Architects use Orthographic (e.g., Plan, Elevation, and Section Drawings), Axonometric, and Perspective Drawings to graphically describe their work. Of these drawing types, which are 3-dimensional?

A. Perspective only.
B. Axonometric and Perspective.
C. Axonometric and Orthographic.
D. Orthographics (Plan, Elevation, and Section) only.

Axonometric and Perspective Drawings are three-dimensional representations used in architecture, while Orthographic Drawings are two-dimensional. Orthographic Drawings include plan, elevation, and section views. Therefore, the correct answer is Axonometric and Perspective.

Explanation:

Understanding 3D Drawings in Architecture

In architectural design, different types of drawings are used to represent structures, including Orthographic, Axonometric, and Perspective Drawings. Out of these, Axonometric and Perspective Drawings are the types that provide a three-dimensional representation of objects.

Orthographic Drawings, such as plan and elevation drawings, portray objects in two dimensions. This includes:

Plan Drawings - Top views of a building.
Elevation Drawings - Side views showing height and materials.
Section Drawings - Cut-through views that display internal features.

On the other hand, Axonometric Drawings offer a way to viewed objects from an angle, allowing the viewer to see multiple sides simultaneously, while still maintaining parallel lines. Meanwhile, Perspective Drawings create a sense of depth and realism by depicting objects as they appear to the eye, converging lines towards a vanishing point.

Thus, the correct answer to the question of which types of drawings are three-dimensional is: Axonometric and Perspective.
