Dimensions - Technical Drawing

What is the purpose of orthographic projection in technical drawing?

• To create a three-dimensional representation of an object

• To represent the object in as much detail as possible on a single plane

• To provide multiple views of an object on different planes

• To add artistic effects to the drawing

In isometric drawing, what is the angle between the axes?

• 45 degrees

• 60 degrees

• 90 degrees

• 120 degrees

Which dimensioning standard uses symbols to represent features and does not rely heavily on numerical values?

• ISO

• ANSI

• Geometric Dimensioning and Tolerancing (GD&T)

• British Standards (BS)

How many principal views are typically used in orthographic projection?

• 2

• 3

• 4

• 6

What is the main characteristic of an isometric drawing?

• It shows the object's dimensions as they appear to the observer

• It distorts the object's dimensions to reveal hidden details

• It represents the object without perspective distortion

• It only shows the top view of the object

Which of the following is NOT a common practice in dimensioning?

• Placing dimensions inside the object whenever possible

• Repeating dimensions on the same drawing

• Providing dimensions to hidden features as necessary

• Keeping dimensions clear of the object

In orthographic projection, which view is typically placed directly above the front view?

• The top view

• The bottom view

• The right side view

• The isometric view

What does it mean if a line is shown as a dashed line in an isometric drawing?

• The line is a centerline

• The line represents an edge that is hidden from view

• The line is part of the dimensioning

• The line indicates a fold or bend

Which dimensioning standard is primarily used in the United States?

• ISO

• ANSI

• GD&T

• BS

In dimensioning, what is the purpose of a leader line?

• To indicate the direction of the north

• To connect a dimension number or note to a specific feature

• To show the path of motion

• To highlight the main dimensions
