Intro to Drafting

An engineer is creating a technical drawing of a machine part. He needs to indicate a hole’s center position. Which line should he use?

• Object Line

• Hidden Line

• Center Line

• Phantom Line

A designer wants to show a removable cover in an alternate position on a technical drawing. Which line type should he use?

• Phantom Line

• Extension Line

• Cutting Plane Line

• Dimension Line

A student is drawing an orthographic projection and wants to show a feature that is not visible from the chosen view. Which line should be used?

• Hidden Line

• Object Line

• Center Line

• Leader Line

An architect is drawing a precise horizontal line using a T-square. To draw a perfect 45-degree line, which additional tool should be used?

• Compass

• Triangle

• Protractor

• Ruler

A drafter is making a technical drawing that requires precise curves and arcs. Which tool should they use?

• Compass

• Protractor

• French Curve

• Triangle

While creating a scaled-down drawing of a building, an engineer wants to use a tool that allows her to read measurements at different ratios. Which tool should she use?

• Architect’s Scale

• Protractor

• Triangle

• Compass

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
