Answer:
1. A half section exposes the interior of one half of an object while retaining the exterior of the other half.
2. A revolved section shows the shape of an object by rotating a section 90 degrees to face the viewer. The three revolved sections illustrated in the spear-like object of figure 12 show the changes that take place in its shape.
3. A removed section is a section or partial section not directly projected from the view containing the cutting plane and not revolved or turned from its normal orientation. A removed section does not align with any other view, but, sometimes appears on centerlines extended from the section cuts.
4. Assembly section is a presentation of a structure or product with its components connected together, in their relative working positions while in use.
5. This is the most common section (called a full section) with the imaginary laser cutting a line across the entire construction, offering a view of a portion of the building with the rest of it put to one side.
6. A broken-out section view cuts away a portion of an assembly in a drawing view to expose the inside. Cross hatching is automatically generated on the sectioned faces of all components. A broken-out section is part of an existing drawing view, not a separate view.
7. An offset section is a means of including in a single section several features of an object that are not in a straight line. To do this, the cutting plane line is bent, or “OFFSET” to pass through the features of the part.
8. Section lines are special lines placed on a drawing which indicate the area of the drawing through which an imaginary cut has been made to reveal internal details.
9. Cutting plane lines are thick lines that run through the center of the object that the interior wants to provide an interior view of. Two perpendicular lines with arrows showing in which direction the interior of the object should be viewed are drawn at the end of the line
10. A sectional view represents the part of an object remaining after a portion is assumed to have been cut and removed. The exposed cut surface is then indicated by section lines. Hidden features behind the cutting plane are omitted, unless required for dimensioning or for definition of the part.
