This document defines the geometry of a 90 degree ductile iron elbow fitting for an 8 inch pipe using lines, rectangles, and arcs. It includes the horizontal and vertical pipe centerlines, right and left flanges, and the pipe inner and outer edges. The fitting is created using the Fitting Definition Language to define ductile iron fittings for pipe sizes ranging from 8 to 48 inches.
