export helpers) described in the SKILL body (note: repository may include the actual scripts).
References: procedural notes and troubleshooting tips for units, plane names, VARIANT packaging, and selection APIs.
Instructions: step-by-step connect pattern (connect_solidworks, mm(), deg(), new_document), conversion notes (mm->m), and export verification checks.

Compatible agents

Designed for agents or automation that can run Python on Windows and call COM (Codex/Copilot/agents with exec/shell access). Works when the host has Python and pywin32 installed.

Audit Summary

SolidWorks automation skill with 14 Python scripts for controlling SolidWorks via COM (part modeling, assemblies, drawings, exports, motion studies). Comprehensive SKILL.md with detailed workflows, subskills, and MCP server integration. Scripts are well-structured with good error handling and docstrings, but most fail at import time due to inter-module dependencies and Windows-only COM requirements (pywin32/comtypes). Only sw_appearance.py ran successfully; all others hit ImportError or platform-specific dependencies.

Watch Out

Windows-only skill — requires SolidWorks + pywin32/comtypes, cannot run on Linux/macOS
Most scripts use relative imports that fail when run outside the package context
sw_preflight.py prompts for Y/N before installing dependencies — not suitable for headless/CI environments
validate_skill.py expects a full repo structure (mcp-server/, examples/, references/) not present in the scripts bundle
MCP server (validate_mcp.py) requires 'mcp' Python package not in standard environments

Notes

Legitimate CAD automation skill. No security concerns. Code quality is good but scripts are tightly coupled and platform-locked. The skill is well-documented (in Chinese) with clear architecture — subskills for vibecad, fillet-chamfer-cnc, and threaded-holes are a nice touch. Niche but genuinely useful for SolidWorks engineers using AI agents.
