CREATE COSINE ANGLES FROM DIFFERENT COORDINATES¶
Computes the direction cosine angles for a local coordinate system defined by three 3-D points: an origin, a point on the Y-plane, and a point on the Z-plane. Use this worker whenever you need to convert explicit coordinate triples into the cosine-angle representation required by LS-DYNA or similar solvers for local coordinate frame definitions.
