AutoCAD Dynamic Draw — Claude Code Skill

Enterprise-grade AutoCAD dynamic drawing skill for Claude Code & Codex.
Step-by-step COM-driven drafting with real-time visualization. Ideal for design reviews, training demos, process documentation, and on-screen walkthroughs.

Quick Install

npx skills add js2005happy/autocad-dynamic-draw --skill autocad-dynamic-draw

Or via npm:

npm install -g autocad-dynamic-draw

Prerequisites

| Requirement | Version | |-------------|---------| | Windows | 10/11 | | AutoCAD (full, not LT) | 2000+ | | Python | 3.8+ | | pyautocad | latest | | Claude Code / Codex | latest |

pip install pyautocad

Usage

1. Start AutoCAD and open or create a drawing.
2. In Claude Code, use any trigger phrase:

使用 AutoCAD 动态绘制一个 100x100 的正方形，左下角在原点，四角 R10，延时 0.8 秒

Or explicitly:

/autocad-dynamic-draw 画一个法兰盘，外圆 φ200，内孔 φ80，步长 1 秒

Features

• Step-by-step visual drafting — every entity drawn with configurable delay
• Auto layer management — CLAUDE_DRAW layer by default (customizable)
• Auto backup — saves DWG snapshot before each session
• Structured logging — timestamped log of every operation
• Error recovery — graceful failure handling, preserves AutoCAD state
• Safety sandbox — no eval(), exec(), os.system() in generated scripts

Configurable Parameters

| Parameter | Default | Description | |-----------|---------|-------------| | step_delay | 0.8 | Pause between draw steps (seconds) | | backup_before_draw | true | Backup DWG before drawing | | layer_name | CLAUDE_DRAW | Target layer name | | line_weight | 0.25 | Default line weight (mm) | | text_style | Standard | Annotation text style |

Override any parameter inline:

用 AutoCAD 动态绘制法兰，图层用 "FLANGE_V1"，延时 1.5 秒，不备份
