DMD Design & Product Development 2

Question 1

An engineer wants a CAD model where changing the overall length automatically updates hole positions and fillet sizes. Which modeling approach best supports this?

Accepted Answer

Parametric, feature-based modeling

Answer

Parametric modeling links features through dimensions and constraints so changes propagate automatically.

Question 2

Which document lists every part, subassembly, and quantity needed to build a product?

Accepted Answer

Bill of Materials (BOM)

Answer

The BOM is the structured list of components and quantities required to manufacture an assembly.

Question 3

A team performs Design for Assembly (DFA) analysis. Which change most directly supports DFA goals?

Accepted Answer

Reducing part count by combining components

Answer

DFA aims to minimize parts and simplify handling and insertion, so consolidating parts is a primary strategy.

Question 4

In GD&T, what does a datum reference frame establish?

Accepted Answer

A coordinate system from which features are located and measured

Answer

Datums A, B, and C create a reference frame that constrains the part for measurement and inspection.

Question 5

Which product development stage typically uses a low-fidelity prototype to test form and basic ergonomics quickly?

Accepted Answer

Concept development

Answer

Early concept prototypes are cheap, fast models used to evaluate form, fit, and user interaction before detailed design.
