Working in three dimensions: the main processes (modelling, carving, construction and casting), the demands of real form and space, and how to develop and document 3D work for AO2 and AO4.

What this dot point is asking

Working in three dimensions means making real form in real space, through modelling, carving, construction or casting. It demands a different kind of thinking from two-dimensional work, because a piece exists from every angle and must physically stand, balance or hang. This dot point is about how the main 3D processes work, the particular demands of real form, and how to develop and document 3D work so it earns AO2 (exploring and refining) and AO4 (a resolved outcome).

The demands of real form

The first thing to grasp about three-dimensional work is that it is not a drawing made solid; it is a different problem. A 3D piece exists from every angle, so it must be considered in the round, not just from the front. It also occupies real space and obeys gravity, so it must physically stand, balance or hang, and the material must be able to do what you ask. These demands (all-round form, real space, physical construction) shape every decision.

Additive and subtractive processes

The main processes divide by whether you add or remove material.

Material and construction

In three dimensions the material is part of the meaning, not just the means. A form in welded steel, carved wood, soft fabric or cast plaster says different things and behaves differently. Construction (how parts join, how the piece is supported and balanced) is both a practical necessity and an expressive choice. Strong 3D work chooses a material because it suits the idea and resolves the construction so the piece is stable and considered, which feeds both AO2 and AO4.

Documenting three-dimensional work

Because moderators usually see 3D work through photographs (and the object itself may not travel), documentation is critical. Photograph maquettes and trials, work in progress, and the resolved piece, each from several viewpoints and in clear, even light, with attention to background. Annotate the development as you would a 2D project. Good documentation lets the moderator see the form in the round, the development through maquettes, and the resolution, so the work earns the AO2 and AO4 marks it deserves.

Try this

Q1. Explain the difference between additive and subtractive 3D processes, with an example of each. [Knowledge recall]

• Cue. Additive builds form by adding material (modelling in clay, constructing from parts) and allows adjustment; subtractive removes material from a block (carving wood or stone) and demands commitment, since removed material cannot be replaced.

Q2. Explain why thorough photographic documentation is essential for three-dimensional work. [Short explanation]

• Cue. Moderators usually assess 3D work through photographs rather than the object itself, so documenting every stage and the resolved piece from several angles lets them see the form in the round, the maquette development and the resolution, securing the AO2 and AO4 marks.
