Based on the theory of wide electron beam focusing with curved axis, a method for determining the off-axis point spread distribution is studied using the trajectories with curved axis.

The curved wall separates the car port from the exterior steps leading to the main entrance landing, strengthening the central axis shift to the west and producing a subtle but noticeable asymmetry.

In the forming technique of cylindrical spiral curved surfaces, the contour of workpiece is virtually the result that disk shaped milling tools feed into the workpiece and move around its axis.
