What is isometric projection?

• A method of visually representing three-dimensional objects in two dimensions.

• A method of visually representing one-dimensional objects in two dimensions.

• A method of visually representing two-dimensional objects in one dimension.

• A method of visually representing two-dimensional objects in three dimensions.

Which of the following is NOT a characteristic of isometric projection?

• All three axes are equally foreshortened

• No vanishing points exist

• Parallel lines remain parallel

• All of the given options are characteristics of isometric projection.

What is a sectional view?

• A sectional view is a type of drawing that shows the object from a different angle.

• A sectional view is a type of drawing that shows the object in its entirety.

• A sectional view is a type of drawing that shows the object in motion.

• A sectional view is a type of drawing that shows the internal structure of an object by cutting it along a specific plane and removing a portion of it.

Which of the following is NOT a type of sectional view?

• Orthographic view

• Elevation view

In orthographic projection, how many views are typically used to represent an object?

• 1

• 3

• 2

• 4

What is the purpose of using sectional views?

• To show internal details of an object

• To demonstrate the assembly process of an object

• To show the dimensions of an object

• To highlight the surface finish of an object

Which of the following is NOT a characteristic of sectional views?

• They do not show dimensions

• They are used to show the shape of an object

• They are used to reduce the number of hidden lines

• They are used to show internal features

What is the purpose of using isometric projection?

• To simplify the process of drawing three-dimensional objects.

• To create a realistic representation of three-dimensional objects.

• To add depth and dimension to two-dimensional drawings.

• To represent three-dimensional objects in a two-dimensional space without distortion of the angles.
