A simple JavaScript interface to DXF written in TypeScript.

DXF (🧩 Still under development 👨🏽‍💻)

🌟 A simple JavaScript interface to DXF written in TypeScript.

✔️ DXF is a JavaScript library, for Nodejs and Browser, it's for creating DXF files in a simple way.

✨ influenced by 🔗 js-dxf.

• 🔥 Now it's supporting AC1021 and above.
• 🔥 Creating minimal dxf content possible.
• 🔥 Tested on 🔗 AutoCAD, 🔗 LibreCAD and 🔗 DWG FastView on mobile.

🗳️ Install the package

yarn add @tarikjabiri/dxf
# Or npm
npm i @tarikjabiri/dxf

⌨️ Code example

import DXFWriter from '@tarikjabiri/dxf';

const dxf = new DXFWriter();
dxf.setTrueColor(200, 0, 207); // Set the true color.
dxf.addLine(0, 0, 100, 100);
let points = [
    [-300, 0, 0],
    [0, 200, 0],
    [300, 70, 0],
    [700, 100, 0],
    [1000, 1200, 0],
];
dxf.unsetTrueColor(); // Unset the true color.
dxf.addLineType('DOT', '. . . . . . . . . . . . . . . . . .', [0, -4])
    .addLineType(
        'ACAD_ISO11W100',
        '__ __ . __ __ . __ __ .',
        [4, -2, 4, -2, 0, -2]
    )
    .addLineType('DOT2', '.................................', [0, -2])
    .addLineType('DASHED', '_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _', [4, -4]);

dxf.addLayer('l_red', DXFWriter.colors.Red, 'DASHED')
    .addLayer('l_green', DXFWriter.colors.Green, 'CONTINUOUS')
    .addLayer('l_cyan', DXFWriter.colors.Cyan, 'CONTINUOUS')
    .addLayer('l_yellow', DXFWriter.colors.Yellow, 'ACAD_ISO11W100');

dxf.setCurrentLayer('l_green')
    .addSpline(points, points, 3, 8, [], [])
    .setCurrentLayer('l_red')
    .addCircle(60, 150, 50)
    .addRectangle(20, 20, 100, 100)
    .setCurrentLayer('l_cyan')
    .addText(30, 30, 10, 'Hello World')
    .addPolyline3D(
        [
            [70, 70, 50],
            [150, 70, 0],
            [170, 170, 150],
        ],
        0
    )
    .addArc(0, 0, 120, 90, 180)
    .addPoint(65, -30, 0)
    .setCurrentLayer('l_yellow')
    .addEllipse(100, 50, 150, 0, 1, 0, 2 * Math.PI)
    .add3DFace(0, 0, 10, 20, 0, 10, 20, -20, 20, 0, -20, 20);
// ✔️ To get the dxf string just call the stringify() method
const dxfString = dxf.stringify();
