    In general, because the materials are too brittle to ensure that the edges are perfectly sharp, the point has no physical representation on mechanical parts.

    However, it often appears as a fictitious element in geometric objects (such as the center of a sphere or the apex of a cone).

    Example

    Examples: the apex of a cone (see figure 1 ), the intersection of the three planes of the faces of a rectangular prism, the center of a circle or a sphere (see figure 1 ).
