Short Review: Sectional Views (Read First)
A sectional view is used to show the inside of an object that cannot be clearly shown using standard orthographic views. It is created by imagining a cut through the object and removing part of it to reveal internal features.
A cutting plane line shows where the imaginary cut is made and the direction the section is viewed. It is drawn as a thick, broken line with arrows and labeled (such as A–A).
In the sectional view, section lines (hatching) show the surfaces that were cut by the cutting plane. Object lines show visible edges, and centerlines locate holes or symmetrical features. Hidden lines are usually not shown in section views because the interior is already visible.
Section views make drawings clearer and help communicate internal details accurately.
