cadguide-cli

Zero-upload, client-side AutoCAD DWG binary header inspector, sheet metal K-factor calculator, and engineering toolbox.

Developed by the CADGuide.tools engineering team.

⚡ Key Features

• 🔍 Instant DWG Version Check: Read the first 6 bytes of binary header in < 3ms without uploading confidential IP to third-party servers.
• 📐 Sheet Metal K-Factor Calculator: Calculate Bend Allowance ($BA$) and Bend Deduction ($BD$) for precision air bending and bottoming dies.
• 🧭 Cross-CAD Shortcut Matcher: Quick lookup for AutoCAD, GstarCAD, ZWCAD, BricsCAD, FreeCAD, and Rhino command mappings.
• 🛡️ 100% Private & Offline: Operates purely on local file streams without telemetry or cloud uploads.

📦 Installation & Usage

Use via npx (No installation needed)

# Inspect a local DWG drawing
npx cadguide-cli dwg ./drawing.dwg

# Calculate sheet metal K-Factor
npx cadguide-cli kfactor 2.0 2.0 90 0.44

Global Installation

npm install -g cadguide-cli

# Run anywhere
cadguide dwg ./sample.dwg
cadguide kfactor 3.0 3.0

💻 Programmatic Node.js API

const { parseDWGHeader, calculateKFactor } = require('cadguide-cli');
const fs = require('fs');

// 1. Inspect DWG buffer (only first 6 bytes required)
const buffer = fs.readFileSync('sample.dwg');
const header = parseDWGHeader(buffer);
console.log(header.releases); // e.g. "AutoCAD 2018 - 2026"

// 2. Sheet metal calculation
const result = calculateKFactor(2.0, 2.0, 90, 0.44);
console.log(`Bend Allowance: ${result.bendAllowance} mm`);
