\n\n## Publisher:
\n[lgx281227231](https://clawhub.ai/user/lgx281227231)
\n\n### License/Terms of Use:
\nMIT-0
\n\n\n## Use Case:
\nDevelopers, engineers, and CAD users can use this skill to convert DWG or DXF drawings into shareable vector PDF files for viewing, printing, or exchanging drawings without CAD software.
\n\n### Deployment Geography for Use:
\nGlobal
\n\n## Known Risks and Mitigations:
\nRisk: The setup flow installs Python packages, apt packages, and an optional ODA File Converter package.
\nMitigation: Verify the ODA download source, prefer a virtual environment or isolated runtime for Python dependencies, and install system packages only in approved environments.
\nRisk: CAD files may be untrusted inputs and conversion output may not fully render complex hatch boundaries, dimension arrow symbols, or 3D entities.
\nMitigation: Run conversion only on CAD files you trust and review the generated PDF before relying on it for engineering, printing, or sharing workflows.

HATCH填充/尺寸标注/块引用完整渲染\n- ✂️ **自动拆页** - 检测粉紫色图框，每框一页\n- 🔍 **大样图检测** - 自动检测图框外实体聚集区域，独立页面\n- 🈶 **天正MBCS解码** - `\\M+5CDE2` → \"外\"，中文不乱码\n- 📏 **DIMENSION修复** - 标注insert在原点时自动移到实际位置\n- 🔢 **索引圆圈编号补全** - ODA转换丢失的SHX编号自动补绘\n- 🎨 **黑白输出** - 适配打印，不同材质用不同灰度区分\n\n## 依赖安装\n\n### Python依赖\n```bash\npip install ezdxf matplotlib --break-system-packages\n```\n\n### 系统依赖（DWG转DXF才需要）\n```bash\n# ODA File Converter\nwget \"https://www.opendesign.com/guestfiles/get?filename=ODAFileConverter_QT6_lnxX64_8.3dll_27.1.deb\" -O /tmp/ODAFileConverter.deb\nsudo dpkg -i /tmp/ODAFileConverter.deb\nsudo apt-get install -y libxkbcommon-x11-0 libxcb-icccm4 libxcb-image0 libxcb-keysyms1 libxcb-render-util0 libxcb-xkb1\n\n# 中文字体\nsudo apt-get install -y fonts-noto-cjk\n```\n\n## 使用方法\n\n### 基本用法\n```bash\n# DXF转PDF\npython3 scripts/dxf2pdf.py 图纸.dxf 输出.pdf\n\n# 指定纸张和DPI\npython3 scripts/dxf2pdf.py 图纸.dxf 输出.pdf --paper A3 --dpi 300\n\n# DWG文件（自动先转DXF）\nbash cad2pdf.sh 图纸.dwg 输出.pdf\n```\n\n### Shell封装\n```bash\nbash cad2pdf.sh 图纸.dxf # 自动命名输出\nbash cad2pdf.sh 图纸.dxf 输出.pdf --paper A2\n```\n\n### 命令行参数\n- `--paper SIZE` -
