I have a 3D point outside a building as shown in the figure. I utilized the Construct Sight Lines tool to generate lines between the point and points which represent the vertices of the building.

Now, on running the Intervisibility tool with the building (multipatch) as an obstruction, all the lines are assigned a value of 1 as shown in the figure, which means the end and start points are visible.

The obstruction is not considered.

  • When you used the Intervisibility tool what parameter values did you use?
