Fig.3-83 Area design
Vertical design
—This is similar to the channel design, and the difference is that the width of
channel design is same on the left and right, and the corners were processed. Vertical design is
simpler that it draws the vertical parallel lines only according to the specific baseline and the
spacing, and the width of left and right can be different. It is suitable to the project plan line
design which only knows one side coordinates.
