!.Draw the projections of a heagonal p ramid with the side of base !mm and ais % mm long which is resting with a slant face on +.0. such that the ais is parallel to 3.0. 4ollow the change of position method.#.A cone of base #%mm diameter and ais &mm long is resting on its base on +.0. It is cut b a section plane perpendicular to 3.0. and %mm awa from the ais. Draw the sectional side iew of the cut solid.%.A ertical cone with diameter of base * mm and ais 1 mm long is penetrated b a hori5ontal c linder of % mm diameter. 6he ais of the c linder intersects the ais of the cone at a point of ! mm from the base. Draw the projections of the solids. how the lines of inter section.&.A point /A/ is 2mm aboe +.0. and 2%mm in front of 3.0. another point /7/ is !%mm behind 3.0. and #mm below +.0.
