## What it is
Realtime-CSG is a Unity editor plugin providing constructive solid geometry (CSG) level design tools, letting developers build levels non-destructively from additive, subtractive, and intersecting brushes. It generates meshes and collision automatically in real time during editing, with no runtime editing support.

## Use cases
- build game levels in Unity with CSG brushes
- prototype level geometry quickly without manual mesh modeling
- cut holes in walls for doors and windows non-destructively
- auto-generate collision meshes for level geometry
- blockout levels for FPS or 3D games

## When to choose
- you design or prototype 3D levels in Unity and want fast, non-destructive iteration
- you want Quake-style brush-based level editing inside the Unity editor
- you need automatic collision mesh generation from level geometry

## When to avoid
- you need runtime CSG editing or a runtime API
- you want to boolean-modify arbitrary existing meshes rather than CSG brushes
- you target Linux or ARM platforms, which are unsupported or incomplete
- you need the native C++ source code
