Both long break lines and short break lines are thick lines.True or false

False.

False. Both long break lines and short break lines are thin lines.

To determine whether both long break lines and short break lines are thick lines, we need to understand what long break lines and short break lines represent.

In technical or engineering drawings, long break lines are used to indicate a section or a portion of an object that has been removed for clarity, such as when showing the internal structure of a machine. On the other hand, short break lines are used to indicate that a part of an object, such as a long continuous piece, has been intentionally omitted for space-saving reasons. These break lines are usually drawn as thick lines to make them easily distinguishable from other lines on the drawing.

Therefore, the statement is true: both long break lines and short break lines are typically represented as thick lines in technical drawings.
