Point.
No height, width or depth. (H, W, D=3D)
Point = point
Point under simplest Thomistic change/"motion", namely single vector time/space (4D) =
Line
Length, no width, nor depth. Under second vector (5D) =

Wiggle a pencil to get an idea of "line".None of the above are "real", but that doesn't mean that they do not exist.
No abstraction exists of itself. No one can show anyone "blue" or a numeric quantity for example.Geometric solids likewise do not exist sans certain abstract qualities such as lines.
