Treat a rolling offset as two moves happening at once. Find the true compound offset first, then use the 45° travel multiplier if you are using 45° fittings.
['A rolling offset is not just a side shift or a drop. It moves in two directions at the same time, so the true offset is the diagonal between those two measurements.', 'Square both field shifts, add them, take the square root, then apply the fitting multiplier for the elbow angle being used. Rotate the adjustable elbows to match the compound path before locking and sealing.']
