When engineers draw automobile engines, they typically need to show the internal features. To do this, which drawing technique do they need to use?

A. Dimensioning
B. Assembling
C. Sectioning
D. Cross-sectioning



Answer :

Final answer:

Engineers use cross-sectioning to show internal features of automobile engines.


Explanation:

When engineers draw automobile engines and need to show the internal features, they typically use the drawing technique of cross-sectioning.

This technique involves cutting the object in half or exposing its internal features to reveal details that would not be visible in a regular view. By creating a cross-section, engineers can provide a clear representation of the internal components of the engine.

For instance, by cross-sectioning an engine block, engineers can display the arrangement of pistons, cylinders, valves, and other internal parts to aid in design, analysis, and communication within the engineering team.
