Maharashtra SSC Engineering Drawing ITI study guide
Maharashtra SSC Engineering Drawing ITI · Work through your exam, one topic at a time.
Engineering Drawing is a core trade-theory subject in the Maharashtra ITI (Industrial Training Institute) system, examined under the State Council of Examinations umbrella for SSC-level vocational candidates. It is aimed at trainees in draughtsman, fitter, machinist, welder and allied engineering trades who must read, interpret and produce technical drawings to shop-floor standards. The Maharashtra SSC Engineering Drawing ITI study guide has 13 sections and about 3,848 words.
01Drawing Instruments, Materials and Standards
This domain tests the drawing office itself: the instruments you choose, the sheet you work on, the scale you use and the BIS/ISO conventions that make a drawing readable. Standard sheet sizes (IS 696 / ISO 216): A0 1189 × 841 mm, A1 841 × 594, A2 594 × 420, A3 420 × 297, A4 297 × 210, A5 210 × 148.
305 words, about 2 min02Lines, Lettering and Dimensioning
This domain tests whether you can select the correct line, letter a drawing legibly, and dimension it without ambiguity. Visible outlines: continuous thick.
332 words, about 2 min03Geometrical Constructions
Geometrical construction questions test compass-and-straightedge accuracy and the ability to set out polygons, curves and tangents from given data. Bisect a line or angle with compass arcs of radius greater than half.
303 words, about 2 min04Orthographic Projection
Orthographic projection is the core of the paper: converting a described or sketched object into aligned front, top and side views in first angle. The object is placed between the observer and the plane.
302 words, about 2 min05Projection of Points, Lines and Planes
This domain tests the geometry of points, straight lines and planes in space and their two-dimensional projections. A point is located by its distance above or below HP and in front of or behind VP.
370 words, about 2 min06Projection of Solids
Questions here test whether you can project prisms, pyramids, cylinders and cones in simple and tilted positions. Prisms, pyramids, cylinders and cones are drawn from their base and axis.
282 words, about 1 min07Sections and Sectional Views
Sectioning questions test your ability to cut an object, show the interior clearly and hatch only solid material. A cutting plane is shown by a chain thick line with arrows at the ends; the arrows point in the viewing direction and the plane is labelled A–A.
283 words, about 1 min08Development of Surfaces
Development questions test whether you can unroll a solid surface to a flat sheet without stretching it. Parallel-line development is used for prisms and cylinders: stretch the perimeter along a line and set off the true height.
257 words, about 1 min09Isometric and Oblique Projections
This domain tests pictorial drawing: isometric and oblique views that show three faces of an object in one picture. Isometric axes are 120° apart, drawn at 30° to the horizontal.
266 words, about 1 min10Limits, Fits and Tolerances
This domain tests the language of interchangeable manufacture: limits, deviations, tolerances and the fit selected for a hole and shaft. Basic size is the nominal size; actual size is measured.
266 words, about 1 min11Fasteners
Fastener questions test thread conventions and the approximate proportions used to draw bolts, nuts, rivets and joints. Metric threads have a 60° included angle and are designated M followed by the nominal major diameter, e.g.
292 words, about 1 min12Keys, Couplings and Bearings
This domain covers the machine elements that connect shafts and support them: keys, couplings and bearings. A sunk key fits into keyways in both shaft and hub and transmits torque by shear and crushing.
283 words, about 1 min13Freehand Sketching and Reading of Drawings
This domain tests quick, proportioned freehand work and the reverse skill of reading orthographic views to visualise the object. Hold the pencil lightly and move the whole arm.
