Where is cross hatching typically added in a cross section view?

In a cross section view, cross hatching is primarily added to the areas that have been cut through. This technique visually distinguishes the internal structure or material from the exterior of the object being represented. By applying cross hatching within the cut areas, it allows viewers to easily identify the different materials used or the specific features present in the cross section. This means that when examining the drawing, the cross-hatched areas provide essential information about the inner components, facilitating a clearer understanding of the object’s overall design and structure.

The other areas of the drawing, such as the edges, background, or parts above the section line, don't serve the same purpose of conveying internal information, which is why they are generally not hatching. In practical applications, utilizing cross hatching correctly enhances the clarity and effectiveness of technical drawings.
