title: How to create MapElement3D from a 3mf file?
body: <p>I am trying to create a UWP MapElement3D object from a 3mf file inside the Assets folder of my Visual Studio Project. However, I keep getting this error: </p>
  
  <blockquote>
    <p>Failed to create MapModel3D from 3MF stream.</p>
  </blockquote>
  
  <p>This is where my code crashes:</p>
  
  <pre><code>RandomAccessStreamReference reference = RandomAccessStreamReference.CreateFromUri(new Uri("ms-appx:///Assets/Crane.3mf"));
  var myModel = await MapModel3D.CreateFrom3MFAsync(reference, MapModel3DShadingOption.Smooth);
  </code></pre>
  
  <p>My goal is to render that 3D model into a MapControl component.</p>
  
  <p>Any ideas on how to solve this?</p>
