Projections

What is the definition of orthographic projection?

• Viewing multiple faces of an object at once

• Viewing one face of an object at a time

• Viewing an object from a 3D perspective

• Viewing an object from a single point

Which type of projection is always used in engineering drawings?

• Isometric projection

• Oblique projection

• Orthographic projection

• Pictorial projection

What is the main disadvantage of the orthographic drawing system?

• It is too expensive.

• It is difficult to understand by persons who are not trained in its usage.

• It is not accurate.

• It is too slow.

Why were isometric and oblique projections formed?

• To reduce costs.

• To improve accuracy.

• To easily communicate ideas to anybody.

• To speed up the process.

Which pictorial projection system presents the more natural looking view of an object?

• Orthographic projection

• Perspective projection

• Isometric projection

• Oblique projection

What type of projection shows a 3-dimensional view of an object?

• Orthographic

• Side view

• Isometric projection

In the orthographic projection, which view shows the object from above?

• Plan view

• Front view

• Side view

• Isometric

What does isometric projection involve?

• Viewing one face of an object at a time

• Viewing two faces of an object at a time

• Viewing three faces of an object at a time

• Viewing four faces of an object at a time

What becomes the starting point in isometric projection?

• The center of the object

• One corner of the object
