Break lines are thick lines with zigzag patterns used to show where an object is broken out to reveal a hidden detail or to simplify a complex drawing.
Center lines are long and short dash lines that indicate the center of an object or feature. They are used to locate the center of circles, arcs, and symmetrical objects.
Thin lines are lines used for minor details, edges, and dimensions in a drawing. They are typically used to differentiate between different parts of a drawing.
Construction lines are very lightly drawn lines used to layout the basic shape or size of an object before adding more detail. They are usually drawn in pencil and erased once the final drawing is completed.
Continuous thick lines are used to outline the main features of an object.
Continuous thin lines are used to represent objects that are not visible in the current view but are located behind the visible objects.
Cutting plane lines are used to indicate where an object has been cut in a sectional view.
Dimension lines are thin lines with arrows at both ends that indicate the measurements of an object.
Extension lines are thin lines used to show the limits of a dimension. They connect the dimension line to the object being measured.
