Full Vertical Surface Enrichment
(C) Zone of Enrichment: full surface enrichment in a horizontal position.
Type of Design: A symmetrical pattern generally radiating from the geometric center of the surface and covering at least two-thirds of the surface.
Inceptive Axes: Diameters or diagonals of the area.
Points of Concentration: At the corners or the center of the outer margin; at geometric center, as in a rosette.
Illustrations: [Figures 283], [289], and [291].
Full Horizontal Surface Enrichment
(D) Zone of Enrichment: full surface enrichment in a vertical position.
Type of Design: A symmetrical pattern with a strong upward movement and covering more than one-half of the surface.
Inceptive Axis: The vertical center line.
Point of Concentration: Upper section of the surface.
Illustrations: [Figures 290] and [292].
