 #### User Aligned Cube
 
 A user aligned cube volume is a rectangular shape that rotates to align with the users local coordinate system.
 
 ### Observation Extents
 
-The observation extents define the distance from the observation point that meshes will be observed. When the [Observer Shape](#observer-shape) is set to Sphere, the X value of the extents will be used as the radius of the sphere.
