16、,nthe horizontal line that defines the xaxis for the pattern piece.DISCUSSIONThe position of all other graded lines and points on thepiece are determined in reference to grade reference line(s).A piecemust have a grade reference line and may have one or more alternategrade reference lines.(See alternate grade reference line.)grade rule,na named set of grade rule values consisting ofone grade rule value for each size in the size line.(See graderule values.)DISCUSSIONA grade rule is named by the g
