ETRY Problem 63.—To show the projections and true form ofthe section of a polyhedron. The section is a right Hned figure which can be deter-mined by finding the vertices from the intersections of theedges with the cutting plane, or the sides of the figure canbe determined by finding the… … Fig. 165. bring the cutting plane perpendicular to H or V the workis somewhat simplified. One projection of the requiredsection is then a straight, line coinciding^with the obliquetrace of the cutting planp. From this the vertices of theother projection can readily be projected. Problem 64.—To show…
