What is the main advantage of oblique drawings?

1. They require multiple views for clear understanding

2. They utilize existing orthographic plans for easier modifications

3. They provide the most accurate 3D representation

4. They are always created at a 90-degree angle to the viewer

The correct answer is: They utilize existing orthographic plans for easier modifications

Oblique drawings offer a significant advantage in their ability to effectively utilize existing two-dimensional orthographic plans, allowing for more straightforward modifications and enhancements to the design representation. This capability makes oblique drawings particularly useful in design when needing to present three-dimensional visuals derived from existing plans without starting from scratch. In this format, the third dimension is represented while remaining aligned with the original plan, enabling designers to communicate changes and concepts more fluidly. This is particularly beneficial in fields like interior design, architecture, and engineering, where modifications are common, and visual clarity is essential. While other options may seem relevant, they do not capture the unique practical utility of oblique drawings as clearly as how they enhance and modify existing plans.
