Construction Tools and Multiview Drawings

What is the primary purpose of orthographic projection in multiview drawings?

• To create a 3D model of the object

• To show how the object looks from the top

• To represent the object from several views accurately

• To enhance the artistic appeal of the drawing

How many principal views are typically used in orthographic projection?

• One

• Two

• Three

• Four

Which view is NOT one of the three commonly used views in orthographic projection?

• Top view

• Front view

• Side view

• Angle view

What dimensions does the top view show?

• height

• depth

• width

• The layout of the object's top surface

In orthographic projection, what does the top view primarily show about an object?

• The depth of an object

• The pictorial view

• The isometric view

• The layout of the object's top surface

Orthographic projection is formed on to a plane by _________.

• Perspective

• Parallel lines

• Curved lines

• Vanishing points

What is the purpose of using dashed lines in orthographic drawings?

• To indicate hidden edges

• To show the object's color

• To represent the ground line

• To highlight the most important part of the drawing

In orthographic projection, how is the front view determined?

• It is side that shows the most features and details.

• It is the view that shows the object's height and width.

• It is chosen randomly.

• It is the side facing the observer.

Why is it important to include dimensions in an orthographic drawing?

• To provide a reference for the drawing's scale

• To make the drawing look more complex

• To indicate the drawing's artistic style

• To ensure the object can be accurately reproduced for manufacturing or construction

What does the term "projection plane" refer to in orthographic projection?

• The surface on which the 3D object is drawn

• The imaginary flat surface onto which the view of the object is projected

• The physical table or board used for drawing

• The background of the drawing
