2D
Every figure here is computed in the page from its definition, not drawn by hand. The 600-cell's 120 vertices are generated from the φ coordinates, its 720 edges found by distance, its 12 decagonal rings built as cosets of an order-10 quaternion subgroup, and its 30-fold shadow taken on the H4 Coxeter plane. Rotate anything; the relationships hold because they are the construction, not a rendering of one.
The five-divisioned grid follows the drawing procedure in the source framework's chapter on communication: circle, equal divisions, radii extended past the rim, a circle at each division point, then every point joined to every other point.
Take the 600-cell further: rotate it with the 120-cell, merge the two as one dual pair, flatten both into their thirty-fold shadows, and read every rod length needed to build them.
