SolidWorks Automation Skill is a Python toolkit that connects coding-agent tools to the SolidWorks API for automating CAD work. Engineers use it with SolidWorks and, for some workflows, AutoCAD through a skill package, MCP server, or desktop application. The catalogue add-ons provide workflows that operate this toolkit.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00151 | $0.03986 |
| Opus 5.5 | $0.00060 | $0.01594 |
| Sonnet 5.5 | $0.00030 | $0.00797 |
| Haiku 4.5 | $0.00015 | $0.00399 |
Grade A, and why
autocad-automation scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

AutoCAD 自动化技能
本目录作为
solidworks-automation-skill的 AutoCAD/DWG 子技能使用。父技能负责 SolidWorks 建模、装配、工程图和三维导出；本子技能负责 AutoCAD 二维 DWG/DXF 绘制、批量改图、线稿矢量化、出图预览和图纸自检。涉及 SolidWorks 原生零件/装配体建模时回到父技能，涉及 AutoCAD 图纸或 DWG/DXF 时读取本子技能。
目标
让代理在本机 Windows 桌面环境中可靠控制 AutoCAD，而不是每次凭记忆临时拼命令。默认路线是 Python + COM/ActiveX，但原生写入必须先通过 capabilities.yaml 门禁和本机真机回归；当前 AutoCAD 2024 的 Documents/Layers/SelectionSets 动态代理不稳定，因此 COM 原生 DWG 绘图按 not_implemented 处理。DXF 无头读取、预览和结构审查可直接使用。AutoCAD 2024 .NET 白名单后端已连续通过真实 DWG 保存重开、PDF/PNG 和实体/图层/尺寸回归，运行时证据完整时为 verified；只允许固定命令，不得推广成任意代码执行。
适用场景
使用本技能处理：
- 新建或修改 DWG/DXF 图纸，绘制线、圆、圆弧、多段线、矩形、文字、块、图层和简单标注。
- 批量打开 DWG，检查图层、实体数量、文字、块参照、外部参照或输出文件。
- 让 Codex 直接连接本机 AutoCAD、保存 DWG、导出 DXF/PDF，并生成复核报告。
- 编写 AutoLISP、
.scr命令脚本或 C# AutoCAD .NET 插件。 - 需要查 Autodesk 官方 API、ADN/GitHub 示例、ObjectARX SDK 或 APS Design Automation 模式。
不要把本技能用于纯渲染效果图、BIM/Revit 模型、机械 STEP-first 建模、CAM 刀路或工程认证结论；这些需求优先转给相应 CAD、BIM、仿真或制造流程。
默认假设
- 操作系统：Windows。
- AutoCAD：用户本机已安装，最好已手动启动一次完成 COM 注册。
- 自动化入口：
AutoCAD.ApplicationCOM ProgID。 - 可视化默认：新建绘图任务默认先显示并激活 AutoCAD，再逐步落图元；只有批处理或用户明确要求提速时才关闭。
- 绘图单位：默认按毫米理解；AutoCAD 数据库本身是无单位数值，必须在图纸说明中记录单位。
- 空间：几何默认进入 ModelSpace；版面、标题栏和打印配置单独处理。
- 坐标：默认 WCS，二维对象使用
Z=0。 - 输出：优先保存 DWG，同时按用户需求导出 DXF/PDF；所有输出路径使用绝对路径。
- 文件安全：修改既有 DWG 前先另存副本，除非用户明确允许覆盖。
缺少版本、单位、图纸标准、输出路径或是否允许覆盖时，先做一次简短确认。简单草图可以直接假设毫米、ModelSpace、新建 DWG，并在结果中说明。
入口自检
执行 AutoCAD 自动化前先运行：
python subskills\autocad-automation\scripts\acad_preflight.py
如果用户允许自动启动 AutoCAD：
python subskills\autocad-automation\scripts\acad_preflight.py --launch
自检失败时：
- 缺
pywin32：提示用户安装python -m pip install pywin32，得到明确同意后再安装。 - 找不到 AutoCAD COM：提示用户安装 AutoCAD、启动一次 AutoCAD，或确认安装的是 LT/受限环境。
- AutoCAD 已运行但无活动文档：可以新建文档，不要误判为连接失败。
核心工作流
- 分类任务：判断是新建图纸、修改既有 DWG、批处理、出图导出、API 开发、插件开发还是故障排查。
- 确认关键约束：单位、版本、目标文件、输出格式、是否允许覆盖、图层/线型/标注标准、是否需要按企业模板绘图。
- 运行自检：先用
acad_preflight.py确认 Python COM 和 AutoCAD 状态。 - 查证 API：未封装 API 必须先读
references/api-lookup.md，再查 Autodesk 官方文档或可信 GitHub 示例；不要猜长参数、枚举值和命令行为。 - 制定绘图计划：写明图层、坐标基准、对象清单、尺寸、文本、输出路径和复核点。
- 先把软件拉起来：连接或启动 AutoCAD，确保窗口可见并尽量切到前台，再开始落图。
- 优先复用脚本：简单几何用
scripts/acad_draw.py的 JSON 输入；复杂逻辑用scripts/acad_session.py组合 COM 调用。 - 串行执行 COM：AutoCAD 桌面 COM 操作不要并行；一个脚本连接、逐步绘制、保存、复核后退出。
- 保存和导出：保存 DWG/DXF/PDF 前确保目录存在；修改原图时保留备份或另存。
- 复核结果：运行
scripts/acad_review.py统计实体、图层、包围盒和目标文件；再运行scripts/acad_preview.py导出 AutoCAD 原生 BMP/PNG 预览，并用图片查看工具做视觉审查。窗口截图可作为补充，但若被其它窗口遮挡，不可作为通过依据。 若输入是 DXF 且只需无头只读检查，可先运行scripts/acad_headless.py；它不支持 DWG 写入，最终 DWG/PDF 仍须走 AutoCAD COM。 - 沉淀经验：遇到新坑、命令差异、版本限制或稳定封装，补进
references/troubleshooting.md或脚本。

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
