What is the purpose of a dashed thin line in technical drawings?

• Used for limits of partial or interrupted views and sections if the limit is not an axis.

• Used for visible outlines and edges.

• Used for hidden outlines and edges.

• Used on Cutting planes.

What type of line is used for centre lines and lines of symmetry?

• Long dash short dashed line

• Continuous thin straight with zigzags

• Chain thin double dash

• Continuous thin irregular

For what purpose is a chain thin double dash line used?

• Fold Lines

• Chain thin

What is the specific use of a chain thin and thick at both ends?

• Used for hidden outlines and edges.

What is the term used to describe the small line that connects the dimension line to the feature being dimensioned?

• Leader

• Dimension line

• Arrow

• Gap

What should be present between the leader and the line of the drawing?

• A large gap

• No gap
