Architectural Draftsman Grade II PWD 2023 — Kerala PSC PYQ Practice with Answers

Correct answer (Option D):\nDdashed lines, or hidden lines, are specifically used in engineering and architectural drafting to signify edges, surfaces, or intersections of an object that are hidden from the viewer's current line of sight. Standard drawing practices regulate these patterns to maintain clarity across technical documentation. Option D is correct.\n\nWhy others are wrong:\nOption A is used to indicate axes of symmetry or centers of circular components. Option B marks the limits of a dimension line. Option C displays the measurement extent and values.\n\nStudy tip:\nFamiliarize yourself with the standard hierarchy of lines specified by Bureau of Indian Standards (BIS) or ISO guidelines for technical drawing.

Correct answer (Option B):\nThe accurate perception and translation of light and shadow is a foundational requirement in sketching to create depth, three-dimensional form, and realistic values on a flat surface. Without understanding tonal values, sketches appear flat and lack structural realism. Option B is correct.\n\nWhy others are wrong:\nOption A is too vague as a fundamental skill framework. Options C and D refer to specialized geometric and mathematical drawing projection methods rather than basic freehand sketching skills.\n\nStudy tip:\nWhen studying architectural rendering, practice continuous value scales from pure white to absolute black to master shadow mapping.

Correct answer (Option D):\nIn the standard pencil grading scale, 'H' denotes hardness and 'B' denotes blackness or softness. The higher the number preceding the 'B', the softer the graphite core and the darker the mark it leaves. Therefore, 6B is significantly softer than 4B, 2H, and 6H. Option D is correct.\n\nWhy others are wrong:\nOptions A and C represent hard pencils used for clean engineering layouts. Option B is a soft pencil but has less graphite softness compared to 6B.\n\nStudy tip:\nRemember the sequence of pencil grades: 9H (hardest) down to HB (medium), and up to 9B (softest and darkest).

Correct answer (Option A):\nNeutral colors are purely functional tones that lack high-intensity chroma or a definitive position on the vibrant color wheel. Black, white, grey, and occasionally brown or beige serve as neutral structural backdrops in design and art composition. Option A is correct.\n\nWhy others are wrong:\nOption B is a primary warm color. Option C is a primary cool color. Option D is a secondary cool color derived from mixing yellow and blue.\n\nStudy tip:\nIn architectural interiors, neutral colors are widely selected for major surface areas to let accent colors create intentional focus areas.

Correct answer (Option B):\nAccording to standard engineering lettering and drafting recommendations (such as IS 9609 / ISO 3098), the height of the main titles on standard-sized drawing sheets ranges between 6 mm and 12 mm to ensure high legibility and proper layout hierarchy. Option B is correct.\n\nWhy others are wrong:\nOption A is too small for main titles and is generally used for minor annotations or dimensions. Options C and D are given in centimeters, which are far too large for standard architectural sheets.\n\nStudy tip:\nStandard lettering heights are typically organized in a geometric progression, such as 2.5 mm, 3.5 mm, 5 mm, 7 mm, 10 mm, and 14 mm.
