About Twist Walls
You can use the Twist Wall tab to create a spiral or coil-shaped section of sheet metal. The twist forms around an axis running through the wall's center, as if by turning the wall ends in opposite directions by a relatively small, specified angle. You can attach the twist to a straight edge on an existing planar wall.
The twist wall typically serves as a transition between two areas of sheet metal because it can change the plane of a sheet metal part. The twist can be rectangular or trapezoidal.
 
You can only add a flat or extruded wall to the end of a twist if the additional wall has no radius and is tangent to the twist.
You can unbend a twist wall with the regular unbend command.
The twist axis runs through the wall's center, perpendicular to the attach edge.
You cannot use a radius with twist walls.
