forgive me if this has been answered before, im having a brain fart. basically i have two sets of points which i drew curves through then lofted. from that surface i want to get the exact midline of the surface. i attached my definition and an image. in the actual definition i used sin graphs for the points before i lofted so the midline would need to be an average of those curves. any help is much appreciated, thanks guys and gals.
