1. Which of the following is NOT a fundamental rule of dimensioning?
Avoid crossing dimension lines.
Place dimensions where they are most visible.
Dimension every feature of the object twice.
Dimension from a common baseline.
2. What is the primary purpose of extension lines in dimensioning?
To indicate the overall size of an object.
To extend the object's outline for clarity.
To indicate where the dimension applies.
To show hidden lines of an object.
3. A line is a thin, solid line that terminates with arrowheads and indicates the extent of the dimension.
4. Dimensions should be placed the view to which they apply.
5. Explain the difference between chain dimensioning and baseline dimensioning.
