Walls from lines (walls_from_lines): a home3dplan MCP tool

What it does

Turn imported lines into walls on a storey: double-line mode pairs parallel lines a wall apart into one wall at the measured thickness and makes an opening where both faces gap; centreline mode makes a wall on every line. Reads every line on a layer whose name says wall, or every layer when none does, or the given layers. The lines move to a hidden layer. One revision.

A write. It saves one revision of the project, which appears in the open editor at once and can be undone there. Scope: **projects:write**.

Inputs

**projectId** (string, required): See the tool’s description.

**storey** (integer): Default 0.

**mode** (double | centreline): Default double.

**thickness** (number): mm, for centreline walls and unpaired lines

**minThickness** (number): See the tool’s description.

**maxThickness** (number): See the tool’s description.

**layerNames** (string[]): See the tool’s description.

**unpairedAsWalls** (boolean): See the tool’s description.

**openingsFromGaps** (boolean): See the tool’s description.

What comes back

What changed, in words and in a structured form, and the link that opens the project in the editor on the right storey and view.

Tip: if the project changed in the editor between two calls, the write is refused as a conflict and the assistant opens the project again. Nothing is overwritten.

Ask for it like this

"Turn the imported wall lines into real walls."

The assistant chooses the tool and fills its inputs from what you said; you do not name the tool or type its inputs.
