Steve Jobs once said “...there's just a tremendous amount of craftsmanship in between a great idea and a great product.” We agree wholeheartedly.
However, as PCB designers, it’s not always easy to demonstrate the thought and craftsmanship that went into your design. Other EEs might be able to appreciate your effort and understand the inner beauty of your work, but first, they’d need access to your design files and a compatible tool. Non-EEs may not understand the beautiful intricacies of your design, but they can appreciate a good layout and an aesthetically pleasant board.
In either case, we want to help you better demonstrate your craftsmanship. With automatic, realistic 3D renderings of your PCB, Flux is making this a reality.
Flux's new rendering capabilities automatically create the most realistic and beautiful representation of your design possible. No extra effort is needed to master rendering tools, and no experience is necessary. Now, anyone can effortlessly create stunning, dynamic, and professional 3D renders. And since Flux is browser-based and free to use, anyone can access your renders in real-time with just a link.
But why does this reality matter?
We understand that craftsmanship matters, detail counts, and extend that thinking to how you present your work. Login to your account to see how your projects look with the new rendering engine. 🚀

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

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.

This Spring 2026 updates make hardware design faster end-to-end with a more capable, self-correcting AI agent, improved AI auto-layout that needs less cleanup, sourcing-aware design with real-time pricing and availability, and templates to start from.

This update brings more than just polish—it’s the foundation for a faster, more fluid design experience, built around the way Copilot is used today and the way we see it evolving tomorrow.

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

We're excited to unveil our Smart Polygon system in Flux! This powerful capability builds on top of our automatic copper fills to transform how you create and manage custom copper areas in your PCB designs.

Whether you’re routing high-speed buses, fine-tuning antennas, or laying out clean RF filters, sharp 90º or even 45º angles can be a serious bottleneck. Now, you can create precisely curved elbows across entire nets—or dial them in trace by trace—with full control over radius, inheritance, and overrides.

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.
