Design communication techniques in HSC Textiles and Design Design
“The communication techniques used to record and present design ideas, including illustration, technical drawing, computer aided design, sample boards and presentation, and how each supports the development and justification of a textile item”
Designers communicate ideas through freehand illustration and design sketches, technical or working drawings with measurements and construction detail, computer aided design for fast accurate variations, mood and concept boards that capture inspiration and palette, and sample or storyboards that present resolved ideas. Each technique records thinking, lets ideas be tested and refined, and justifies decisions to a client, marker or manufacturer.

What this dot point is asking
You need to explain the ways a designer records, develops and presents design ideas, and why communication is a working tool rather than just decoration. NESA wants you to describe the main techniques, illustration, technical drawing, computer aided design, mood and sample boards, and presentation, and to show how each helps generate, refine and justify decisions. The same techniques fill the supporting documentation of the Major Textiles Project, so this knowledge is examined and applied at once.
Illustration and design sketching
Design illustration is quick freehand drawing used to generate and explore ideas early in the process. Fashion croquis, flats and rendered sketches let a designer try many silhouettes, proportions and surface treatments without committing materials. Illustration captures mood and movement and shows how a fabric might drape or a colour might read. Because it is fast and loose, it suits the devising stage, where the goal is volume and variety of ideas rather than precision. Annotated sketches that note fabric, colour and reasoning are far more useful than a pretty picture with no explanation.
Technical and working drawings
Technical drawings, also called flats or working drawings, communicate the precise construction of an item to whoever will make it. They show the garment or product flat, to scale, with seams, darts, fastenings, topstitching, measurements and labelling of components. Unlike illustration, technical drawings are about accuracy and instruction, not mood. They allow a pattern to be cut and the item to be assembled correctly, and they let a marker or manufacturer see exactly what is intended. A complete documentation set usually pairs an expressive illustration with a clear technical drawing.
Computer aided design
Computer aided design lets a designer create, vary and test ideas digitally. CAD software produces accurate technical drawings, generates repeats for prints, recolours a design instantly to trial colourways, and simulates how a fabric or pattern will look on a body or product. It speeds up experimentation, reduces waste because trials are virtual, and produces professional presentation output. CAD also links design to manufacture through digital printing and computer controlled cutting and knitting, connecting this area to technology in the industry study.
Mood, concept and sample boards
Boards collect and present the thinking behind a design. A mood or concept board gathers inspiration, images, colour palette, textures and references that capture the intended feel and target market. A sample or fabric board presents trialled fabrics, colourways, surface treatments and construction samples so options can be compared against the design criteria. Storyboards present a resolved range or the development journey in sequence. Boards are powerful in the Major Textiles Project because they show, at a glance, that decisions were informed and deliberate rather than arbitrary.
Presentation and justifying decisions
The final purpose of communication is justification: persuading a client, marker or manufacturer that the design is resolved and the decisions are sound. Clear presentation organises illustrations, technical drawings, boards and annotations so the reasoning is easy to follow. Annotation is the connective tissue: each image is labelled with what was chosen, why, and how it meets the criteria. In the project documentation, communication that links every decision to the end use, target market and design criteria earns far more credit than visual polish on its own.
Bringing it together
In the exam, match the technique to its purpose: illustration for generating ideas, technical drawings for accurate construction, CAD for fast accurate variation and manufacture, boards for inspiration and comparison, and presentation for justification. In your own project, use a range of techniques and annotate everything, so the documentation reads as a clear, justified record of how the design developed.
You are documenting a new cushion design for your Major Textiles Project and must show a clear, justified development trail. Sequence the communication techniques.
Step 1: Capture the concept with a mood board
Build a mood board of inspiration images, the colour palette and reference textures to fix the intended feel and target market before drawing anything.
Step 2: Generate ideas with annotated illustration
Sketch several freehand design options, annotating each with the fabric, colour and reasoning, so the range of ideas and your thinking are both recorded.
Step 3: Compare options on a sample board
Trial fabrics, colourways and surface treatments and present them on a sample board, comparing each against the design criteria to select the resolved option.
Step 4: Specify construction with a technical drawing or CAD
Produce an accurate flat or CAD working drawing showing seams, measurements and finishes, then present everything with annotation that justifies each decision against the end use and criteria.
Design communication is a working tool, not decoration. Illustration generates ideas, technical drawings instruct construction, CAD speeds accurate variation and links to manufacture, and boards capture inspiration and compare samples. Annotation that links each choice to the design criteria and end use is what turns communication into justification.
Do not treat presentation as merely making the documentation look attractive. Unlabelled sketches and boards with no reasoning earn little. Markers reward annotated communication that explains what was chosen and why, and they expect technical drawings to be accurate and detailed, not just decorative illustrations.
Exam-style questions
Questions in the style of NESA exam questions on this dot point, each with a worked answer. They are written by ExamExplained unless tagged "Past paper"; the year shows the paper a question is modelled on.
HSC 2023-style3 marksOutline how a designer uses technical drawings and computer aided design to communicate and develop a textile item.Show worked answer →
Three marks: outline the role of BOTH technical drawings and CAD in communicating and developing the item.
Technical drawings (flats or working drawings) show the item flat and to scale with seams, darts, fastenings and measurements, communicating the precise construction so a pattern can be cut and the item assembled correctly.
CAD produces accurate technical drawings quickly, generates print repeats, recolours instantly to trial colourways, and simulates how fabric will look, speeding development and reducing waste because trials are virtual. CAD also links to manufacture through digital printing and computer-controlled cutting.
Full marks outline both techniques and their role in communicating and developing the design. Describing only one sits lower.
HSC 2024-style5 marksExplain how a range of communication techniques supports the development and justification of a textile item in the design process.Show worked answer →
Five marks: explain a range of techniques and link them to development AND justification.
Illustration and design sketching generate and explore many ideas quickly at the devising stage, capturing mood, drape and colour.
Mood and sample boards collect inspiration, palette and trialled fabrics so options can be compared against the design criteria.
Technical drawings and CAD record the resolved construction accurately for making and for variation.
Presentation and annotation justify decisions: each image is labelled with what was chosen, why, and how it meets the criteria, persuading a client or marker that the design is resolved.
Top band explains a range of techniques and ties them to both developing and justifying the item. Listing techniques without the development or justification link sits lower.
