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 edgeview and cuttingplane 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. Draw the intersection of an inclined line with the principal line of a solid. Draw the intersection of a principal line with the principal line of a solid. Draw the intersection of two planes using the edgeview and cutting plane methods. Draw the intersection of an oblique plane with the oblique plane of a solid. Draw the intersection of an oblique plane with an inclined plane of a solid. Draw the intersection of an oblique plane with the principal plane of a solid. Draw the intersection of a plane with a prism. Draw the intersection of two prisms. Draw the intersection of a prism with a pyramid. Draw the intersection of two pyramids. Draw the intersection of a line with a cylinder. Draw the intersection of a line with a cone. Draw the intersection of a plane with a cylinder. Draw the intersection of a plane with a cone. Draw the intersection of two cylinders. Draw the intersection of a cone with a cylinder. Draw the intersection of two cones. Draw the intersection of a line with a surface of revolution.
