Technical Drawing Lines Quiz

What is the main purpose of a visible (object) line in a technical drawing?

• To indicate measurement references

• To represent hidden features

• To show the edges and shape of an object

• To extend a dimension beyond an object

Which type of line is used to represent features that are not visible from a particular view?

• Center Line

• Hidden Line

• Visible Line

• Extension Line

What is the correct style of a hidden (invisible) line?

• A thick, solid line

• A series of evenly spaced dashes

• A combination of short and long dashes

• A thin, solid line

What type of line is used to indicate the center of circles or symmetrical objects?

• Dimension Line

• Extension Line

• Center Line

• Leader Line

A dimension line is used to:

• Show the size of an object with numerical values

• Represent hidden details of an object

• Extend a reference from an object's surface

• Indicate the midpoint of a drawing

What is the function of an extension line?

• To represent the outer boundary of an object

• To connect a dimension line to the object being measured

• To indicate hidden features

• To guide notes and annotations in a drawing

What type of line is typically used to connect a note, symbol, or reference to a specific part of the drawing?

• Visible Line

• Construction Line

• Center Line

• Leader Line

Which type of line is often drawn very lightly and used as a guide for technical drawings?

• Construction Line

• Hidden Line

• Extension Line

• Dimension Line

A center line is typically represented by:

• A continuous thick line

• A thin, solid line

• A long dash followed by a short dash in repetition

• A series of small evenly spaced dots

Why are construction lines important in technical drawing?

• They help in adding shading and texture

• They provide guidelines for the final drawing without being part of it

• They are used to represent an object's edges

• They indicate dimensions in a drawing
