    Geometrical solidsGeometrical solids have 3-dimensions - length, width and depth. 
    Wire-frame drawingsGeometrical shapes and solids can be used to make wire-frame drawings. Simple shapes are built up to show a more complex object. This is also known as crating. 
    Surface developmentsA surface development or net is a shape cut from sheet material to make a 3D form. Developments can be used for any 3D shape. 
    Enhancement techniquesEnhancement techniques make a drawing look more like the real object. The technique used will depend on the type of drawing. 
    TextureTextures can be drawn to show different materials such as the grain on pieces of wood or reflected light on glass or plastics. Textures can be represented in shades of grey or colour. They give an impression of the material rather than representing it exa 
    Complimentary coloursComplementary colours are opposite on the colour wheel, for example, blue and orange. Complimentary colours contrast strongly with each other and make elements stand out. 
    Harmonious coloursHarmonious colours are next to each other on the colour wheel, for example, green, yellow and orange. They make a unified colour scheme. 
    Sequence diagramsSequence diagrams show the process of making something in words and pictures. They are useful if you need to tell someone else how to do a job or how to use something. 
    Perspective drawingPerspective drawings make objects appear more realistic, as they appear to recede as they get further away. If the receding lines are extended they will meet at points that are called vanishing points. 
    Section drawingsSection or cross section drawings show a product as if it has been sliced in half. The imaginary cut is called a section plane which is sometimes represented by a line consisting of long and short dashes.

    PlastazoteClosed cell cross-linked polyethylene foam. 
    InnovationA new ​idea or ​method. 
    Design problemA designer will construct a design problem in response to a specific situation which requires a solution. 
    CorroflutePolypropylene corrugated board. 
    FoamexFoamex is a PVC board which is rigid and durable whilst still being lightweight and flexible. 
    RenderingRendering is the process of adding shading, colour and lamination to a 2-D or 3-D wireframe in order to create life-like images on a screen or paper. 
    Mill boardA thick gauge card which is suitable for use in a variety of applications such as 3D design, back drops or mounting. 
    Safety rulerA ruler that has steeply bevelled edges on both sides and a deep central channel to provide protection for your fingers when cutting material with a craft knife. 
    PolypropyleneA ​type of ​plastic used for many ​purposes, such as ​food​packaging, making ​ropes, and making ​artificial ​fabrics. 
    Foam BoardA ​type of very ​light ​board made of a ​plastic ​substance ​full of ​small ​bubbles, often used to ​attach ​documents to in ​order to ​display them.

    Environmentally friendlyEnvironment-friendly, eco-friendly, nature-friendly, and green are marketing terms referring to goods and services, laws, guidelines and policies that inflict reduced, minimal, or no harm upon ecosystems or the environment. 
    Schematic drawingsA schematic drawing, or schematic diagram, is a representation of the elements of a system using abstract, graphic symbols rather than realistic pictures. 
    ErgonomicErgonomics, also known as comfort design, functional design, and user-friendly systems, is the practice of designing products, systems or processes to take proper account of the interaction between them and the people who use them. 
    Opaque​Preventing ​light from ​travelling through, and ​therefore not ​transparent or translucent

    HacksawA hacksaw is a fine-toothed saw, originally and principally for cutting metal. 
    Junior hacksawA junior hacksaw is a fine-toothed saw, originally and principally for cutting metal but 1/2 the size of the hacksaw. Blades can be narrow for more intricate work. 
    Centre punchA centre punch is used to mark the centre of a point. It is usually used to mark the centre of a hole when drilling holes. A drill has the tendency to "wander" if it does not start in a recess. A centre punch forms a large enough dimple to "guide" the tip 
    ScriberA scriber is a hand tool used in metalworking to mark lines on work pieces, prior to machining. The process of using a scriber is called scribing and is just part of the process of marking out. It is used instead of pencils or ink lines, because the marks 
    FileA file is a metalworking, woodworking and plastic working tool used to cut fine amounts of material from a work piece. It most commonly refers to the hand tool style, which takes the form of a steel bar with a case hardened surface and a series of sharp,  
    Tin snipsTinner's snips, also known as tinner snips or tin snips, are one of the most popular type of snips. They are defined by their long handles and short blades. 
    Ball peen hammerA ball-peen (also spelled ball-pein) hammer, also known as a machinist's hammer, is a type of peening hammer used in metalworking. It is distinguished from a cross-peen hammer, diagonal-peen hammer, point-peen hammer, or chisel-peen hammer by having a hem 
    Emery clothEmery cloth is a type of coated abrasive that has emery glued to a cloth backing. It is used for hand metalworking. 
    Wire woolSteel wool, also known as wire wool or wire sponge, is a bundle of very fine and flexible sharp-edged steel filaments. 
    PlanishPlannishing is a metalworking technique that involves finishing the surface by finely shaping and smoothing sheet metal with decoration.
