The sight line is shown shooting vertically downwards outside of the model area.

Are you including a ground model when you do your analysis? The &#39;outside model&#39; message would occur if your sight line crosses the inside of a curve (for example) and there is no information outside the interface strings to check against. Having the ground model included should help.</p><div style="clear:both;"></div>
