Deck 27: Half Sections, Partial Sections, and Full Section Assembly Drawings

Question 1

Describe a half-section view.

Answer 1

In a half-section view, one-half of the object is drawn in section and the other half is drawn as an exterior view. The half section is used principally where both the inside and outside details are symmetrical and where a full section would omit some important details in an exterior view.

Question 2

Explain when a broken or partial section is used.

Answer 2

On some parts, it is not necessary to use either a full or a half section to expose the interior details. In such cases, a broken-out or partial section may be used. The cutting plane is imagined as being passed through a portion of the object, and the part in front of the plane is then broken away. The break line is an irregular freehand line that separates the internal sectioned view and the external view.
