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*.

*Explaination of Class numbering System


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: Editing Solids in AutoCAD
  Create planar secitons through solids
  Cut solid models open to allow interior viewing
Crosshatch interior surfaces of a solid either before of after it has been cut open
  Apply fillets and chamfers to 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.
