C5 Summary 1

How does perspective sketching differ from orthographic projection in terms of representing an object?

• Perspective sketching provides a more abstract representation.

• Perspective sketching provides a more realistic representation.

• Orthographic projection provides a more realistic representation.

• Orthographic projection provides a more abstract representation.

Answer explanation

Perspective sketching captures depth and realism by simulating how objects appear to the eye, making it more relatable. In contrast, orthographic projection shows multiple views without depth, making it less realistic.

Why is orthographic projection important in the manufacturing process?

• It provides a 3D view of the object.

• It shows the true shape and all dimensions required for manufacturing.

• It allows for artistic interpretation of the object.

• It simplifies the object into basic shapes.

Answer explanation

Orthographic projection is crucial in manufacturing as it accurately represents the true shape and all necessary dimensions of an object, ensuring precise fabrication and assembly.

What are the main components of a CAD system?

• A drawing board, a pencil, and an eraser.

• An input device, a processor, and an output device.

• A scanner, a printer, and a monitor.

• A mouse, a keyboard, and a monitor.

Answer explanation

A CAD system primarily consists of an input device (like a mouse), a processor (the computer), and an output device (like a monitor). This combination allows for the creation, manipulation, and visualization of designs.

How has CAD changed the field of design compared to manual drafting?

• CAD has made design more time-consuming.

• CAD has replaced manual drafting, making design more efficient.

• CAD has made manual drafting more popular.

• CAD has no significant impact on design.

Answer explanation

CAD has significantly improved design efficiency by automating tasks and allowing for easier modifications, thus replacing manual drafting. This advancement has streamlined the design process, making it faster and more accurate.

In what way can a CAD system be integrated with a manufacturing system?

• By using a shared internet connection.

• By linking it to a computer-aided manufacturing system.

• By using manual data entry.

• By printing designs and manually transferring them.

Answer explanation

The correct choice is linking to a computer-aided manufacturing system, as it allows seamless integration of design and production processes, enhancing efficiency and accuracy compared to manual methods or shared connections.

What is the primary advantage of using perspective sketches in design?

• They provide exact dimensions for manufacturing.

• They offer a realistic view that is easy to understand.

• They simplify complex objects into basic shapes.

• They are easier to create than orthographic projections.

Answer explanation

The primary advantage of perspective sketches is that they offer a realistic view that is easy to understand, making it simpler for clients and stakeholders to visualize the design compared to other methods.

Which of the following best describes the role of orthographic projections in design?

• They are used for artistic interpretations.

• They provide a realistic 3D view of the object.

• They show multiple views to represent the true shape and dimensions.

• They are used to create abstract designs.

Answer explanation

Orthographic projections are essential in design as they provide multiple views of an object, accurately representing its true shape and dimensions, which is crucial for technical drawings and engineering designs.

How does the integration of CAD and CAM systems benefit the manufacturing process?

• It increases the need for manual adjustments.

• It allows for seamless transition from design to production.

• It complicates the design process.

• It reduces the accuracy of the final product.

Answer explanation

The integration of CAD and CAM systems streamlines the workflow, enabling a seamless transition from design to production. This enhances efficiency and reduces errors, unlike the other options which suggest complications or inaccuracies.

What reasoning might a designer use to choose CAD over manual drafting?

• CAD is more traditional and widely accepted.

• CAD allows for faster and more precise modifications.

• Manual drafting is more accurate.

• Manual drafting is easier to learn.

Answer explanation

Choosing CAD allows designers to make faster and more precise modifications compared to manual drafting, which can be time-consuming and less accurate. This efficiency is crucial in modern design processes.

Why might a designer choose to use orthographic projection instead of perspective sketching?

• To provide a more artistic view of the object.

• To ensure all necessary dimensions are included for manufacturing.

• To create a more abstract representation.

• To simplify the design process.

Answer explanation

A designer might choose orthographic projection to ensure all necessary dimensions are included for manufacturing, as it provides precise measurements and clear views of each side of the object, unlike perspective sketching.
