Section Views
Sectional views are used quite often when drawing assemblies. Assemblies often have parts fitting into or overlapping other parts and we need to look inside the assembly to see clearly.
Section Lines: Section lines in adjacent parts are drawn in opposing directions.
- In the largest area, section lines are drawn at 45°.
- Next largest = 135° (- 45°).
- Additional areas = 30° and 60°.
- Smaller areas = The distance between the section lines may also be varied to further distinguish between parts.
