2. Engineering Graphics IV Section Views Auxiliary Views Dimensioning Tolerancing

3. Section Views

4. Clearly show interior features Avoid confusing hidden lines

5. Cutting Planes Cutting planes define section views Lines of sight are perpendicular to the cutting plane Section views are parallel to cutting plane and perpendicular to lines of sight Objects shown in true size Cut surface is cross- hatched

8. Cutting Plane Lines Show where cutting plane passes through object Represent edge view of cutting plane Appear in views adjacent to section view

9. Full Section

10. Half Section

11. Offset Section

12. Broken Out Section

13. Sketch Section View

14. Solution E-drawing

15. Sketch Section View

16. Solution

17. Cross Hatching (Section Lines) General symbol (cast iron) used for most purposes and for sketching Section lines are normally drawn at 45° from the horizontal but can be changed for adjacent parts in the same section Normally section lines are not shown on thin parts Components like bolts are usually not sectioned

18. A)Cast Iron/ B) Sound C) Thermal General Insulation Insulation D) Water E) Steel F) Titanium/ Refractory Material G) Concrete H) Wood (across/along grain)
