Week 3

What does an orthographic projection show?

• A realistic 3D view of an object

• Multiple 2D views of an object at right angles

• A single view from an angle

• A view with converging lines

How many views are typically used to fully describe an object in a technical drawing?

• 1

• 2

• 3

• 4

When is a one-view drawing sufficient?

• When the object is complex and asymmetrical

• When the object is a flat or cylindrical part with uniform thickness

• When hidden details need to be shown

• When multiple angles are required to understand the part

Why is it important to limit the number of views in a technical drawing?

• To save paper

• To avoid confusion by only showing necessary views

• To create a more artistic drawing

• To make the drawing look complex and detailed

If a part has holes on both sides that align with each other internally, what should be done in the technical drawing?

• Only show one side view

• Provide both side views to display the alignment

• Omit side views altogether

• Use a perspective view instead

If an object has a slanted hole not visible from the front, top, or side views, how can it be shown accurately?

• Use a perspective view

• Ignore it if it’s not visible

• Add an auxiliary view

• Use hidden lines only

Which criterion is not considered when determining the number of views in technical drawings?

• The geometric shape of the part, its level of complexity.

• The condition of the details inside the part.

• The situation of the part in manufacturing conditions and the manufacturing method

• The quality level on the surface of the piece

You are drawing a technical sketch of a symmetrical bracket. The front view shows the height and width clearly, and the top view reveals the depth. The side view, however, looks identical to the front view due to the bracket's symmetry. What is the best approach?

• Keep all three views since it’s standard practice.

• Remove the side view since it adds no new information.
  

• Add an auxiliary view just in case.

• Draw extra views to emphasize the bracket's symmetry.

The front view should 

• Show the most visible features

• Be above the right view

• Be the view you like best
