Hi Tom, Thanks for catching that ! You're right that there are no interesctions. But my surface is not a NULL and my x, y coordinates are also valid numbers as I check with console output statements.
I found the reason for this behavior. I was using a stream of coordinates data and these ccordinates are not always over the terrain surface I was using. And in those cases that the coordinates were "off" my surface, I just gave a default value if 0 to elev and in cases where the coordinates lie over my surface, the intersector finds intersections and places the model correctly over my terrain surface. Thanks for the tips...
