GUIDANCE: IT IS VITALLY IMPORTANT YOU PERFECT YOUR SKETCHING SKILLS TO PREPARE YOURSELF FOR COMPLETING NOT ONLY THE MAJOR PROJECT BUT PAPER 1 AND PAPER 3
THIRD ANGLE PROJECTION
FIRST ANGLE PROJECTION
ONE POINT PERSPECTIVE
One point perspective is a drawing method that shows how things appear to get smaller as they get further away, converging towards a single 'vanishing point' on the horizon line. It is a way of drawing objects upon a flat piece of paper (or other drawing surface) so that they look three-dimensional and realistic.
TWO POINT PERSPECTIVE
(It is a) linear perspective in which parallel lines along the width and depth of an object are represented as meeting at two separate points on the horizon that are 90 degrees apart as measured from the common intersection of the lines of projection.
ISOMETRIC
Isometric drawing is way of presenting designs/drawings in three dimensions. In order for a design to appear three dimensional, a 30 degree angle is applied to its sides. The cube opposite, has been drawn in isometric projection.
OBLIQUE
An oblique drawing is a simple form of three-dimensional (3D) drawing that is often created for drafting or engineering. Such a drawing usually consists of an object in which the front of the object is drawn flat, with the height and width of the object drawn the proper lengths. The object is then given depth through sides drawn at an angle to create the sense of the object being three-dimensional; this is often at a 45° angle and the sides can be foreshortened.
EXPLODED
An exploded view is commonly used for assembly drawings to show the relationship between different components and how they fit together. It helps understand the order of assembly of the different parts

T SQUARE / PARALLEL MOTION BAR and DRAWING BOARD
A T-square (USED INSTEAD OF A PARALLEL MOTION BAR) is a technical drawing instrument used by draftsmen primarily as a guide for drawing horizontal lines on a drafting table. The instrument is named after its resemblance to the letter T, with a long shaft called the "blade" and a short shaft called the "stock" or "head".
PENCILS
The core of every drawing pencil contains a mixture of graphite — a type of carbon — and a binder. Pencils containing more graphite are softer and produce darker marks, while pencils containing more binder are harder and produce lighter marks. Most manufacturers indicate the hardness of a pencil’s graphite with a number and/or letter. This is known as the HB scale.
In this scale, the letter “H” is used to indicate hardness while the letter “B” indicates blackness. “F” designates that a pencil sharpens to a fine point. The higher the number next to the “B”, the softer the pencil is. Likewise, the higher the number next to the “H”, the harder the pencil is. In general, a standard writing pencil is equivalent to an HB hardness.
