Analysis objects are blocked by symbols

Hi,

I've noticed that LocationLineOfSight and Viewshed are blocked by symbols that I place on the map.

Is there a way to prevent that??

In my application I have a weapon system with LineOfSight and Viewshed, and many target symbols on the map around it. I have to know which of the targets is within the LOS\Viewshed but they can't affect it (actual targets are very small comparing to their symbols...).

Thanks

Are they 3D symbols that are blocking analysis?

Yes. Tried it with a SimpleMarkerSceneSymbol::cylinder.

All graphics and layers in a scene are currently included in the viewshed/line of sight analyses. We are looking into adding ways to exclude certain elements from the analysis for a future release.
