Hatching Lines:
Hatching lines, also known as section lines, are used in engineering drawings to represent the internal structure of an object that has been cut and viewed in a sectional view.
These lines are drawn at an angle (commonly 45°) and are spaced evenly to indicate the material of the object.
Purpose:
Hatching lines are essential for showing the internal features and materials of an object after it is sectioned.
