First Quarterly Examination in SMAW NC I

Which type of line is used to represent the outline of an object in technical drawing?

• Center line

• Construction line

• Hidden line

• Object line

What does a dashed line typically indicate in technical drawing?

• Construction lines

• Dimension lines

• Leader lines

• Visible edges

In technical drawing, which line type is used to show features that are not directly visible from the current viewpoint?

• Center line

• Hidden line

• Object line

• Phantom line

What is the purpose of a center line in technical drawing?

• Indicate hidden features

• Provide dimensions

• Represent symmetry or axes

• Show the boundary of an object

In technical drawing, when employing extension lines for dimensioning, what is the specific purpose of the extension line beyond simply extending from the object's boundaries?

• Denote construction lines for auxiliary views

• Establish symmetry

• Indicate hidden features

• Provide a reference for dimension placement

In which type of drawing do you represent a three-dimensional object using a single view?

• Axonometric drawing

• Isometric drawing

• Orthographic drawing

• Perspective drawing

What is the key characteristic of an isometric drawing?

• All lines are parallel

• Lines are at right angles to each other

• Lines converge to a vanishing point

• The drawing is in 2D only

How many principal views are typically used in an orthographic drawing?

• 1

• 2

• 3

• 4

In orthographic drawing, what is the purpose of the front, top, and right side views?

• To depict the object's features from various perspectives

• To provide detailed measurements

• To represent the object in three dimensions

• To show different angles of the object

What is a disadvantage of isometric drawings compared to orthographic drawings?

• Isometric drawings are harder to understand

• Isometric drawings can distort proportions

• Orthographic drawings are more time-consuming to create

• Orthographic drawings lack depth perception
