Points are real points in the model, for example, the points in a point cloud in a laser scan file. You can toggle the rendering of points in the model. You can also change the size of drawn points by using the Options Editor.
Click the application button > Options.
In the Options Editor > Interface node, click the Display option.
On the Display page > Primitives area, enter a number between 1 and 9 in the Point Size box.
This sets the size in pixels for points drawn in the Scene View.
Click OK.
