Week 4

What is the main purpose of a sectional view in technical drawing?

• To add decorative details to the drawing

• To reduce the number of dimensions required

• To show internal features that are not visible in standard views

• To create a 3D effect

Which type of sectional view shows the entire object as if it were cut completely in half?

• Offset Section

• Full Section

• Broken-Out Section

• Revolved Section

What do section lines (hatching) in a sectional view represent?

• Hidden edges

• The material that has been cut through

• The external surface of the part

• The outline of the object

In which sectional view is only one half of the object cut, while the other half remains in its original state?

• Offset Section

• Full Section

• Half Section

• Removed Section

The number of views in a technical drawing should always be as many as possible to avoid missing details

• True

• False

A one-view drawing is typically used for simple objects like cylinders or cones when all details can be seen in a single view.

• True

• False

Hidden lines are represented by dashed lines in technical drawings.

• True

• False

A complex object has multiple holes, channels, and internal cavities. How should it be best represented in a technical drawing?

• Using hidden lines to indicate all internal features

• Using multiple sectional views to eliminate hidden lines

• Using an oblique projection to combine internal and external features

• Using an isometric view only, since it shows three sides at once

You are reviewing a technical drawing of a casted metal part that features drilled holes and internal slots. The drawing includes multiple hidden lines, making it look cluttered and hard to read. What is the best way to improve clarity?

• Use sectional views instead of hidden lines

• Increase the spacing between the hidden lines

• Use an exploded view to separate parts

A thin metal plate has a single hole at its center. Which set of views is sufficient to fully define it?

• Front and top views

• Front, top, and right-side views

• Isometric and top views

• One sectional view only
