As fixed and mobile artifacts have displayed geometric capability in fusing one to the other, both find harmonious setting on terra firma as the simple cuboda possesses still more major unused features.

For purposes of topographic design, the geocentric cuboda's key relevant features are depicted from the orientation facing an equatorial vertex. Focus is first on the skewed squares, each alike in having opposing corners converging on both a pole and the equator.

Following primary rotation, a skewed square is positioned latitudinally via secondary rotation about an axis through opposing equatorial squares. Once positioned, the skewed square defines an alternative diamond grid aligned southwest-to-northeast and southeast-to-northwest.

The diamond grid may be integrated into the Polar-Rotational grid by following a simple rule derived from the relationship between the celestial cube and the earth-centered cuboda. From its center, a path is traced outward along an innate radial line to a cube corner.

From there, the path turns to follow the cube’s edge to its outermost corner. The angle between these path lines is 135˚ - the angle specified to be the angle of turn between grids. Om other words, sharp 45° turns are not allowed between grids, a rule that may give the game of baseball some added new meaning. Within each grid, turn angles are 90˚.

  

Another key element of the earth-centered cuboda is represented by any of the 8 vertices that are neither polar or equatorial, that is participating in either primary or secondary rotation of the celestial co-cube.

These remaining vertices are relatively indistinguishable in their occupation of equatorial square corners; and as each vertex represents the convergence of polar and equatorial triangles and squares, the 8 vertices are termed mundane poles.

How the features identified here are imbued with 3-dimensionality, and what this will mean for topographic design is explained in Ground Waves, topic 2 of Ground Rules.
