Smart Polygons in Flux behave intuitively like traces, making them straightforward to learn and use—start directly from any pad with automatic net association, simply click to place and adjust points, and watch as copper intelligently reflows in real-time. Let’s dive in!
In PCB design, polygons are customizable copper shapes directly tied to a specific net. They’re crucial because they significantly influence the electrical performance and reliability of your PCB. Polygons allow you to optimize your board layout for specific electrical properties, including improved grounding, controlled impedance, and efficient heat distribution.
Specifically, polygons are indispensable for:
Unlike zones—which define areas where copper cannot exist—polygons actively conduct electricity and shape your board's electrical performance, making them fundamental for advanced PCB designs.
At Flux, we prioritize intuitive, user-friendly workflows. Automatic copper fills were the first step. Now with polygons, we've continued this approach:
Polygons in Flux behave intuitively like traces, making them straightforward to learn and use, right from the start.

With the latest release of Copilot it isn’t just smarter—it’s hands-on, placing components and applying bulk changes to your project instantly. But to get the most out of it, knowing how to craft the right prompt is key.

Whether you're migrating from popular EDA applications or starting fresh, mastering high speed PCB design has never been more intuitive. Flux enables teams to design, simulate, and route with real-time AI assistance, so you can spin your next high-speed board with total confidence.

Now, Flux Copilot can learn how you work—your design principles, part selection preferences, schematic style guidelines, and testing workflows—and remember them automatically.

Imagine an AI teammate that doesn’t just chat about your PCB ideas, but actively transforms them into schematics—placing parts, connecting circuits, and optimizing your design at your command, all through natural language. That’s exactly what the newly overhauled Flux Copilot does.

Creating a manufacturable, error-free PCB is never simple. Every engineer knows that missed details lead to production delays, costly revisions, and project setbacks. But what if you could have the power of a seasoned review team guiding you, 24/7?

If you’re using EasyEDA and are thinking of making the switch to Flux, learn how the two platforms differ and why Flux might be the next step in elevating your PCB design experience.

KiCad revolutionized PCB design by making it accessible to everyone. Flux builds on that foundation, offering a browser-based, AI-powered platform that takes your PCB design experience to the next level.

Flux Files centralizes your project docs, assets, and AI outputs in one tab so your team and AI always have the context they need.
