Question

IS 15021: Part 2: 2001 is standard for _________________________

(a) axonometric representations

(b) orthographic representations

(c) di-metric representations

(d) isometric representations

I had been asked this question in an international level competition.

My question is based upon BIS Code of Practice in division Loci of Points & Orthographic Projections of Engineering Drawing

Answer 1

Right choice is (b) orthographic representations

To explain I would say: IS 15021: Part 2: 2001 is standard for Orthographic representations. IS 11065: Part 2: 1985 is standard for Di-metric projection. IS 11065: Part 1: 1984 is standard for Isometric projection.
