Orthographic projections are described as three-dimensional in the material. True or false?

• A. True
• B. False
• C. Not specified
• D. Depends on context

Answer: (A)

Orthographic projections are described as three-dimensional in the material because this method conveys the full three-dimensional form of an object through a set of two-dimensional views. Each view—front, top, and side—captures true dimensions along its own plane, so when you look at all the views together you can understand and measure the object's length, width, and height. In other words, while a single view is flat, the combination of views preserves the three dimensions and lets you reconstruct the 3D shape. If you focus on one view alone, it appears 2D, but the orthographic projection technique as a whole is about representing 3D objects through multiple 2D representations.
