- Sketch the symbol for third-angle projection.
- List the six principal views of projection.
- Sketch the top, front, and right-side views of an object of your design having normal, inclined and oblique surfaces.
- In a drawing that shows top, front, and right-side view, which two views show depth? Which view shows depth vertically on the sheet? Which view shows depth horizontally on the drawing sheet?
- What is the definition of a normal surface? An inclined surface? An oblique surface?
- What are three similarities between using a CAD program to create 2-D drawing geometry and sketching on a sheet of paper? What are three differences?
- What dimensions are the same between the top and front view: width, height, or depth? Between the front and right side view? Between the top and right-side view?
- List two ways of transferring depth between the top and right-side views.
- If surface A contained corners 1,2,3,4, and surface B contained corners 3,4,5,6, what is the name of the line where surfaces A and B intersect?
- If the top view of an object shows a drilled through hole, how many hidden lines would be necessary in the front view to describe the hole?
