Sectional Views
When are Sectional Views Covered?
Sectional Views are introduced in ENGR111 during Class 10.2*
Sectional Views in AutoCAD are revisited in ENGR112 during Class 26.1*.

List and recognize the hatching symbols for Cast Iron, Steel, Aluminum, Copper, and Zinc |
|
Identify a drawing as being a: full section, half section, offset section, broken-out section, revolved section, or removed section |
| |
Generate the above mentioned sectional views given complete orthographic views of an object |
|

Why are Sectional Views Important?
Sectional Views are important because they describe the internal details of a part that may not always be clear when the part is drawn in orthographic views. As a result, manufactures require an imaginary cross-sectional cut through a drawing of a part to clarify the interior parts.
