title: How to activate Autodesk Forge Snapper?
body: <p>I'm trying to activate the new Snapper extension implemented since version 7.3 of the viewer.</p>
  
  <p>So I load the extension like that :</p>
  
  <p><code>viewer.loadExtension('Autodesk.Snapping')</code></p>
  
  <p>Seems to work.
  And after, I tried to access described methods like that but I always got this error " getSnapResult is not a function" :</p>
  
  <pre><code>viewer.loadExtension('Autodesk.Snapping').then(extension =&gt;{
      snapper = extension;
  });
  
  snapper.getSnapResult();
  </code></pre>
  
  <p>I'm still using the old extension made by Philippe Leefsma a few years ago :

  <p>But as it's not working anymore in version up to 7.3, I would like to replace with the new one.</p>
