void c_geometry::generate_cylindrical_structure	(	int	itx,
		int	nop
	)

inline

Rotates structure along Z-axis to generate a copies in a cylindrical array.

Parameters

itx	The tag number increment.
nop	The total number of times that the structure is to occur in the cylindrical array.

void c_geometry::geometry_complete	(	nec_context *	in_context,
