SHS Technical Drawing Quiz

Match the following descriptions with the correct type of pictorial drawing.

• Centerline

• Oblique pictorial where height, width, and depth are represented at full scale.

• Construction Line

• A line which defines the center of arcs, circles, or symmetrical parts.

• Cabinet Pictorial

• Oblique pictorial where depth is represented as half scale compared to the height and width scale.

• Cavalier Pictorial

• Lightly drawn lines to guide drawing other lines and shapes.

Answer explanation

A Cabinet Pictorial is an oblique drawing where depth is shown at half scale compared to height and width, making it easier to visualize three-dimensional objects on a two-dimensional surface.

What does a Center Line define?

• The measurement associated with an object's front-to-back dimension.

• A line which defines the center of arcs, circles, or symmetrical parts.

• A line which represents distance.

• A formal graphical representation of an object.

Answer explanation

A Center Line is crucial in technical drawings as it defines the center of arcs, circles, or symmetrical parts, ensuring accurate representation and alignment in design. This makes the second choice the correct answer.

What is the purpose of a Construction Line?

• To represent where a dimension starts and stops.

• To guide drawing other lines and shapes.

• To define the center of arcs, circles, or symmetrical parts.

• To represent distance.

Answer explanation

A Construction Line is primarily used to guide drawing other lines and shapes, providing a reference that helps in maintaining alignment and proportions during the drafting process.

What is an Ellipse?

• A line which represents where a dimension starts and stops.

• A regular oval shape, traced by a point moving in a plane.

• A line which defines the center of arcs, circles, or symmetrical parts.

• A formal graphical representation of an object.

Answer explanation

An ellipse is defined as a regular oval shape, created by a point moving in a plane, making the second answer choice the correct one. The other options describe different geometric concepts.

What does a Dimension Line represent?

• A line which represents distance.

• A line which defines the center of arcs, circles, or symmetrical parts.

• A line which represents where a dimension starts and stops.

• A line along which two surfaces of a solid meet.

Answer explanation

A Dimension Line represents distance by indicating the extent of a measurement. It shows where a dimension starts and stops, making it essential for understanding the size of objects in technical drawings.

What is a grid in technical sketching and drawing?

• A tool used for measuring angles

• A network of lines that cross each other to form a series of squares or rectangles

• A type of line that represents an edge not directly visible

• A method of drawing without instruments

Answer explanation

A grid in technical sketching is defined as a network of lines that intersect to create squares or rectangles, providing a reference for accurate drawing and layout.

What does the term "height" refer to in technical drawing?

• The width of an object

• The depth of an object

• The measurement associated with an object's top-to-bottom dimension

• The length of an object

Answer explanation

In technical drawing, "height" specifically refers to the measurement associated with an object's top-to-bottom dimension, distinguishing it from width and length, which refer to side-to-side and front-to-back dimensions, respectively.

An isometric sketch is a form of pictorial sketch in which all three drawing axes form equal angles of (a)   degrees with the plane of projection.

• A sketch with only two dimensions
• A form of pictorial sketch in which
• A sketch that uses only horizontal
• A sketch that uses only vertical li

Answer explanation

An isometric sketch is a type of pictorial sketch where the three axes are equally spaced at 120 degrees. This allows for a three-dimensional representation on a two-dimensional surface, making it distinct from sketches with only horizontal or vertical lines.

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

• To indicate the main axis of an object

• To show the top view of an object

• To indicate dimensions of arcs, circles, and detail

• To represent hidden edges

Answer explanation

A leader line is used in technical drawings to indicate dimensions of arcs, circles, and details, helping to clarify measurements and features of the object being represented.

"Line weight" in technical drawing refers to the (a)   of a line.

• The length of a line
• The color of a line
• The thickness of a line, characteri
• The angle of a line

Answer explanation

In technical drawing, "line weight" specifically refers to the thickness of a line, which can be categorized as thick or thin. This characteristic helps convey different levels of importance and clarity in the drawing.
