■ B<0: Surface in negative Z direction
■ B>0: Surface in positive Z direction
X: Reference diameter
■ No entry: ”X” from section code.
■ ”X” overwrites ”X” from section code.
C: Angular position of the surface normal
■ No entry: ”C” from section code
■ No Entry and ”C” not programmed in the section code:
C=0
Q: Number of sides (Q ‡ 2)
