8 weeks · About 7 hours per week
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.
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.
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.
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.
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.
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.
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.
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.
