What this dot point is asking
Three-dimensional work makes form in real space, and it uses a distinct family of processes and materials. This dot point is about the main processes (modelling, carving, construction, casting, assemblage), the materials available, the difference between additive and subtractive approaches, and the role of maquettes. Exploring three-dimensional work is strong AO2, and it brings in considerations (the round, structure, weight) that flat work does not.
Form in real space
The defining feature of three-dimensional work is that it exists as real form, occupying space and seen from every side. This changes how you design: a piece must work from all viewpoints, not just the front, and it must physically stand, balance and hold together. These considerations, the round, structure, weight and base, are particular to three-dimensional work and must be planned, often through maquettes.
Additive and subtractive processes
The processes divide by whether material is added or removed, and this difference shapes how you plan.
The materials
Three-dimensional work uses a wide range of materials, each suited to different processes and effects.
- Clay is modelled (and can be fired into ceramic); it is plastic, tactile and good for organic and figurative form.
- Plaster is cast (into moulds) or carved when set; it gives a solid, white, workable form.
- Card and paper are constructed (cut, scored, folded, joined); cheap and quick for testing structure and making maquettes.
- Wire is constructed into linear, open, drawing-in-space forms, and into armatures (internal supports).
- Wood, metal and plastics are carved, constructed and joined for more permanent work.
- Found objects are assembled, bringing their own associations and meanings.
Maquettes and planning
Because three-dimensional work is physical and often irreversible (you cannot un-carve or easily rebuild a fired pot), planning matters more than in flat work. The maquette is the central planning tool: a small, quick model that tests the form, composition, structure and viewpoints before you commit time and material. Maquettes are themselves strong AO2 evidence, showing the form developed in three dimensions.

Q1. Name the additive and subtractive three-dimensional processes, with an example of each. [Knowledge recall]
- Cue. Additive processes build material up: modelling (clay), construction (card, wire, wood) and assemblage (found objects); subtractive processes cut material away: carving (wood, stone, plaster, soap); plus casting (mould-making) as a separate process.
Q2. Explain the role of a maquette in three-dimensional work. [Short explanation]
- Cue. A maquette is a small-scale trial model made to test a form, composition, structure and viewpoints in three dimensions before committing to the full piece; it is the three-dimensional equivalent of a thumbnail or preparatory study and is especially important because three-dimensional work is physical and often irreversible.
Exam-style practice questions
Practice questions written in the style of WJEC Eduqas exam questions on this dot point, with worked answer explainers. The year tag is the paper they imitate, not the source.
Eduqas Component 1 AO212 marksComponent 1 Personal Investigation, AO2 and AO3. Explain how a candidate on the theme Growth would explore three-dimensional processes and materials, and what a moderator would reward.Show worked answer →
This rewards purposeful exploration of three-dimensional processes and materials matched to the idea, with maquettes and review, not a single object.
Matching process to idea. Growth (organic, branching, expanding forms) suits construction in wire and card for branching structures, modelling in clay for swelling organic forms, and assemblage of natural found materials; the candidate tests which conveys growth.
Exploring processes and materials. Building wire armatures and forms, modelling clay, making maquettes (small trial models) to test forms in the round, casting a form in plaster, assembling found organic objects; each tried and reviewed.
What a moderator rewards. A moderator rewards maquettes and tests that explore form in three dimensions (AO2), first-hand recording of three-dimensional sources informing them (AO3), review of which process and material suit growth, and a note of what to develop. A single object with no maquettes or exploration scores far less.
Eduqas Component 2 AO28 marksExplain the difference between additive and subtractive three-dimensional processes, with an example of each, and the role of a maquette.Show worked answer →
A short explanation needs the additive and subtractive contrast and the maquette's purpose.
Additive processes. Form is built up by adding material: modelling (building up clay), construction (joining card, wire, wood) and assemblage (combining found objects). Material is added to make the form.
Subtractive processes. Form is cut away from a solid block: carving (wood, stone, plaster, soap). Material is removed to reveal the form, and it cannot be put back.
The maquette. A maquette is a small-scale trial model made to test a form, composition and structure in three dimensions before committing to the full piece, the three-dimensional equivalent of a thumbnail or preparatory study.
Why it matters. The two approaches are opposite (build up versus cut away), affecting planning, especially as carving is irreversible. A strong answer names additive and subtractive examples and explains the maquette as a three-dimensional planning tool.
