Structural Annulus (SANN)

SANN has particular attributes as follows:

• PX, PY—coordinates of centre of annulus.

• DX, DY—offset of coordinates of centre of annulus between ends of section.

• PRAD—external radius.

• DRAD—change of external radius between ends of section.

• PWID—width of annulus.

• DWID—change of width between ends of section.

• PANG—angle subtended by annulus.

• PLAXI—start angle.

  Note: PANG must be in the range -180_ to +180_. Positive angles are anticlockwise when the primitive is viewed in the -Z direction.
