Viewer Release Notes: v 6.3.*

November 28, 2018


Autodesk.PDF extension

Prototype vector rendering loader for PDF files.

Sample code:

// Create Viewer instance and load PDF file on page 1
    Autodesk.Viewing.Initializer(options, function() {
        var viewer = new Autodesk.Viewing.Viewer3D(div,config3d);
        viewer.loadExtension('Autodesk.PDF').then(function() {
            // URL parameter `page` will override value passed to loadModel
            viewer.loadModel('path/to/file.pdf', { page: 1 });

Autodesk.DocumentBrowser extension

Toolbar button and panel for viewing all 2D and 3D models available in a JSON manifest.

New model loading API: viewer.loadDocumentNode(lmvDocument, bubbleNode, options)


loadOptions.skipHiddenFragments:bool to skip initially hidden meshes
