Script Window

Build scenes without MCP by pasting a DSL script into an editor window.

The Script Window takes a DSL script and applies it to the scene. It works without any MCP package installed.

Open it from Window > UModeler X > AI Shape Script (Window).

Workflow

Press Copy Prompt. The full syntax guide is copied to the clipboard.
Paste it into ChatGPT, Claude or similar, and describe what you want. (For example: "Build a two-seat bench.")
Copy the AI's reply and press Paste in the window, or paste it into the text area directly.
Press Validate to see errors first. (The scene is not changed.)
Press Run to build the objects in the currently open scene.

Button	Action
Copy Prompt	Copy the syntax guide for the AI to the clipboard.
Paste	Paste the clipboard contents into the text area.
Clear	Empty the text area.
Validate	Check the script without changing the scene.
Run	Run the script in the currently open scene.

The guide produced by Copy Prompt carries:

Output rules — reply with the script only, no code fences and no explanation
Scene conventions — meters and degrees, Y is up, +X is right, +Z is forward
Pivot convention — most shapes have their pivot at the center of the bottom face, so a shape of height h occupies y to y+h and the next part stacked on top goes to @0,h,0. Ring-like kinds such as Torus are centered on the pivot instead.
The full syntax table — the same syntax definition the MCP tool carries
An example script — a bench assembly

After a run, a summary and a detail list appear at the bottom of the window.

Created / updated / deleted objects — in "Name#id" form
Number of modifiers added
Failed nodes — with line numbers and reasons
Warnings — duplicate names, shape parameters given to a non-parametric target, and so on

Each list is capped at 30 items so the panel does not grow unbounded.

Message	Cause
`Indentation must be in 2-space units.`	Indentation is not a multiple of two spaces, or tabs were used.
`Indentation depth increased by more than one level at once.`	The line indented more than one level deeper.
`Unknown kind '...'`	No such shape type. Check the allowed list in the message.
`Unknown key '...'`	No such parameter name.
`Unknown modifier '...'`	No such modifier.
`Target not found: '...'`	The reference or delete target is not in the scene.
`Editor is compiling. Retry after compilation completes.`	Compilation is in progress. Run again when it finishes.
