Study Notes
Section View Representation of Rib, Web, Spoke, and Lug
- Ribs and webs are thin, flat structural features of an object.
- Spoke is a rod extending from a hub to the rim of a wheel.
- Lug is an ear-like feature designed for attachment.
Conventional Practice in Section View
- Rib, Web, and Lug: Omit section lines when the cutting plane passes flatwise through these features.
- Spoke: Omit section lines when the cutting plane passes lengthwise through.
Aligned Section
- An aligned section view is created by rotating the object's features about a symmetry axis to show the features in a principal view.
- This rotation is often used to clarify features that would otherwise appear in an unsymmetrical arrangement in a normal section view.
Conventional Break
- Conventional breaks are used to shorten long objects in drawings to save space.
- This involves removing a portion of the object that contains no critical information and drawing break lines at the ends of the removed section.
