The Cone.

Fig. 173 shows the construction lines necessary to outline the cone. The apex is directly above the centre of the base when the base is horizontal. The base of the cone is a circular surface and will appear as a circular tablet.

To show a part cut from a cone, proceed in the same manner as with the cylinder. The necessary construction lines are shown in fig. 174. Such objects as an ink bottle, a funnel and a top are similar in form to the cone. See fig. 172.
