JavaScript API

On your page

Reference the following JavaScript Libraries:

<link rel="stylesheet" href="https://viewing.api.autodesk.com/viewingservice/v1/viewers/style.css" type="text/css">
<script src="https://viewing.api.autodesk.com/viewingservice/v1/viewers/viewer3D.min.js"></script>

Put the viewer on your page

Create a div with id "viewer"

<div id="viewer"></div>

Initialize with JavaScript

function initialize() {
    var options = {
        'document' : 'urn:dXJuOmFkc2sub2JqZWN0czpvcy5vYmplY3Q6bXlidWNrZXQvc2t5c2NwcjEuM2Rz',
        'env':'AutodeskProduction',
        'getAccessToken': getToken,
        'refreshToken': getToken,
        };
    var viewerElement = document.getElementById('viewer');
    var viewer = new Autodesk.Viewing.Viewer3D(viewerElement, {});

    Autodesk.Viewing.Initializer(options,function() {
        viewer.initialize();
        loadDocument(viewer, options.document);
    });
}

loadDocument

function loadDocument(viewer, documentId) {
    // Find the first 3d geometry and load that.
    Autodesk.Viewing.Document.load(documentId, function(doc) {
    var geometryItems = [];
    geometryItems = Autodesk.Viewing.Document.getSubItemsWithProperties(doc.getRootItem(), {
        'type' : 'geometry',
        'role' : '3d'
    }, true);

    if (geometryItems.length > 0) {
        viewer.load(doc.getViewablePath(geometryItems[0]));
    }
 }, function(errorMsg) {// onErrorCallback
    alert("Load Error: " + errorMsg);
    });
}

token

function getToken() {
        return "GX6OONHlQ9qoVaCSmBqJvqPFUT5i";
}
