Composer sends Create, Enhance, and Edit messages. The active mode controls which inputs are required.

The control row contains the mode, model and output settings, image count, Keep prompt, and Send controls. Composer references attach inside the Composer card. The source image for Enhance or Edit lives in the right panel.

Each mode keeps its own prompt and Composer references. Switching modes does not clear the other drafts.

Create requires a prompt. Enhance can send without one. Edit requires one prompt after you mark a region. The Edit prompt must mention every unique region name outside quotes. Region names are references, not requested scene text.

After a successful send with Keep prompt off:

The active mode's prompt and Composer references clear.
An Enhance source clears.
An Edit source stays selected, but its mask and regions clear.
Drafts in the other modes stay unchanged.

Turn Keep prompt on to retain the active prompt, references, Enhance source, or Edit source, mask, and regions after a successful send. This preference is stored in the current browser.

If a render brief has a hard ambiguity, Composer temporarily shows one clarification question instead of its normal controls. Choose a suggested answer immediately, or write a custom reply and select Continue. Select Back to revise the previous answer. Press Escape to discard the clarification and restore the original draft.

Skip and Send Now renders the original prompt and keeps no clarification. Its tooltip says: “Skip these questions and render your original prompt. No clarification will be saved.” Provider or network failure follows the same original-prompt path silently.

A mode conflict is a confirmation instead of a question. Composer shows Review before sending. Select Back to composer to change modes, or select Continue with Create, Continue with Enhance, or Continue with Edit to send the original prompt under the selected mode's rules.

Public Help Center

Start in the prompt. Composer help is authoritative for the commands it lists. The article also documents field-save behavior.

Slash commands

Slash commands can update project settings without opening a settings tab. Type / in the prompt to open the current command list. Use lowercase commands at the start of the message.

/style sets the Style field.
/scene sets the Scene field.
/lighting sets the Lighting field.
/materials sets the Materials field.
/entourage sets the Entourage field.
/shortcuts opens Composer help.
/help opens the Help Center in a new tab.

Add the new value after a field command:

/lighting soft overcast daylight with long diffuse shadows
/materials pale oak, lime plaster, dark bronze frames

Keep the camera at eye level and the room quiet.

Leading field commands update the project before the render snapshot is taken. The remaining text becomes the render prompt.

You can also send field commands without a render prompt. CAD Scene updates the fields and adds an Undo event to the Feed. No render is generated or charged.

Commands are read only from the leading lines. The first normal or unknown line starts the prompt. If the same field appears more than once, the last value wins.

/shortcuts and /help are UI-only commands. When either appears among the leading command lines, CAD Scene opens its destination and removes that command line from the active draft. It does not submit a render. Any remaining prompt text, field commands, and Composer references stay in place for the next send.

Keyboard shortcuts

Use Cmd on macOS. Use Ctrl on Windows and Linux.

Press Cmd/Ctrl+? or use /shortcuts to open Composer help. The dialog is the authoritative reference for the Composer, workspace layout, mode, and slash commands it lists. Cmd/Ctrl+S is field-editor behavior and remains documented below.

Composer help keeps commands, mode keys, layout keys, and Help links together.

Composer

Cmd/Ctrl+Enter sends the active draft.
Shift+Enter inserts a newline.
In a custom clarification reply, Cmd/Ctrl+Enter selects Continue.
In clarification, Escape returns to the original Composer draft.

Workspace layout

Cmd/Ctrl+K focuses the Composer prompt.
Cmd/Ctrl+B toggles the studies rail.
Cmd/Ctrl+. toggles the settings rail.
Cmd/Ctrl+? opens Composer help.

Modes

Cmd/Ctrl+1 switches to Create.
Cmd/Ctrl+2 switches to Enhance.
Cmd/Ctrl+3 switches to Edit.

Project fields

Cmd/Ctrl+S saves the focused Composition field.

Global layout and mode shortcuts are suppressed while you type in an input. Composer send and newline shortcuts still work in the prompt.

Composer reference images

Select the attachment control to add visual context. Choose a render or upload from the picker, upload a new image, or attach the last render.

Composer references are separate from the Enhance or Edit source. They are also separate from the Project reference image.

Each mode keeps its own reference list. The list skips duplicates and accepts up to five images.

Reference support depends on model and mode. Every selectable model supports references in Create and Enhance. In Edit, GPT Image 2 uses only the source and mask. Switch to a Nano Banana model or remove the references.

See image roles for the complete comparison.
