A method is provided during which surface data indicative of a measured surface geometry of a component (30) is received. The surface data is processed to provide model data indicative of a solid model of the component. The model data is processed to determine a center of gravity distance of the component. A moment weight of the component is determined based on the center of gravity distance of the component and a measured weight of the component. The moment weight is communicated with the component. In a manufacturing method, model data indicative of a solid model of a rotor blade is received ; a center of gravity distance of the rotor blade is determined using the model data; a moment weight of the rotor blade is determined based on the center of gravity distance of the rotor blade and a measured weight of the rotor blade; a location for the rotor blade to be connected to a rotor hub based on the moment weight is determined ; and the rotor blade is connected to the rotor hub at the location. In a n inspection method a weight of a rotor blade is determined; a surface geometry of the rotor blade is measured using a surface inspection system (18); model data is generated ; a center of gravity distance of the rotor blade is determined ; a moment weight of the rotor blade is determined; and the moment weight is communicated with the rotor blade.
