CADGuide Tools (cadguide-tools)

Open-source CAD & BIM format specifications, DWG header version signatures, and sheet metal engineering calculators toolkit.

Powered by CADGuide.tools — The authoritative free reference platform for CAD/BIM engineers, architects, and industrial designers.

🌟 Features

• DWG Header Version Matrix: Quick mapping between internal binary signatures (AC1032, AC1027, AC1024, etc.) and consumer release years (AutoCAD 2000 to 2025).
• Sheet Metal K-Factor Utilities: Accurate bend allowance calculation based on neutral axis shift, sheet thickness, and internal bend radius.
• Fast Buffer Detection: Lightweight magic byte inspection for DWG, DXF, and STEP AP203/AP214/AP242 files.
• TypeScript Support: Full type definitions included out of the box.

📦 Installation

npm install cadguide-tools

or via Yarn / pnpm:

yarn add cadguide-tools
pnpm add cadguide-tools

🚀 Quick Usage

1. DWG Version Compatibility Lookup

const { DWG_VERSIONS, detectCadFormat } = require('cadguide-tools');

// Look up specs for AutoCAD 2018 - 2025 DWG signature
console.log(DWG_VERSIONS['AC1032']);
// Output: { version: 'AutoCAD 2018 - 2025', year: 2018, readCompatible: [...] }

2. Sheet Metal Bend Allowance Calculation

const { calculateBendAllowance } = require('cadguide-tools');

// 90 degree bend, 2mm sheet thickness, 3mm inner radius, 0.40 K-Factor
const ba = calculateBendAllowance(90, 2.0, 3.0, 0.40);
console.log(`Bend Allowance: ${ba.toFixed(3)} mm`);
