L. Fig. 15 shows a similar problem solved in the first quadrantand serves to show the arrangement of views for the firstquadrant. By using similar methods of projection a third view of anyobject may be obtained when two views are given. Thus: aplan view may be found from the elevation and end view; or anelevation may be found from the end view and plan. PROBLEMS IN PROJECTION II. Draw the plan, elevation, and right end view of a cube with edges2 long. Let the upper face of the cube be parallel to and i below H with. —>\ 2y,^ > 4^— 1-1 t-H 1 Square Z .-L
