A) section
B) cut-a-way
C) detail
D) rotated

Accepted Answer

A cut-a-way view is used to reveal the inner workings of a part that would be obscured by its surface. This view typically includes a freehand break line that outlines the area that has been imaginarily removed. Section views are used to show the internal and external features of a part, while detail views are used to magnify a specific area of the part. Rotated views are used to show the part from a different angle.

Question 12

____ show an alternate position of a moving part or the extent of motion such as the on/off position of a light switch.They can also be used as a place holder for a part that will be added later.
A) Phantom lines
B) Leaders and arrows
C) Section lines
D) Break lines

Accepted Answer

Phantom lines are used to show an alternate position or extent of motion of a part. They can also be used as placeholders for parts that will be added later. Leaders and arrows are used to indicate dimensions or notes. Section lines are used to show where a section has been taken in a view. Break lines are used to indicate where a part of the object has been intentionally broken off to save drawing space.

Question 13

____ lines show the same features as object lines except that the corners, edges, and curved surfaces cannot be seen because they are hidden behind the surface of the object.
A) Extension
B) Hidden
C) Dimension
D) Center

Accepted Answer

Hidden lines are used to represent features that are not visible from the current view but are necessary to fully understand the object. They are typically shown using a dashed line style.
