An improved manufacturing method includes virtually aligning scanned virtual vane components that are virtual electronic counterparts of separately manufactured and three-dimensionally scanned physical vane components used in gas turbine engines. The improved method performs virtual alignments for any of various possible virtual combinations of the virtual vane components to predict how their physical counterparts would likely behave in combination with each other before those physical counterparts are inseparably combined. One or more optimal virtual combinations are identified, in turn indicating optimal physical combinations to select to form physical vanes incorporated into one or more gas turbine engines, in turn improving the quality of the vanes and ultimately engine performance.
