In SketchUp, a point cloud is a collection of millions of tiny points in 3D space that represent the shape and surface of a real-world object, building, or environment.
Each point has X, Y, and Z coordinates, and sometimes color (RGB) or intensity data. Together, these points form a “cloud” that looks like a 3D model — though it’s actually just data points, not solid geometry.
I do not have that version of SU but I assume View/toolbars turn off point cloud by unchecking the box
