What are break lines used for in a print?

Break lines are used in technical drawings and prints to indicate the boundaries of an imaginary section. They serve the purpose of simplifying complex parts or assemblies by visually removing a portion of the drawing to make it easier to understand the remaining features. This helps in focusing on specific details of a part without the distraction of other sections that might be unnecessary for that view.

Using break lines allows designers and engineers to present information more clearly while maintaining accuracy in depicting the geometry of the component. It’s important to note that break lines do not denote cut surfaces, hidden lines, or show dimensions but rather create a cleaner and more comprehensible representation of the components being depicted.
