How are centerlines and cutting planes typically drawn?

Centerlines and cutting planes are typically drawn using different line types to visually differentiate them from other elements on a drawing. Centerlines are usually represented with a long dash and short dash pattern or a continuous line with alternating long and short dashes, while cutting planes, which indicate where a section is taken through the object, use a different line style—often a thicker line or another specific pattern. This distinction is critical in technical drawings, as it allows the viewer to quickly interpret the drawing and understand the representation of the object in 2D space. Different line types ensure clarity and prevent misinterpretation of the drawing details, contributing to effective communication of information within architectural, engineering, and construction documents.
