MATSEC IM Engineering Drawing and Graphical Communication study plan
MATSEC IM Engineering Drawing and Graphical Communication · Give each week a clear focus.
8 weeks · About 6 hours per week
Orthographic projection and multi-view drawing & Drawing standards, conventions and graphical literacy
Set up a drawing station with A3 board, T-square or parallel rule, 2H/HB pencils, compass, and set squares, and calibrate linework so that construction, visible, hidden, and centre lines are visibly distinct in weight and dash pattern
Draw a title block and border to a stated sheet size and complete five multi-view exercises that convert a given 3D object into front, plan, and end views using first-angle projection consistently
Apply the first-angle versus third-angle symbol correctly and explain in writing why Maltese and European practice defaults to first-angle
Produce a one-page convention sheet listing line types, their weights, and at least eight permitted abbreviations used on engineering drawings
Your checkpoint
A folder of five fully drawn A3 multi-view sheets (first-angle, correct line hierarchy, completed title blocks) plus the one-page convention sheet
Orthographic projection and multi-view drawing & Geometric construction and plane geometry
Construct accurate multi-view drawings of objects containing inclined faces, cylindrical features, and stepped profiles, choosing the minimum number of views needed to define the form
Perform plane-geometry constructions from scratch: bisecting angles and lines, erecting and dropping perpendiculars, dividing a line into equal parts, and constructing regular polygons by both general and specific methods
Construct tangents between circles and to circles from external points, and draw a smooth tangent arc blending a line and a circle
Read a set of three given views and produce the missing third view by projection rather than by guessing
Your checkpoint
One A3 construction portfolio sheet containing at least ten labelled geometric constructions, plus two completed missing-view exercises
Pictorial drawing and 3D representation & Geometric construction and plane geometry
Draw isometric projections of blocky and cylindrical objects using the 30-degree axes and isometric scale, keeping all three axes true to length
Produce oblique cavalier and cabinet drawings and state when each is preferable to isometric
Construct one-point and two-point perspective views of a simple component or small structure using vanishing points and a horizon line
Convert an isometric sketch back into orthographic views and check dimensional consistency between the two representations
Construct ellipses in isometric planes using the four-centre approximate method and verify against an isometric circle template
Your checkpoint
One A2 or two A3 pictorial sheets: one isometric, one oblique, and one perspective drawing of the same object, with the matching orthographic views alongside for comparison
Geometric construction and plane geometry & Dimensioning, tolerancing and annotation
Construct true shapes of inclined surfaces and develop the lateral surface of a truncated cone and a square-to-round transition piece
Apply dimensioning rules: no duplicated dimensions, dimensions placed outside the view where possible, leaders terminating on the feature, and consistent arrowheads and gaps
Add limit dimensions with hole and shaft tolerance notation, and interpret at least five tolerance callouts correctly
Annotate surface finish symbols, weld symbols, and thread designations on an existing drawing without contradicting the geometry
Your checkpoint
A dimensioned and toleranced A3 drawing of a machined bracket, marked against a self-made checklist of twenty dimensioning rules, with a written correction log
Sections, auxiliary views and developments & Orthographic projection and multi-view drawing
Produce full sections, half sections, and offset sections of a component, applying correct hatching direction, spacing, and the rule that ribs and webs are not hatched when cut longitudinally
Draw a revolved section and a removed section and label each with the correct cutting-plane line and arrows
Construct an auxiliary view from an inclined face so that the face appears true shape, projecting correctly from the primary views
Develop the pattern for a truncated pyramid and a cylinder intersecting a plane, and check the developed length against calculated values
Your checkpoint
An A3 sectional and auxiliary-view sheet for a single component showing a full section, an offset section, and one auxiliary view, plus one separate development pattern cut out and folded to verify fit
Engineering components and assembly drawing & Dimensioning, tolerancing and annotation
Identify and draw standard engineering components: hexagon-head bolts, nuts, washers, plain and rolling bearings, keys, pins, and compression springs, using simplified representations
Draw standard thread representations for external and internal threads in both section and end view, and specify thread callouts correctly
Read an assembly drawing and extract a parts list with item numbers, descriptions, quantities, and material
Produce a detailed drawing of one part taken from an assembly, adding dimensions and tolerances consistent with its function
Your checkpoint
A component library sheet of at least ten standard parts plus a detailed drawing of one part extracted from a supplied-style assembly, with a completed parts list
Graphical communication, charts and technical presentation & Drawing standards, conventions and graphical literacy
Construct a bar chart, a line graph with labelled axes and units, and a pie chart from a small data set, choosing the appropriate chart type and justifying the choice in two sentences each
Draw a simple schematic diagram using standard electrical or fluid-power symbols and produce the matching key
Draft a short technical report page integrating a drawing, a chart, a caption, and a numbered figure reference
Critique three drawings for graphical-communication weaknesses such as inconsistent lettering, poor layout, or ambiguous annotation, and rewrite the weakest one
Your checkpoint
A two-page technical presentation: one page of charts and schematic with key, one page of corrected drawing and written critique
Orthographic projection and multi-view drawing & Dimensioning, tolerancing and annotation & Sections, auxiliary views and developments
Complete two full timed mock papers under exam conditions, allocating time per question and finishing within the limit
Mark both mocks against a self-built rubric covering projection accuracy, line quality, dimensioning completeness, and section correctness, and list every recurring error
Redraw the three weakest answers from the mocks to full standard without reference to the original attempt
Compile a one-page personal error checklist and rehearse the drawing-kit setup and sheet layout routine so that it takes under five minutes
Your checkpoint
Two completed timed mock papers with marked rubrics, three redrawn answers, and a final one-page error checklist
Milestones
Week 2: Can produce a correct third view from two given views in under 15 minutes with no projection errors, and complete all ten geometric constructions without erasing construction lines
Week 4: Dimensioned bracket drawing passes at least 18 of 20 self-made dimensioning rules, and both developments match calculated lengths within 2 mm
Week 6: Assembly parts list is complete and the extracted part drawing carries every dimension needed to manufacture it, with no redundant dimensions
Week 8: Both timed mocks completed within the time limit, with the error checklist showing no repeated error from the week 4 or week 6 milestone reviews
