Glossary

In rough order of how often each term appears.

Generation

A chat turn that builds a model from scratch. Costs 30 credits. Typically the first turn in a project, or any later turn where the agent decides to rewrite the model from scratch.

Iteration

A chat turn that refines an existing model. Costs 15 credits. The cheap, fast iteration loop.

Continuation

A multi-step round inside one chat turn (e.g. the agent takes a screenshot, then interprets it, then makes an edit — all in one user message). Free. You won't typically notice it as a separate event.

Parameter

An adjustable knob the agent declared as part of the model. Surfaces as a slider, button group, or switch in the bottom-right of the viewport. Free to drag — the model re-renders locally with the new value. See Parameters.

Section

A named group inside a model — the outer carcass, the shelves, the plinth, etc. The agent uses sections to organize its work and to give itself a referrable handle ("the Carcass section"). See Sections.

Primitive

A single shape inside a section. The agent assembles primitives to build up the larger pieces — a panel here, a leg there, a moulding profile somewhere else. You rarely think about primitives directly; the count of them in a model is shown in the viewport's bottom-left chip as a rough complexity gauge.

Plan

The agent's interpretation of your prompt before it builds — dimensions, layout, style direction. Appears as a Plan Review Panel in chat with an Approve button. See Chat-driven design.

Checkpoint

A snapshot of the model at one point in time. Auto-checkpoints fire on every successful build; manual checkpoints (pinned, named) survive past the auto-retention limit of 20. Local-only — they don't sync to the cloud. See Iterating.

Project

One design conversation: chat history, current geometry, parameters, checkpoints, renders. Each project is independent; the agent does not cross-reference projects. See Projects.

File

A sub-design inside a project. Lets you keep two variants in one shared chat context.

Render

A photorealistic image of the current viewport view, produced by a heavier offline pipeline. Costs 50 credits. Different from a PNG export (which is what the viewport already shows). See Views and screenshots.

Material slot

A named entry in the model's material palette (main, hardware, counter, accent, etc.). Each slot is filled by a curated library entry — and any primitive tagged with that slot's name picks up the look. See Materials and style.

Material library

The curated set of PBR materials (woods, metals, stones, fabrics, paints) the agent can pull from when picking a finish.

Action

A single step the agent takes inside one chat turn — changing the model, taking a screenshot, adjusting the camera, and so on. Each action surfaces in the chat as its own labelled card, which you can expand to see what happened.

CSG (boolean operations)

Constructive Solid Geometry — combining shapes via union, intersection, or subtraction. The agent uses CSG to carve recesses, drill holes, and produce the kind of geometry that primitives alone can't express. CSG results are baked into the export.

PBR

Physically-Based Rendering. The material model used by the viewport and by GLB/OBJ exports — color, roughness, metalness, plus optional clearcoat, transmission, anisotropy, etc.

STEP / DXF / OBJ / GLB / DAE / STL / PNG

Export formats — see Exporting overview and the per-format pages.

Credit

The unit of in-app currency. 1 credit = 1 US cent at top-up. See Credits.

Free trial

The 120 credits you get on first sign-in. Covers about four full generations.

Top-up

A one-off Stripe purchase that adds credits to your balance. Minimum $10 = 1,000 credits. Also unlocks CAD / 3D exports permanently. See Top-up.

Paywall (export gate)

The dialog that appears the first time an unpaid user clicks a CAD or 3D export. Closes for life once you top up at least once.
