d. Projections of a pyramid lying on one of its slant edge HP

The sequence of obtaining the projections of a pyramid lying on one of its slant edge on HP is shown in figure 5. In step-1, The FV and TV of the pyramid in the simple projection is drawn such that in the, top view the slant edge (line cd)  on which it will rest on ground is drawn parallel to HP  ( parallel to XY line) in the. In the front view this edge will be  line c’ o’.  In step-2, the object is then rotated such that the pyramid lies with its edge o’c’ on HP. i.e. in the front view,  o’c’ lies on XY line.  Project the Top view from this Front view.
