Adjust Displaying of Primitives
You can enable and disable the drawing of Surfaces, Lines, Points, Snap
Points, and 3D Text in the Scene View.
Points are “real” points in the model, whereas Snap Points mark locations
on other primitives, for example the center of a circle, and are useful for
snapping to when measuring.
Surfaces
Surfaces are the triangles that make up the 2D and 3D items in the scene. You
can toggle the rendering of surfaces in the model.
