MATSEC SEC Graphical Communication study plan

Set up a standard A3 drawing sheet with title block, border and first-angle projection symbol, using a T-square, 45°/60° set squares and H/2H/HB pencils.

Construct, from written descriptions only, the three principal views of six simple blocks, choosing correctly between first-angle and third-angle layout and labelling each view.

Apply line conventions deliberately: continuous thick outlines, dashed hidden detail, chain centre lines and thin dimension lines, on every drawing produced this week.

Dimension five of the six drawings to ISO 129 style - projection lines, arrowheads, gap from outline, no duplicated or crossed dimensions - then self-mark against a written checklist.

Convert five given sets of orthographic views into isometric drawings on 30° axes, keeping all isometric lines parallel to the axes and scaling lengths on the isometric scale.

Convert five isometric drawings back into three-view orthographic layouts, resolving ambiguous edges by adding hidden detail rather than guessing.

Draw isometric circles on all three faces of a cube using the four-centre method, then check each ellipse against a template or compass setting.

Produce one cabinet oblique and one cavalier oblique drawing of the same object, showing half-depth and full-depth receding axes at 45° respectively.

Construct isometric drawings of three curved solids (cylinder, cone, hemisphere) using ellipses built from the four-centre method, not freehand curves.

Handle non-isometric lines correctly by locating their endpoints from the orthographic views before joining them, demonstrated on two objects with sloping faces.

Complete four timed pictorial exercises at 20 minutes each, allocating time for layout, construction lines and final inking.

Compare cavalier and cabinet oblique for suitability on three given shapes and state in writing which projection you would choose and why.

Draw the front view, sectional plan and true shape of section for three solids cut by an inclined plane - a prism, a pyramid and a cylinder - projecting the true shape by auxiliary view or rotation.

Apply correct section hatching: evenly spaced thin lines at 45°, consistent spacing, no hatching across voids or on cut thin sections.

Locate the cutting-plane line with its arrowheads and lettering so that the direction of sight matches the section drawn.

Produce a frustum of a cone and a truncated hexagonal prism, checking that every visible edge in the sectional view corresponds to a point projected from the plan.

Develop the lateral surface of a truncated cylinder and a truncated cone using the parallel-line and radial-line methods respectively, with the seam line chosen deliberately and stated.

Develop a right pyramid and an oblique transition piece by triangulation, numbering each edge so that the development can be folded and checked mentally.

Draw the development of a cylinder intersected by a smaller cylinder at 90°, transferring each intersection point from the elevation onto the development.

Fold one paper development to confirm the layout closes correctly, and record in writing where the layout was wrong before folding.

Construct perpendiculars, angle bisectors, parallel lines and divide a line into any number of equal parts using compass and straight edge only, with construction arcs left visible.

Draw regular polygons of 5, 6, 7 and 8 sides both by the general method and by the specific method, and state in writing which is faster and which is more accurate.

Construct internal and external tangents between two circles, and an arc of given radius tangential to two lines, marking all tangent points.

Plot loci accurately: the locus of a point on a circle rolling along a straight line (cycloid), a point on a rolling circle (involute of a circle) and a point on a crank-and-connecting-rod mechanism, tabulating at least 12 positions per locus.

Produce freehand sketches of five objects using the crating method - light box first, then proportion check, then firm outlines - with no ruler used for the object itself.

Apply a three-level line-weight hierarchy in ink on one presentation drawing and annotate the drawing with leaders, notes and a title block.

Lay out a one-sheet design presentation: orthographic views, a pictorial view, dimensions, notes and title block arranged so nothing overlaps and the sheet reads left to right.

Sketch, from memory and in under 10 minutes, the standard symbols and conventions for first-angle and third-angle projection, centre lines, break lines, section hatching and a dimensioned hole.

Complete two full timed mock papers of 2 hours 30 minutes each, covering at least one question from every domain, under exam conditions with no notes.

Mark both papers against the official-style mark allocation per question, recording marks lost by cause (projection error, missing hidden detail, poor hatching, unfinished construction).

Re-draw the three questions that lost the most marks, correcting only the specific faults identified, and compare the two versions side by side.

Write a one-page exam strategy: question order, time per question, kit checklist and the three personal errors most likely to recur.
