Lofted Bend flat pattern

I recently did a rectangular to round transition where theround was not centered on the rectangle (not that that matters).When the shop went to form the parts they decided that they neededmore material in the development. I went into the part file andnoticed this strangeness: No matter what I do to the K-Factor theflat pattern does not change. I tried changing the thickness of theloft and still no change to the flat pattern. So am I correct inassuming that the lofted bend command is disabled in thisregard?SolidworksSheet Metal
