NCEA L1 DVC key terms

The subject where you use drawing, sketching, and digital tools to develop and present design ideas. It combines visual thinking with technical drawing conventions and design process knowledge.

Conveying information and ideas mainly through images, drawings, diagrams, and layout rather than words alone. Effective visual communication makes meaning clear to a chosen audience without extra explanation.

The staged way a designer moves from a brief to a resolved outcome, typically including research, ideation, development, refinement, and presentation. Each stage produces evidence of thinking that can be reviewed and improved.

A statement of the problem, needs, and constraints a designer must respond to. It names the intended user or client, the purpose of the outcome, and any limits such as size, cost, or materials.

The limits placed on a design, such as budget, size, materials, safety rules, or time. Good design decisions show awareness of these limits rather than ignoring them.

Measurable requirements a design must meet, written as clear statements or values. They allow a design to be tested objectively against the brief at the end of the project.

The people a design or drawing is made for, whose needs, knowledge, and expectations shape how information is presented. Audience affects choices like scale, colour, wording, and level of detail.

The stage of generating many possible ideas quickly before judging them. Techniques include brainstorming, sketching, and mind maps, and quantity at this stage often leads to better final solutions.

A design idea that carries a clear intention or theme and can be developed further. Concepts are usually explained with sketches plus short notes describing how they answer the brief.

The stage where promising ideas are changed, combined, and tested to improve them. Evidence includes annotated sketches showing what changed and why, rather than a single finished drawing.

Repeating a design step with changes based on feedback or testing. Each cycle should show a visible improvement or a reasoned rejection of an option.

Judging how well a design meets its brief and specifications, using evidence rather than opinion. It usually identifies strengths, weaknesses, and specific next steps for improvement.

Comments from users, clients, teachers, or peers used to improve a design. Useful feedback is specific and is recorded with the designer's response to it.

Short written notes placed next to a drawing to explain decisions, materials, function, or next steps. Annotations turn a picture into evidence of design thinking.

A very small, quick drawing used to explore many layout or form options cheaply. Thumbnails focus on overall shape and composition rather than fine detail.

A precise drawing that communicates shape, size, and construction using agreed conventions such as line types, views, and dimensions. It must be readable by someone who never saw the object.

A method of showing a three-dimensional object as separate flat views, usually front, top, and side, arranged in a fixed layout. Each view shows true shape for the faces parallel to it.

A standard arrangement of orthographic views where the top view sits above the front view and the right side view sits to the right. The symbol of a truncated cone identifies it on a drawing sheet.

The view of an object seen from directly above, showing its footprint and horizontal layout. In building drawings it is often the main view, showing walls, openings, and furniture positions.

A view of an object or building seen from the side or front, showing heights and vertical relationships. Elevations are usually drawn flat, without perspective, so measurements stay true.

A pictorial drawing on three axes spaced 120 degrees apart, with vertical edges drawn vertically and no vanishing points. It shows three faces at once but does not use true perspective.

A pictorial drawing where the front face is drawn true shape and depth is shown by lines going back at an angle, often 45 degrees. It suits objects with one important flat face.

Any drawing that shows an object in three dimensions on a flat sheet, such as isometric, oblique, or perspective. Pictorial views communicate overall form quickly to non-specialists.

A drawing system where parallel lines appear to converge at vanishing points, mimicking how the eye sees depth. One-point and two-point perspective are the common school versions.

The point on the horizon line where receding parallel lines appear to meet in a perspective drawing. All lines of the same direction share one vanishing point.

The horizontal line in a perspective drawing that represents the viewer's eye level. Its height changes whether we look down on, level with, or up at an object.

The ratio between a drawing and the real object, written like 1:50 or 1:100. Choosing a suitable scale lets a full design fit the sheet while staying measurable.

Adding measurements to a drawing using dimension lines, extension lines, and arrows or ticks, with units stated once. Correct dimensioning lets a maker build the object without guessing.

The agreed meanings of different lines, such as continuous for visible edges, dashed for hidden edges, and chain lines for centrelines. Consistent line types make technical drawings unambiguous.

Light guide lines drawn first to set up proportions, angles, or perspective before darker final lines are added. They are usually left faint or erased in a finished drawing.

Adding tone, colour, shading, or texture to a drawing to suggest materials, light, and three-dimensional form. Good rendering supports understanding of the design rather than hiding weak drawing.

Varying darkness on a drawing to show where light falls and how surfaces curve or face away. Consistent light direction across a set of drawings keeps them believable.

The choice and arrangement of type, including font, size, weight, spacing, and alignment. In design work it affects readability, hierarchy, and the overall character of a layout.

The arrangement of text, images, and white space on a page or screen. A strong layout guides the eye in a planned order and keeps related items grouped together.

Designing products and spaces to fit human body sizes, reach, strength, and comfort. Anthropometric data such as average heights and grip sizes inform these decisions.

The final arrangement of drawings, notes, and models that communicates a resolved design to an audience. Clear ordering, consistent style, and readable labels are as important as the drawings themselves.
