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*.

Objectives
| Class 10.2: |
Sectioning in Design Drawings |
|
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 |
|
Use revolutions and partial views
as conventional practices to construct sectional views of an
object |
|
List the parts of a drawing which
do not get crosshatched, even if the cutting plane passes through
them |
|
Sketch a cutting plane for any
of the sections listed above |
|
know the steps required to become
a professional engineer |
| Class 26.1: |

to allow interior viewing |
|
Crosshatch interior surfaces of
a solid either before of after it has been cut open |

solid objects |

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.
