Understanding Lines in Technology

What is the definition of a line in basic technology?

• A line is a point that has no dimensions.

• A line is a straight one-dimensional figure that extends infinitely in both directions.

• A line is a solid object with width and height.

• A line is a curved two-dimensional shape.

Name three types of lines used in technical drawings.

• Wavy lines

• Solid lines, Dashed lines, Dotted lines

• Curved lines

• Zigzag lines

What is the purpose of a solid line in technical drawings?

• To show dimensions and measurements.

• To indicate hidden edges of objects.

• To represent visible edges and outlines of objects.

• To represent shading and texture effects.

How does a dashed line differ from a dotted line?

• A dashed line is thicker than a dotted line, which is always thin.

• A dashed line is made up of solid blocks, whereas a dotted line is made of lines.

• A dashed line is always straight, while a dotted line can be curved.

• A dashed line has longer segments with spaces, whereas a dotted line consists of short dots.

What type of line is used to represent hidden edges?

• Dashed line

• Wavy line

• Dotted line

• Solid line

Explain the use of center lines in engineering drawings.

• Center lines indicate the centers of circles and symmetrical features, aiding in dimensioning and reference.

• Center lines are used to indicate the thickness of materials.

• Center lines are only necessary for 3D models, not 2D drawings.

• Center lines are primarily for aesthetic purposes in design.

What is the significance of a thick line in a drawing?

• A thick line signifies emphasis or importance in a drawing.

• A thick line shows the background elements in a drawing.

• A thick line is used to represent shadows only.

• A thick line indicates a measurement in a drawing.

Identify a type of line that indicates a dimension in a drawing.

• Reference line

• Guide line

• Dimension line

• Construction line

What type of line is commonly used to show the outline of an object?

• Contour line

• Dotted line

• Dashed line

• Solid line

How are construction lines used in technical drawing?

• Construction lines are used to add color to drawings.

• Construction lines serve as guides for accurate placement and alignment in technical drawings.

• Construction lines are only used for decorative purposes.

• Construction lines are permanent features in technical drawings.
