Make a CAD assembly drawing in 3rd angle projection. Drawing must be in scale.

The figure on the other side of the paper shows the front view, section and the detailed view of the passenger cabin window on a Concorde airplane.   1. Make a CAD assembly drawing in 3rd angle projection. Drawing must be in scale. Required dimensions should be obtained by measurements and reengineering the drawing on the next page. In the drawing indicate following design features: a. Which of the two window panels normally carries the internal cabin pressure load? b. Which window panel acts as a heat shield?  c. Identify 4 rubber seals in the design. Which seals serve to maintain cabin pressure? d. Why flat glass is used? e. Why the window is relatively small in area? f. By what means the window is prevented from misting up? g. How the window panel unit is removed from the fuselage structure for maintenance? 2. Write down the need that the design of this cabin window satisfies. 3. Write down constraints that might be used in the design process of this window. 4. Specify criteria and weightings, which might be used for evaluation of the optimal design
