Vexlio

Easily create precise and beautiful diagrams with automatic snapping, embedded LaTeX, and more. Much of the power of Vexlio is the robust automatic snapping system that forms its foundation. No more time spent making careful, tedious manual adjustments to ensure the objects in your diagrams are visually lined up. With Vexlio, lines, arrowheads, and other objects snap into perfect geometric alignment every time. Or, use the Lua programming interface if you prefer to draw your diagrams with code. Vexlio also provides a number of useful tools, such as native LaTeX equation editing and quick object duplication, that you will find indispensible for your technical diagrams. You can reuse your commonly used objects and shapes with the built-in Prefab Library. Vexlio also has a plugin system to allow you to add your own custom functionality or install plugins others have written.
