CORD1R – Rectangular Coordinate System Definition, Form 1
Defines a rectangular coordinate system by reference to three grid points. The first point is the origin, the second lies on the z-axis, and the third lies on the x-z plane.

CORD1R definition.
Coordinate system identification numbers on all CORD1R, CORD1C, CORD1S, CORD2R, CORD2C, and CORD2S entries must all be unique.
The three points G1, G2, G3 must be noncollinear. Noncollinearity is checked by the geometry processor.
The location of a grid point (P in the sketch) in this coordinate system is given by (X, Y, Z).
The displacement coordinate directions at P are shown above by (ux, uy, uz).
One or two coordinate systems may be defined on a single entry.
