What is orthographic projection?
A method of representing a three-dimensional object in two dimensions
A cooking technique
A form of dance
A type of surgical procedure

Name the three principal views in orthographic projection.
Inside view, outside view, and upside-down view
Front view, top view, and side view
Left view, right view, and bottom view
Diagonal view, horizontal view, and vertical view
What is the purpose of orthographic projection in technical drawing?
To represent a 3D object in 2D by showing multiple views from different angles
To add color and texture to the drawing
To create a 3D hologram of the object
To make the object appear larger than it actually is
Explain the difference between first angle and third angle projection in orthographic projection.
First angle projection is used for 2D drawings, while third angle projection is used for 3D drawings.
First angle projection is commonly used in Europe and Asia, while third angle projection is commonly used in North America.
First angle projection shows the top view on the left side, while third angle projection shows the top view on the right side.
First angle projection is more accurate than third angle projection.
What are the types of lines used in orthographic projection?
Solid lines, dotted lines, dashed lines, wavy lines
Visible lines, hidden lines, center lines, and dimension lines
Vertical lines, horizontal lines, diagonal lines, curved lines
Thick lines, thin lines, broken lines, jagged lines
What is the importance of orthographic projection in architecture?
Using 3D glasses to view architectural plans
Creating abstract designs
Adding color to architectural drawings
Accurate representation of 3D objects on a 2D surface
Explain the concept of hidden lines in orthographic projection.
Hidden lines are drawn with a thicker line weight than visible lines
Hidden lines are used to indicate the direction of light source
Hidden lines are used to represent the color of the object
Hidden lines are used to represent edges or lines that are not visible in the current view but are present in the object.
What are the advantages of using orthographic projection in technical drawing?
Provides color and texture details
Accurate representation of object's shape and size
Saves time in drawing
Enhances creativity in design
How does orthographic projection help in visualizing 3D objects in 2D drawings?
It makes the object appear larger than it actually is
It distorts the object and hides important details
It accurately represents the object from different views and shows all the dimensions and details.
It only shows the object from one view
What is the purpose of isometric projection in technical drawing?
To represent a 3D object in 2D by showing multiple views from different angles
To create a 3D hologram of the object
To add color and texture to the drawing
To make the object appear larger than it actually is
Explain the concept of foreshortening in technical drawing.
Foreshortening is used to represent the color of the object
Foreshortening is a technique to create abstract designs
Foreshortening is a method of representing a three-dimensional object in two dimensions
Foreshortening is a type of surgical procedure
What are the applications of technical drawing in engineering?
Creating abstract designs
Accurate representation of 3D objects on a 2D surface
Using 3D glasses to view architectural plans
Adding color to architectural drawings
