X axis of C (nf block) > X axis of B (ns block); Z axis of C > Z axis of B  ① 
X axis of C (nf block) > X axis of B (ns block); Z axis of C < Z axis of B  ② 
X axis of C (nf block) < X axis of B (ns block); Z axis of C > Z axis of B  ③ 
X axis of C (nf block) < X axis of B (ns block); Z axis of C < Z axis of B  ④ 
X axis of C (nf block) = X axis of B (ns block) or 
Z axis of C (nf block) = Z axis of B (ns block)
