CAD Editor Skill\r
\r 将自然语言指令转换为工程图纸（DXF + PNG/SVG/PDF）。覆盖建筑、机械、电气、管道、结构五大领域，\r 遵循 GB/T 制图标准。\r \r
触发条件\r
\r 当用户要求绘制 CAD 图纸、工程图、施工图、配筋图，或提及以下任一领域时使用本技能：\r
- 建筑图纸：平面图、立面图、剖面图、门窗、楼梯、墙体、梁板柱基础\r
- 机械图纸：螺栓、齿轮、轴承、弹簧、垫圈、螺母、销钉、键槽\r
- 电气图纸：开关、插座、灯具、配电箱、断路器、导线组\r
- 管道图纸：直管、弯头、三通、法兰、阀门、大小头、管帽\r
- 结构详图：梁断面、楼板配筋、条形基础、独立基础\r
- 通用几何：线、圆、弧、矩形、多边形、尺寸标注\r \r
工作流\r
\r
步骤 1：解析自然语言指令\r
\r 调用 NL 解析器识别意图并提取参数：\r \r
import sys\r
sys.path.insert(0, 'cad-editor/scripts')\r
\r
from nl_parser.intent_classifier import IntentClassifier\r
from nl_parser.param_extractor import ParamExtractor\r
\r
classifier = IntentClassifier()\r
intent = classifier.classify(user_input) # → intent_dict\r
extractor = ParamExtractor(intent['domain'])\r
params = extractor.extract(user_input) # → param_dict\r
```\r
\r
`references/intent_templates.json` 包含 52 条预定义意图映射模板，涵盖 6 大类图纸。\r
\r
### 步骤 2：生成绘图脚本\r
\r
根据意图类型调用脚本生成器：\r
\r
```python\r
from nl_parser.script_generator import ScriptGenerator\r
\r
gen = ScriptGenerator()\r
script_code = gen.generate(intent, params) # → Python str\r
```\r
\r
生成器内置 18 套脚本模板，按领域分：\r
| 领域 | 模板数 | 覆盖组件 |\r
|---|---|---|\r
| architectural | 5 | 墙/门/窗/柱/楼梯 |\r
| mechanical | 4 | 螺栓/齿轮/轴承/弹簧 |\r
| electrical | 3 | 开关/插座/灯具/导线组 |\r
| piping | 3 | 直管/弯头/三通/阀门 |\r
| structural | 3 | 梁断面/楼板/基础 |\r
\r
### 步骤 3：执行脚本生成 DXF\r
\r
```python\r
# 将 script_code 写入临时文件后执行，或直接 exec\r
exec(script_code)\r
# 输出：{output_dir}/{name}.dxf\r
```\r
\r
### 步骤 4：渲染预览图片\r
\r
```python\r
from core.renderer import Renderer\r
Renderer.render_quick(doc, output_dir='output', name='drawing_name')\r
# 输出：{output_dir}/drawing_name.png (自动生成)\r
```\r
\r
### 步骤 5：交付结果\r
\r
向用户展示 PNG 预览图，同时提供 DXF 文件路径。\r
\r
## 直接 API 调用方式（跳过 NL 解析）\r
\r
当需要精确控制或编程调用时，直接使用 Python API：\r
\r
```python\r
import sys\r
sys.path.insert(0, 'cad-editor/scripts')\r
\r
from core.document import CADDocument\r
from core.renderer import Renderer\r
from layer.manager import LayerManager\r
from layer.linetypes import Linetypes\r
from entities import *\r
from templates.architectural import ArchitecturalTemplates\r
from dimension import LinearDimension\r
from layout.paperspace import PaperSpace\r
\r
doc = CADDocument.new(version='R2010')\r
msp = doc.modelspace()\r
\r
Linetypes.load_standard(doc)\r
LayerManager(doc).setup_template('arch')\r
\r
ArchitecturalTemplates.wall(msp, [(0,0), (5000,0), (5000,3500), (0,3500)], thickness=240)\r
ArchitecturalTemplates.door_single(msp, (2500, 0), width=900)\r
ArchitecturalTemplates.window(msp, (800, 240), (2000, 240))\r
LinearDimension.chain_horizontal(msp, [(0,-600),(0,0),(5000,0),(5000,-600)], offset=800)\r
PaperSpace.draw_title_block(msp, (0,0), size='A3', title='图纸标题')\r
\r
CADDocument.save(doc, 'output/drawing.dxf')\r
Renderer.render_quick(doc, output_dir='output', name='drawing')\r
```\r

Usage Guidance
This package appears to be a legitimate CAD generator, but take these precautions before running it: (1) Review the script_generator and any template files (script_generator.py, intent_classifier.py, param_extractor.py) to ensure generated code is what you expect — the runtime uses exec(script_code) which can run arbitrary Python. (2) Run the skill in an isolated environment (container or sandbox) with limited filesystem access if possible, because it writes DXF/preview files to disk. (3) Ensure dependencies (ezdxf, matplotlib, numpy) are installed from trusted package indexes. (4) If you plan to use on sensitive hosts, search the remaining omitted files for any network calls or subprocess usage; if none exist, the blast radius is limited to local file I/O. If you want higher assurance, provide the full script_generator.py and any remaining files for review or run the skill first on non-production data/machine.
Capability Analysis
Type: OpenClaw Skill
Name: cad-editor
Version: 1.0.0
The CAD Editor skill bundle implements a workflow where natural language is converted into Python scripts that are subsequently executed to generate DXF and image files. A significant security risk is identified in SKILL.md, which explicitly instructs the AI agent to use 'exec(script_code)' to run generated logic, creating a high potential for Remote Code Execution (RCE) if the input is not strictly sandboxed. While the underlying Python modules (e.g., scripts/nl_parser/script_generator.py and scripts/core/renderer.py) appear to be legitimate CAD utilities using ezdxf and matplotlib, the architectural choice to execute dynamically generated code based on user prompts is a major vulnerability.
Capability Tags
Capability Assessment
Purpose & Capability
Name/description (natural-language → DXF/PNG/SVG/PDF CAD generation) matches the shipped Python modules (NL parser, script generator, templates, renderer) and the declared Python dependencies (ezdxf, matplotlib, numpy). The provided templates and entity tool modules align with the stated CAD domains (architectural, mechanical, electrical, piping, structural).
Instruction Scope
Runtime instructions explicitly tell the agent to generate Python source (script_code) and run it via exec(script_code) or write+execute a temp file. Executing generated Python gives the skill broad ability to perform file I/O and arbitrary computation within the agent environment; this is functionally required for a code-generation-based CAD skill but increases runtime risk. The SKILL.md references only local files (intent_templates.json, scripts/*) and rendering output; there are no instructions to contact external endpoints or read unrelated system config or environment variables.
Install Mechanism
No install spec is present (skill metadata lists it as instruction-only), yet the package includes ~50 Python files that will be imported/executed at runtime. Dependencies are listed as pip packages (ezdxf, matplotlib, numpy) but no automated installer is provided. This is coherent but means the agent/runtime must already have or install these packages; lack of an install step may cause runtime attempts to pip-install or fail. No downloaded remote archives or external installers were observed in the files reviewed.
Credentials
The skill requires no environment variables, no credentials, and does not request access to unrelated config paths. That is proportionate to a local CAD generator which operates on provided inputs and writes DXF/preview files.
Persistence & Privilege
always is false and the skill does not request elevated platform privileges. It writes output files (DXF/PNG/SVG/PDF) to local paths as expected for its purpose; no evidence that it modifies other skills or agent-wide settings.
How to Use
- Make sure OpenClaw is installed (local or Docker)
