1. Define orthographic projection.

2. How is orthographic projection different from perspective projection? Use a sketch to highlight the differences.

3. Define multiview drawings and make a simple sketch of an object using multiviews.

4. Define frontal, horizontal, and profile planes.

5. List the six principal views.

6. Define fold lines.

7. List the space dimensions found on a front view, top view and profile view.

8. Define a normal plane.

9. Define an inclined plane.

10. Define an oblique plane.

11. List the 8 rules of orthographic projection.

12. Why is visualization important in engineering and technical graphics? Is it useful in any other fields? Are you born with the ability to visualize, or is it learned?

13. What is the relationship between faces and edges in the visualization of an object?

14. Do planar and curved surfaces reveal themselves differently on an object?

15. Explain the different visual results of additive and subtractive combinations of two solids. Are there ways of arranging additive or subtractive combinations such that the resulting object doesn't look any different?

16. What are the differences in the way normal, inclined, and oblique faces are visualized? How are cutting planes used to generate these faces?

17. Define a development. How is it used in visualization?

18. Name the person credited with demonstrating multiview projections in a book published in 1528.
