@mlightcad/dxf-json-converter

The dxf-json-converter package provides a DXF file converter for the RealDWG-Web ecosystem, enabling reading and conversion of DXF files into the AutoCAD-like drawing database structure. It is based on @mlightcad/dxf-json.

Overview

This package implements a DXF file converter compatible with the RealDWG-Web data model. It allows you to register DXF file support in your application and convert DXF files into the in-memory drawing database.

DXF parsing is provided through a dedicated Web Worker bundle (dxf-parser-worker.js). This converter is intended for Web Worker use only. That restriction is not because parsing cannot run on the main thread in principle; it is a deliberate licensing choice. @mlightcad/dxf-json is GPL-3.0, and loading it in a separate worker bundle helps keep copyleft parser code apart from the main MIT-licensed application so license obligations are easier to manage.

Key Features

• DXF File Support: Read and convert DXF files to the drawing database
• Worker-based Parsing: Required by design for GPL license isolation
• Integration: Designed to work with the RealDWG-Web data model and converter manager

Installation

npm install @mlightcad/dxf-json-converter

Peer dependencies:

• @mlightcad/data-model

Usage Example

import { AcDbDatabaseConverterManager, AcDbFileType } from '@mlightcad/data-model';
import { AcDbDxfConverter } from '@mlightcad/dxf-json-converter';

const dxfConverter = new AcDbDxfConverter({
  useWorker: true,
  parserWorkerUrl: './assets/dxf-parser-worker.js'
});
AcDbDatabaseConverterManager.instance.register(AcDbFileType.DXF, dxfConverter);

Deploy dxf-parser-worker.js from this package's dist/ folder to a public URL accessible by your application.

API

• AcDbDxfConverter: Main converter class for DXF files (extends AcDbDatabaseConverter)

Dependencies

• @mlightcad/data-model: Drawing database and entity definitions
• @mlightcad/dxf-json: DXF file parser (GPL-3.0), loaded in the worker bundle by design for license isolation
