  1. Sectional Views

  2. Types of Sectional Views • Half • Full • Offset

  3. Half Section • In a half section, one quarter of the part is cut away. • The cutting plane line goes half-way through the object. • This is done with symmetrical parts where you would like to show the outside, as well as the inside details.

  4. Half Section

  5. Half Section Notice how the cutting plane line runs through the center of the part; there is no arrow head.

  6. Full Section • The cutting plane passes fully through the object. • In a full section, half of the object is cut away.

  7. Full Section

  8. Full Section A full section is a view that shows what the object looks like if it were cut in half.

  9. Full Section A cutting plane line is used to indicate how the front view was cut. It is also labeled in case another section is necessary. The arrows should point in the line of sight as you are looking straight on at the section.

  10. Full Section Section lines called Hatch lines are used to show where the part is solid. This helps to see the detail that would be normally blocked and only shown as hidden lines.

  11. Interior features not in line with each other can be shown in an offset section view. Note how the cutting plane line changes and follows the center of each feature. Offset Section
