three-dxf-loader

three-dxf-loader is a cross platform DXF file loader for THREE.js. It takes URL of a DXF file as input and returns THREE.js mesh entities. It internally uses dxf-parser for parsing DXF file. This library works out of the box with cross platform react-native and react-three-fibre.

Install

yarn add three-dxf-loader three

npm i three-dxf-loader three

Usage

import * as THREE from 'three'
import { DXFLoader } from 'three-dxf-loader'

const loader = new DXFLoader();
// loader.setFont(font); // set fonts
const scene = new THREE.Scene();
onLoad = (data) => {
    if (data && data.entities) {
      data.entities.forEach(ent => scene.add(ent))
    }
}
const onError = (error) => {
  console.log(error);
}
const onProgress = (xhr) => {
  console.log( ( xhr.loaded / xhr.total * 100 ) + '% loaded' );
}
loader.load(url, onLoad, onProgress, onError);

After performing the steps above, you can see the example at http://127.0.0.1:8080/sample/index.html. You can use the DXF file included in the sample. NOTE: the latest version of http-server will go into a redirect loop if you exclude "/index.html" from the url.
