(Optional) Interpret line weights.

Interpretation should include

• light-weight lines (e.g., extension lines, dimension lines)
• medium-weight lines (e.g., visible outline lines, hidden outline lines)
• heavy-weight lines (e.g., outlines of cuts, outlines of sectioned objects).

Process/Skill Questions:

• What information does each type of line weight convey?
• Where should dimension lines be located on drawings? Why?
• What line weight can be used to depict things that do not actually exist in physical form?
