# 3D New Era AI

> An open-source architecture and interior design editor with a Model Context
> Protocol (MCP) server built in. An AI agent draws walls, doors and windows,
> furnishes rooms, builds joinery, checks lighting and ergonomics against
> standards, and renders photos and videos — on the user's own computer, in
> centimeters, with undo. Free, MIT or Apache 2.0, for Windows, macOS and Linux.

3D New Era AI is a desktop program (Rust, ~30 MB, no account, no cloud). Opening
it starts an MCP server on `http://127.0.0.1:7878/mcp`, bound to loopback, so any
MCP client — Claude Code, Claude Desktop, Codex, Gemini CLI, Cursor, VS Code,
Windsurf, Cline, Cherry Studio — edits the same project the person has on screen.
Every call is a document command: it shows up in the window immediately and is
undone with Ctrl+Z. The interface speaks Portuguese, English, Spanish and French.

## What an agent can do over MCP

- Draw and modify walls, rooms, doors, windows, dimensions, texts and polylines,
  in centimeters, on any storey of the project.
- Place furniture from a 128-piece catalog with real sizes, and import 3D models
  (glTF, OBJ, Sweet Home 3D libraries).
- Build joinery that a workshop can make: cabinets, slatted panels, wardrobes and
  countertops with sink and cooktop cutouts, with cut lists in CSV and DXF.
- Lay out electrical, telecom and plumbing projects: points, circuits, a load
  schedule checked against NBR 5410, runs routed along walls and slabs with their
  bill of materials.
- Check lighting by photometry against NBR ISO/CIE 8995-1, and ergonomics and
  accessibility against NBR 9050 and NBR 15575 — each finding with the fix ready.
- Render: floor plans as PDF, SVG and PNG, elevations, sections, aerial views,
  path-traced photos and walkthrough videos, all on the CPU when there is no GPU.
- Read the project back: dimensions, areas, quantities, bills of materials.

## Install

- Windows: `irm https://raw.githubusercontent.com/leandrodaf/3d-new-era-ai/main/scripts/install-windows.ps1 | iex`
- macOS: `curl -fsSL https://raw.githubusercontent.com/leandrodaf/3d-new-era-ai/main/scripts/install-macos.sh | bash`
- Linux: download `newera-linux-x64.tar.gz` from the releases page and run `./newera/newera`

The Windows and macOS installers register the MCP server with Claude Code and
Codex when they are installed. For other clients:
`claude mcp add --transport http newera http://127.0.0.1:7878/mcp`
