When we make lofted flanges in the shop for square to round applications, they prefer the parts to be cut at the corners (so a square to round lofted flange cut at all four corners - bent then welded)
Please give us an option to cut at the corners without having to do the not great adjustment of closing the gap size and changing the bend radius then ripping. This fails so often, the corner should be able to be adjusted similar to how flange edges are, overlap etc)
