Chapter 4: Engineering technique

What does CAD stand for in the context of engineering drawings?

• Computer Assisted Drawing

• Computer Aided Design

• Calculated Automatic Design

• Creative Art Design

Which feature of CAD software helps in maintaining consistency across different drawings?

• Repetitive features

• Blocks

• Editing

• Accuracy

What is a major advantage of using CAD over manual drawing?

• It requires more skills

• It is less accurate

• It offers greater precision

• It uses more paper

How does CAD software enhance the process of making changes to a drawing?

• By permanently altering the original drawing

• By using Undo and Redo features

• By requiring new drawings each time

• By damaging the drawing surface

What is the purpose of orthographic drawing techniques?

• To represent three-dimensional solids on a two-dimensional surface

• To create artistic representations

• To use as many colors as possible

• To draw objects from memory

Which projection is also known as English projection?

• Third-angle projection

• Second-angle projection

• First-angle projection

• Fourth-angle projection

What is the main view in the first-angle projection known as?

• Side view

• Elevation

• Top view

• Bottom view

What is the main difference in the plan view between first-angle and third-angle projections?

• In third-angle projection, the plan view is drawn from below the elevation.

• In third-angle projection, the plan view is drawn from above the elevation.

• In third-angle projection, no plan view is drawn.

• There is no difference in the plan view between the projections.

What is the purpose of using auxiliary views in engineering drawings?

• To show the material of the component

• To show the true outline of the component when it cannot be shown in the main views

• To indicate the weight of the component

• To show the color of the component

Which view is drawn from the same end as the plan view in a third-angle projection?

• Top view

• Side view

• End view

• Bottom view
