Usage no npm install needed!

Three-Dxf is a javascript viewer for dxf files. It takes dxf objects produced from Dxf-Parser and renders them using three.js.


npm install three-dxf

For now we recommend cloning the repo, and starting with our sample. See Run Samples below.

Example of the viewer


// See index.js in the sample for more details
var parser = new window.DxfParser();
var dxf = parser.parseSync(fileReader.result);
cadCanvas = new ThreeDxf.Viewer(dxf, document.getElementById('cad-view'), 400, 400);

Run Samples

# first, compile three-dxf
> npm install
> npm run build

# then install the sample's dependencies
> cd sample
> npm install

# go back to the root and run http-server to run the sample
> cd ..
> npm install -g http-server@0.9.0
> http-server .
# use `http-server -c-1 .` to prevent caching

After performing the steps above, you can see the example at 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 exlcude "/index.html" from the url.
