Sectional Drawing- Test Review

Part Drawings:
- Detail drawings completely describe a single part with multiview orthographic projections.
- Should provide all the informationnecessary to economically manufacture a high quality part.

Assembly Drawings:
- Assembly drawings are used to show the position and functional relationship of parts in an assembly, also via multiview orthographic projections

Section Views:
- Section views are used to clarify internal detail and to avoid dimensioning to hidden lines
- They are established by referencing a cutting plane

Crosshatch symbols:
- Cast iron ( General use )
- White metal ( Zinc )
- Sand
- Steel
- Magnesuim, Aluminum
- Titanium

Half Sections:
- Half section views are the result of cutting planes being positioned on parts in such a manner only half of the resulting view or projection is shown in section

Offset Sections:
- Offset sections allow us to provide greater breadth of detail with fewer section views. All of the features are aligned with the cutting plane.
