Layout of the Paper

Section A: 15 short questions, attempt all questions but you are marked out of best 10.

Section B: 6 long questions, marked out of best 4. Make sure to do at least 4.

35 mins per question for higher level, exam is 3hours long

30 mins per question for ordinary level, exam is 2 and half hours long.

There is no need to put a border on the sheet.

Make sure you put your exam number and not your name on every sheet you hand up.

Remember there are marks going in every question for neatness and accuracy.

Make sure your sets are fully equiped before the exam.

Question 1

Orthographic Projection - Generally have to draw an elevation, plan and end elevation. Plan is always below the elevation. Put end elevation on correct side-looking at the left; see it on the right on your sheet. Make sure to include the hidden detail and to insert the four dimensions.

Question 2

Ellipses - Draw the ellipse using the major and minor circles and then divide it up 60/30. If equal parts are shown then the line has to be divided up into the equal parts(line at an angle, step off parts on your compass, join last back to end of the line and go parallel). If your given 3 points on a curve, join two and bisect, join other two and bisect, where bisectors meet is the centre point.

Question 3

Developments - Draw the elevation, plan and end elevation of the given figure (Only draw what is asked, sometimes not all three are asked for). Do the development separately. Development is where the object is folded out flat. Broken lines are shown wherever there is a fold.

Question 4

Do either Oblique or Isometric

Oblique is where you draw the elevation and come back 45° off it for the depth. Isometric is started by using the crows foot, 30°, 30° and straight up.

Question 5

Transformation Geometry - Remember to label all the points first and read the question to find the correct order and from which points. Translation – Distance and angle, image will looked the same but will have moved position. Axial symmetry - 90° to axial line and rotate points from the line, image will be a mirror of the object. Central symmetry – all the lines go through the central point and rotate around from that point, image will be upside down and back to front.

Question 6

Circles in Contact – Draw what is shown in the question. Circles that touch internally, you take away the radius, circles that touch externally you add the radius. Show all points of contact if asked to in the question.

Short Questions

Main things to watch out for:

Finishing off orthographic – Project lines between the views to finish

Freehand sketching – Reasonable sized sketch, not tiny. Add shade to sketch.

Perspective – Lines have to be vanished to two vanishing points, should look like the given 3D

CAD commands – Learn the command from the hand-out

Scale - Using the given scale to give the measure of the length asked for

Shadow/Shade - Projecting the shadow onto the wall

Area - Give the area by counting all the full squares and all the half squares in given figure

Ellipses - Tangents to ellipses, finding focal points

Area Conversion – Triangle to rectangle, Rectangle to square, Rectangle to triangle

Circles in Contact – Join the centres to get Points of contact; don’t forget ones between circle and line

Developments – Where shape is opened out flat
