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

How many principal views are typically used in orthographic projection?

• 2

• 3

• 4

• 6

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

In isometric drawings, how are circles typically represented?

• As perfect circles

• As ellipses

• As squares

What is the main advantage of using orthographic projection in technical drawings?

• It allows for artistic expression

• It provides a realistic view of the object

• It accurately represents the dimensions of the object

• It simplifies complex shapes into basic forms

Why is it important to follow dimensioning standards in technical drawing?

• To ensure the drawing is aesthetically pleasing

• To make the drawing process faster

• To ensure clarity and uniformity across industries

• To use as many dimensions as possible
