What is the process known as sketching?

Back

Drawing basic shapes to define size and shape of features

Answer explanation

Sketching involves drawing basic shapes to define the size and shape of features, serving as a preliminary step in design before more detailed work like 3D modeling or prototyping.

Front

What are edge treatments in 3D modeling?

Back

Applying fillets and chamfers to enhance appearance

Answer explanation

Edge treatments in 3D modeling refer to applying fillets and chamfers, which smooth or bevel edges to enhance the model's appearance and functionality, making it visually appealing and easier to manufacture.

Front

What is a prototype?

Back

A full-sized physical model that is functional.

Answer explanation

A prototype is typically a full-sized physical model that is functional, allowing for testing and evaluation of design concepts in real-world conditions.

Front

What is an offset work plane?

Back

A plane parallel to an existing surface at a specified distance.

Answer explanation

An offset work plane is defined as a plane that is parallel to an existing surface but located at a specified distance from it. This allows for precise modeling and design in various applications.

Front

What is a sub-assembly?

Back

A group of pre-assembled parts treated as a single unit

Answer explanation

A sub-assembly is defined as a group of pre-assembled parts treated as a single unit, which allows for easier assembly and organization within larger products. This distinguishes it from single parts or theoretical concepts.

Front

What are degrees of freedom in design?

Back

Different ways parts can move relative to one another

Answer explanation

Degrees of freedom refer to the different ways parts can move relative to one another in a design. This concept is crucial for understanding how components interact and function together, making it the correct choice.

Front

What are drive constraints in modeling?

Back

Simulating movement of parts through specified steps

Answer explanation

Drive constraints refer to simulating the movement of parts through specified steps, allowing for precise control and analysis of mechanical systems in modeling.

Front

What is the maximum number of bike frames you can ship in one box if each frame weighs 5.67 pounds and the limit is 20 pounds?

Back

Three frames

Answer explanation

To find the maximum number of bike frames, divide the weight limit by the weight of each frame: 20 pounds ÷ 5.67 pounds/frame = 3.52. Since you can't ship a fraction of a frame, the maximum is 3 frames.

Front

What is minimum clearance space?

Back

The gap that must exist between two mating parts

Answer explanation

Minimum clearance space refers to the necessary gap between two mating parts to ensure proper function and avoid interference. This definition aligns with the correct answer choice.

Front

What is the purpose of hatch marks or section plans?

Back

Indicate material textures, dimensions, or finishes

Answer explanation

Hatch marks or section plans are used to indicate material textures, dimensions, or finishes in architectural and engineering drawings, helping to convey important details about the design.
