Maharashtra HSC Engineering Drawing (Technical Science) study plan

Set up a drawing board, T-square, set squares (45° and 30°–60°), compass, divider, and French curves, then draw five practice sheets of parallel horizontals, verticals, and 15°/30°/45°/60°/75° lines to build hand control

Construct perpendiculars, bisectors, and division of a line into n equal parts using only compass and set square, completing at least ten constructions on one A3 sheet

Project a point in all four quadrants and state its distances from HP and VP for each case, drawing ten point-projection problems with correct quadrant notation

Project a line parallel to HP, parallel to VP, and inclined to one plane, drawing front view and top view for eight given data sets and verifying true length by the rotating-line method

Write a one-page reference card listing the quadrant conventions, first-angle vs third-angle symbol, and the rule for locating front view above or below XY

Project lines inclined to both HP and VP using the auxiliary-plane (change-of-position) method, solving six problems where true length and true inclinations are found without rotating the line

Determine true shape of a plane surface inclined to one reference plane by the auxiliary-plane method, drawing four triangle and four pentagon/hexagon lamina problems

Construct regular polygons (pentagon, hexagon, octagon) by the general method and by the inscribed/circumscribed circle method, and inscribe a circle in a given triangle

Draw tangents to circles from an external point and construct an internal common tangent between two circles of unequal diameter

Solve five problems on a lamina inclined to both HP and VP, marking apparent inclinations α and β clearly

Draw projections of a prism, pyramid, cylinder, and cone in simple positions (axis perpendicular to HP and to VP), completing two problems for each solid

Project solids with axis inclined to one reference plane using the change-of-position method, solving six problems including a cone resting on its generator

Draw the three standard views of a solid resting on an edge or on a corner of its base, verifying that the base appears as an edge in the view where the solid is tilted

Construct true shape of the cut face for a solid cut by a plane perpendicular to VP and inclined to HP, solving four section problems

Prepare a one-page table of the number of visible and hidden edges for each standard solid in each position

Develop the lateral surface of a prism, cylinder, pyramid, and cone by the parallel-line and radial-line methods, drawing four developments with the seam line marked

Develop a truncated cylinder and a truncated cone, adding the true shape of the cut face to the development, for three problems

Construct the curve of intersection between two cylinders of unequal diameter intersecting at 90°, using at least eight generator points

Construct the intersection of a cylinder and a cone, and of a square prism and a cylinder, marking the curve in both views

State the difference between development by triangulation and by radial lines, and apply triangulation to one oblique transition piece

Construct isometric scale and draw isometric views of a cube, a rectangular block with a step, and a cylinder, keeping all isometric lines at 30° to the horizontal

Convert a given set of three orthographic views into an isometric view for five machine blocks, using the box method and non-isometric lines drawn by offsets

Draw an oblique projection (cavalier and cabinet) of a bracket and a stepped block, applying half-scale on the receding axis for cabinet projection

Produce full-sectional and half-sectional views of a stepped shaft and a bearing bracket, applying the correct hatching conventions (spacing, direction, no hatching on shafts and ribs cut longitudinally)

Draw a removed section and a revolved section for a ribbed casting, and label cutting-plane lines with arrows and section letters

Draw the conventional representation of ISO metric, BSW, and square threads in both elevation and end view, showing crest, root, and thread depth conventions

Draw a hexagonal bolt with nut and washer, a stud with nut, and a cap screw, dimensioning thread designation, length, and nominal diameter

Draw a protected-type and a saddle-key joint, and a gib-head key, showing the taper and the clearance in the keyway

Draw a flanged coupling (protected type) with six bolts and a bush-pin flexible coupling, half-sectioned, with a parts list

Draw a solid journal bearing and a bush bearing in half section, and label the journal, bush, cap, and lubricating hole

Define basic size, actual size, limits, tolerance, allowance, and deviation, and compute upper and lower limits for ten given shaft/hole pairs

Identify hole-basis and shaft-basis systems and classify fits as clearance, interference, or transition from given limits, working through fifteen numerical examples

Read and write ISO fit designations such as 50 H7/g6 and 25 H8/f7, and determine the type of fit from the letter and number

Draw the tolerance-zone diagram for six fits, showing the zero line, hole zone, and shaft zone with maximum and minimum clearance or interference marked

Interpret surface finish symbols for roughness values Ra, machining method, and lay direction, and apply the correct symbol to five given surfaces on a component sketch

Summarise lettering, line types, and sheet layout standards (title block, border, scale) in a one-page revision sheet

Draw the plan, elevation, and section of a single-room residential building with a 3 m × 4 m room, 230 mm walls, and a door and two windows, at a scale of 1:50

Draw the line plan of a two-room residential unit with a verandah, marking wall thickness, door and window positions, and room labels

Draw the detailed sectional elevation of a load-bearing wall showing foundation footing, plinth, damp-proof course, lintel, and roof slab with hatching conventions for brick, concrete, and earth

Prepare a schedule of doors and windows for the drawn plan, listing size, type, and number

Take a full-length timed mock exam of three hours covering one problem each from projections, development, isometric, machine drawing, and building drawing, then grade it against the marking scheme
