<ul>
<li>Place a marker in the 3D scene near the feature of interest. Drag the marker closer if needed.<br/>This will set the 3D model distance.</li>
<li>Drag the corresponding marker over the map to what looks like the feature of interest to set the map distance.<br/>If the <b>show marker info</b> is enabled the distances and the difference will be displayed.</li>
</ul>
Update measurements:
<ul>
<li>Map distance - drag marker over map</li>
<li>3D model distance - drag marker over 3D scene</li>
