Diagram editor engine
Core2D
A complete foundation for technical drawing and diagramming.
Overview
A multi-platform, data-driven 2D diagram editor with a portable model, rendering backends, and extensible tooling.
Core2D is maintained as a focused part of a wider open-source .NET UI ecosystem. Its boundaries are designed so applications can adopt the useful layer without taking the entire stack.
