A company is designing a new smartphone. Which of the following best explains why technical drawings are essential?
They make the phone look aesthetically pleasing.
They ensure all parts fit together correctly before manufacturing.
They increase marketing potential.
They eliminate the need for 3D models.
A student is learning CAD software after mastering hand-drawn sketches. How does this benefit their technical drafting skills?
It replaces manual drafting completely.
It reduces the need for accurate measurements.
It allows for easier modifications and 3D modeling.
It eliminates the need to understand line symbols.
Why is technical drawing considered a global language in engineering and architecture?
It uses colors to distinguish different parts.
It follows standardized symbols and formats understood worldwide.
It allows for creative freedom in engineering.
It eliminates the need for measurements.
A mechanical engineer wants to create a 3D-looking technical drawing that still allows for accurate measurements. Which method should they use?
Orthographic Projection
Isometric Drawing
Perspective Drawing
Freehand Sketching
Why is an isometric drawing preferred over a perspective drawing in technical drafting?
It maintains accurate measurements in all three dimensions.
It looks more realistic.
It allows for better shading and depth perception.
It can only be used for small objects.
If an engineer draws a cube using isometric projection, what angle should the edges form with the horizontal?
60 Degrees
30 Degrees
45 Degrees
90 Degrees
A glass-box method is used to visualize orthographic projections. If the box is unfolded, how many primary views are available?
