5.2.3 Polygon
More general is the polygon object, with syntax:
POLYGON:
polygon { NUM_POINTS, POINT, ..., POINT [OBJECT_MODIFIERS] }
See also:
One has to make sure, that the POINTS all ly in one plane. This is easiest
by taking on coordinate constant (say 0) and rotate the polygon afterwards
to the required position.
