Maharashtra SSC Engineering Drawing ITI study plan

Maharashtra SSC Engineering Drawing ITI · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Orthographic Projection & Lines, Lettering and Dimensioning

  • Set up a drawing board with sheet sizes A4 to A0 and draft a title block that matches the standard layout used in ITI assignments.

  • Draw and label the full line-type family (continuous thick, continuous thin, dashed, chain thin, chain thick) and state two correct uses for each.

  • Construct a 45-degree and a 30/60-degree set-square lettering exercise, writing capital letters and numerals to the correct stroke order and height ratio.

  • Apply aligned dimensioning to a simple stepped block, including extension lines, arrowheads, leader lines and the three standard dimension-placement rules.

Your checkpoint

One A3 practice sheet containing the title block, a labelled line-type chart, a lettering block and a fully dimensioned stepped block, self-checked against a written checklist of 15 line and dimension rules.

Week 2

Orthographic Projection & Geometrical Constructions

  • Explain first-angle and third-angle projection and draw the symbol for each in the correct orientation.

  • Project a simple L-shaped block in first angle as front view, top view and side view, keeping heights, widths and depths aligned.

  • Bisect a line and an arc, drop and erect perpendiculars, and divide a line into any number of equal parts using the parallel-line method.

  • Construct regular polygons (pentagon, hexagon, octagon) by both the general method and the inscribed-circle method.

Your checkpoint

A single sheet with the two projection symbols, a complete three-view first-angle drawing of the L-block on squared layout, and four polygon constructions with construction arcs left visible.

Week 3

Orthographic Projection & Geometrical Constructions

  • Draw a circle through three given points and construct tangents to a circle from an external point.

  • Construct an ellipse by the concentric-circle method and a parabola by the rectangle method, labelling foci and directrix.

  • Convert a given multi-view drawing into a dimensioned drawing, deciding which dimensions belong on which view.

  • Identify hidden edges in a given object and represent them with correct dashed-line practice.

Your checkpoint

Two construction sheets: one with circle/tangent/ellipse/parabola constructions, one with a multi-view drawing where all hidden lines and dimensions have been added and justified in a short written note.

Week 4

Projection of Points, Lines and Planes & Orthographic Projection

  • Plot the projections of a point in all four quadrants and state its distance from HP and VP in each case.

  • Project a line parallel to one plane and inclined to the other, then a line inclined to both planes, using the auxiliary-plane and locus method.

  • Project a plane surface (triangle, square, pentagon) perpendicular to one plane and inclined to the other.

  • Check every solved problem by verifying that the true length and true inclination appear where the theory predicts.

Your checkpoint

A problem set of six solved projection problems (two points, two lines, two planes) with construction lines retained and a one-line verification note under each.

Week 5

Projection of Solids & Sections and Sectional Views

  • Project a prism and a pyramid resting on HP on a base edge and on a corner, keeping the axis correctly inclined.

  • Project a cylinder and a cone in the three standard resting positions.

  • Cut a prism and a cylinder with a section plane perpendicular to VP and inclined to HP, and draw the true shape of the section.

  • Hatch a sectional view at the correct angle and spacing and label the cutting-plane line with its arrows and letters.

Your checkpoint

A sheet with four solids (prism, pyramid, cylinder, cone) fully projected, plus two sectional views with true-shape auxiliaries and correct hatching.

Week 6

Development of Surfaces & Isometric and Oblique Projections

  • Develop the lateral surface of a right prism, cylinder, pyramid and cone by the radial-line and parallel-line methods.

  • Develop a truncated cylinder and a truncated cone, transferring cut points from the elevation to the development.

  • Construct an isometric scale and draw an isometric view of a simple block with non-isometric lines handled correctly.

  • Draw an oblique cavalier and cabinet projection of the same block and state the difference in scale factor and angle.

Your checkpoint

One development sheet with two truncated-solid developments and one isometric-plus-oblique sheet of the same object, drawn to a stated isometric scale.

Week 7

Limits, Fits and Tolerances & Fasteners, Keys, Couplings and Bearings

  • Define basic size, actual size, limits, deviation, fundamental deviation, tolerance and allowance and compute them for a stated shaft and hole pair.

  • Read and interpret hole-basis and shaft-basis designations such as H7/g6 and calculate maximum and minimum clearance or interference.

  • Sketch the three types of fit (clearance, transition, interference) on a tolerance-zone diagram with the zero line marked.

  • Draw a hexagonal bolt, nut and washer assembly and a square key in its keyway, with proportions taken from the nominal diameter.

Your checkpoint

A tolerance worksheet with five computed fits (values tabulated and classified) plus one neat assembly sketch of a bolted joint and one of a keyed shaft.

Week 8

Freehand Sketching and Reading of Drawings & Drawing Instruments, Materials and Standards & Limits, Fits and Tolerances

  • Produce freehand sketches of a bracket, a bearing and a pulley from written descriptions, keeping proportion without instruments.

  • Read a given assembly drawing and list its parts, then sketch the disassembled components freehand.

  • Recall instrument-care and material facts: pencil grades, drawing-board care, sheet sizes, scale types and standard line widths.

  • Revise the whole syllabus by re-solving one representative problem from each of the twelve domains under timed conditions.

Your checkpoint

A timed 90-minute mock paper covering all twelve domains plus a freehand sketch set, scored against an answer key with a written list of the three weakest areas to revisit.

Milestones

Week 2: Can draw the first-angle and third-angle symbols from memory and produce a correct three-view drawing of an unfamiliar simple block within 20 minutes without referring to notes.

Week 4: Solves a line inclined to both HP and VP completely, showing true length and both true inclinations, in under 15 minutes with construction lines that another person could follow.

Week 6: Develops a truncated cone accurately and draws an isometric view of a stepped block to a correctly constructed isometric scale, with a self-check score of at least 8 out of 10 on a rubric covering accuracy, line quality and labelling.

Week 8: Scores at least 60 percent on the timed 90-minute mock paper spanning all twelve domains, with no domain scoring zero.
