What conventions are asscoiated with section lines?

Section lines are typically used in architectural and engineering drawings to indicate where a cut has been made through a structure to reveal internal details. They are often represented as evenly spaced parallel lines, usually at a 45-degree angle, and may vary in thickness to convey different meanings. Additionally, section lines are labeled with letters or numbers to correspond to specific section views, helping to clarify which part of the drawing is being referenced. The spacing and angle of these lines can also adhere to certain standards, depending on the drawing conventions used.
