Final answer:
Orthographic drawings are preferred over pictorials due to their accuracy, ease of creation and understanding, precise measurements and dimensions, and widespread use in engineering and technical fields.
Step-by-step explanation:
Orthographic drawings are preferred over pictorials such as isometric or oblique sketches for several reasons:
- Accuracy: Orthographic drawings provide a more accurate representation of the object compared to pictorials. They show the object from multiple views, giving a clear and precise view of its shape and dimensions.
- Ease of creation and understanding: Orthographic drawings are easier to create and understand as they follow standardized conventions for projection, making them less prone to errors.
- Precise measurements and dimensions: Orthographic drawings allow for precise measurements and dimensions as each view is drawn separately and can be dimensioned accurately.
- Commonly used in engineering and technical fields: Orthographic drawings are widely used in engineering and technical fields because of their accuracy, clarity, and ease of understanding.
