A Godot 4 C# plugin for building structures directly in the 3D scene editor.

Features:
- Floors: draw rectangles of tiles by click-and-drag (single MeshInstance3D per room)
- Walls: click two points to place a wall; L/T/X intersections resolved automatically with mitre joints
- Doors & Windows: click any wall to carve a real cutout in geometry and collision
- Stairs: two-click placement, step height calculated automatically per floor
- Roofs: flat, shed, gable, and hip types with configurable pitch
- Fences / Railings: modular, axis-aligned, driven by a PackedScene asset
- Multiple floors: per-floor visibility in the editor
- Bake: exports the building as an optimised .tscn with LOD0, LOD1, Occluder, and Collision
