Process presentational and technical graphic designs

Requires students to produce at least two presentational graphics and two technical drawings.  They should include either charts generated automatically from numerical processing software or computer slide show presentations, and use both landscape and portrait orientations

1. describe graphic design software and give examples of how they might be used
2. identify the components of presentational graphics and technical drawings
3. produce presentational graphics according to design specifications
4. produce technical drawings according to design specifications
5. save and output graphic images

Graphic design software: bitmap. vector; chart, slide show presentation

Components: (straight, arc, curve, freehand), shapes (rectangular, circles, polygons), colour, shade, text (style, size), attributes (style, thickness, fill), brush, spray

Presentational graphics: slide show, chart, picture

Technical drawings: layout, product design, block schematic

Design specifications: graphic type (bitmap, vector), purpose, context (publicity, design layout, information presentation), content, dimensions (size, units, tolerances), image (width, height, colours, shades), page attributes (size, orientation, margins)

At least two presentational graphics anbd two technical drawings.  These must include the use of both bitmap and vector graphic software and include either charts generated automatically from numerical processing software or computer slide show presentations.  Both landscape and portrait orientation must be included.

Notes:

• describing in general terms all types of graphic design software in the range and giving one example of how each type might be used.
• identifying the components of presentational graphics and technical drawings.

Bitmap (PC1 range) an electronicgraphic file where each minute item (dot) in the graphic picture is represented by a single (or several for colour) bit of information in the file.  Elements of the bitmap graphic cannot be edited as an entity.

Vector (PC1 range) an electronic graphic file where the graphic elements are defined in vector form which enables them to be scaled each time they are used, without loss of resolution.  The entities (eg lines etc) in the graphic can be manipulated individually.

Presentational graphics (PC1 and PC3 range) graphic images which are used tp present artwork-type information such as pictures, or electronic artwork.  Such material is created or stored as a bitmap image.

Technical drawings (PC2 and PC4) graphic representations which are produced using vector based software such as layouts of buildings or car parks and detailed drawings of artefacts which are used for manufacture.

Chart (PC2 and PC3 range) refers to software for producing charts such as histograms and pie charts. Many graphics and spreadsheet packages provide such facilities.

Layout (PC2 and PC4 range) refers to the production of drawings, using vector-based software, which represent a plan view of the objects; examples include kitchens, house, car parks, road maps and railway maps.

Product design (PC2 and PC4 range) refers to the production of drawings, using vector-based drawing software, which defines how an artefact is to be manufactured: examples include telephone casing, table, cycle pedal, window frame or a tennis racket.  The drawings define size, materials, and thickness.

Block Schematic (PC2 and PC4 range) refers to the use of vector-based drawing software to produce graphic images to represent, in very simple terms,, any system, flow or organisation. Examples of block schematic diagrams could be a set of labelled boxes used to describe the operation of a control system, a set of boxes showing the functions of an organisation and depicting the flow of information, or an outline of a micro-processor with boxes representing the components.
