<h1>DistanceMeasurementPlugin with DistanceMeasurementsTouchControl and Pointerlens</h1>
<h2>Touch the model to create distance measurements, with vertex and edge snapping</h2>
<p>In this example, we're loading a BIM model from the file system, then creating distance measurements wherever the
user taps on the model with touch input. Only works with touch devices.</p>
