1. Draw the projections of the cone assuming that the cone is resting with its base on v.P.


2. Divide the circle into a number of equal parts and draw the corresponding generators in the
   top view.


3. Redraw the top view so that the axis makes 45° with xy. This is the fmal top view.


4. Obtain the final view by projection.
