@willsunagency/dxf-layer-extractor

High-performance, zero-dependency streaming AutoCAD DXF entity and layer extraction engine built for client-side web applications and serverless microservices.

Part of the open engineering tooling suite by CADGuide.tools.

Key Features

• Zero-Cloud & 100% Client-Side Safe: Parse multi-megabyte CAD blueprints directly in browser memory without sending confidential CAD files to remote servers.
• Micro-Footprint: Zero external dependencies; under 3KB minified.
• Section Parsing: Extracts all layers defined in group code 8 and entity records from the ENTITIES section.
• Cross-Platform Compatibility: Works with AutoCAD (Release 12 to 2026), LibreCAD, FreeCAD, BricsCAD, and DraftSight exports.

Installation

npm install @willsunagency/dxf-layer-extractor

Usage

const fs = require('fs');
const { parseDxfLayers } = require('@willsunagency/dxf-layer-extractor');

const dxfString = fs.readFileSync('sample_floorplan.dxf', 'utf-8');
const result = parseDxfLayers(dxfString);

console.log('Detected Layers:', result.layers);
console.log('Total Processed Entities:', result.entityCount);
