		Class	D.Lab	P.Lab
SURFACE DEVELOPMENT		3	10
Theory	Define the term "surface development." Describe how a surface is composed.
Development	Develop the lateral surfaces of a prism, pyramid, cylinder, and cone. Develop the lateral surfaces of a prism and cylinder combination. Develop the lateral surfaces of cones and transition pieces.
ESTABLISHMENT OF TRUE LENGTH		1	3
Theory	State in which plane of projection true length is shown. State which conditions must be met to establish the true length of a line by revolution.
Development	Develop the edge view of a plane by revolution. Develop the true surface of a plane by revolution.
INTERSECTION OF SURFACES		6	77
Theory	Define intersecting and nonintersecting lines.
Development	Draw the intersection of a line with a plane using the edge-view and cutting-plane methods. Draw the intersection of an oblique line with a solid having an oblique surface. Draw the intersection of an oblique line with a solid having an inclined surface. Draw the intersection of an oblique line with the principal plane of a solid.
