I am trying to make a sheetmetal part that has a series of cutouts. Each cutout has an edge flange on either side of the extruded cut. I am able to do a linear pattern of the cutout but I can't pattern the edge flanges. Is this even possible? It just seems like there should be a better way of making my required flanges without having to go through and make each flange a separate feature. The file is attached.
