METHOD FOR DRAWING BELLMOUTH BY USING 3-DIMENSIONAL MEASUREMENT OF BELLMOUTH MODEL

摘要

A bellmouth drawing method includes dividing a scaled-down bellmouth model from the real bellmouth into a plurality of cross-sections, indicating the cross-sections on a scaled-down bellmouth model with curved lines, measuring coordinates of the curved lines, forming cross-sections of the bellmouth model with the measured coordinates, and creating the drawing of the real bellmouth by scaling-up the cross-sectional views.
