The 2D expression of transporter/shelter commonality resolving planar Planar Discord proceeds to 3 actual architectural accommodation schemes culminating in a full 3D fusion.

All 3 schemes require the macrocosmic wheel to be employed - represented by its microcosmic version in profile following primary rotation, and secondary rotation to the orientation depicted. In the 1st scheme, secondary rotation of the wheel would proceed another 30˚ such that the accented square's outer leading edge is oriented perpendicular to the ground.

Imagining this square from a ground perspective, it angles back from the leading edge so as to pose a √(2/3) proportioned rectangle. Used in integral numbers, this ratio thus guides design of transporter slots on polar facing walls.

A 2nd scheme involving 3 dimensions requires the wheel to be rotated 90˚ more such that the square's leading edge is oriented horizontally. So oriented, the square slopes at about 35˚ to guide roof design on annexations to east or west (co-cube projected) walls.

A full 3D fusion involves matched triangles of the hexagonally-shifted wheel, oriented as depicted with the edge connecting of the triangular "wings" horizontal before the house roof sloping at angle (Θ).

The (isolated) wings are directed to the roof where their spread angle (ɸ) is adjusted according to the fusion formula to maintain the edge in a horizontal orientation. The resulting overhang is clipped flush to the wall to form a cross gable wheel port that gives the prime celestial projection a polar-facing expression.

This last scheme constitutes full integration in the sense of both roof and wall being involved with the wheel's fusion. Next, fusion formula variability leads to Universal Linking, topic 3 of Polytechnic Integration.
