Question

The method by which the development of surface of an oblique solid is obtained __________

(a) radial line

(b) parallel line

(c) triangulation

(d) approximation

I had been asked this question in a job interview.

My doubt is from Development of Surfaces topic in chapter Development of Surfaces, Isometric Projections, Perspective Projections & Transformation of Projections of Civil Engineering Drawing

Answer 1

The correct answer is:

(c) triangulation

Explanation: In the context of developing the surface of an oblique solid, triangulation is the method used to break down the complex surface into smaller, simpler triangular sections. This approach helps in accurately unfolding the surface of the solid into a two-dimensional pattern for further construction or analysis.

• Radial line (a) and parallel line (b) are methods used in different types of projection techniques, but not specifically for developing the surface of oblique solids.
• Approximation (d) involves using estimated methods, which is generally less precise than triangulation in this context.

Thus, triangulation is the correct method used to develop the surface of an oblique solid.
