Interface to Alias arc curve attributes.
#include <AlRevSurfAttributes.h> class AlRevSurfAttributes : public AlAttributes virtual AlObjectType type() const; AlObject* copyWrapper() const; double startAngle() const; double endAngle() const;
AlRevSurfAttributes is a class derived from the AlAttributes class. This class allows access to some of the attributes of a revolved surface; in this case, the start and end angles of revolution.
When querying the attributes of a revolved surface (retrieved from IGES or created in Alias with exact ON) the first attribute will be an AlRevSurfAttributes, the second will be an AlLineAttributes representing the axis of revolution, and the remainder of the attributes describe the line that was revolved to generate the surface.
