##Description

A collection of various JavaScript extensions for the viewer, showing what is doable with the client-side JavaScript API.

##Dependencies

Some extensions are dependent on specific files which are placed in the same directory. Dependencies need to be loaded before loading the extension, using a simple <script> tag in your html or dynamically using require or equivalent. The path of dependencies needs to be modified accordingly to your setup.

##Setup/Usage Instructions

There are two ways to load an extension with viewer API:

• Load extensions when viewer is initialized:

    var viewerElement = document.getElementById('viewer');
  
    viewer = new Autodesk.Viewing.Private.GuiViewer3D(viewerElement, {
        extensions: ['BasicExtension']
    });
    
  
    Autodesk.Viewing.Initializer(options, function () {
        viewer.start();
        loadDocument(viewer, options.document);
    });
  

Please refer to this sample for detail.

• Load extensions dynamically on demand:

    //load extension for SEO
    viewer.loadExtension('Autodesk.ADN.Viewing.Extension.SEO');
