A Human Design cross entry records one of the Incarnation Crosses of the Human Design system, Ra Uru Hu's own founding presentation of which sets out each cross as built from two pairs of I Ching gates positioned at the four fixed angles of a birth chart, one pair from the conscious personality placement and one from the unconscious design placement, read together as describing a life's overall theme or fixed direction rather than any single trait.
An entry records a cross's family, Right Angle, Left Angle or Juxtaposition, its four constituent gates and the theme practitioners within the system assign to that specific combination, following the vocabulary and structure Ra Uru Hu's own text lays out for how the crosses are built and named.
The three families are read as varying how much a life is shaped by circumstance beyond one's choosing against how much room the system holds for individual decision, Right Angle crosses read as most shaped by circumstance, Juxtaposition crosses as most self directed, and an entry states this as the system's own internal claim about itself, a practitioner's account of a system its founder built by combining older sources into a construction of his own, rather than as an independently verified psychological finding.
