^new^: Free Hmi Graphics Library

Standard icon sets often lack the specific symbols required for SCADA, PLCs, and industrial automation (P&ID symbols).

| Scenario | Recommended approach | |----------|----------------------| | (e.g., for Raspberry Pi) | Qt + OpenSCADA widgets + Material SVG icons (MIT) | | Commercial HMI device (no license fee for graphics) | Use MIT/CC0 icon sets only; code custom controls using basic shapes (no GPL assets) | | Web‑based HMI | Apache ECharts for gauges + FontAwesome + custom SVG mimic (Inkscape) | | Rapid prototype | HMI Project (GitHub) or ModernUI for WinForms (free) | | No time for DIY | Purchase affordable commercial library (e.g., Industrial Graphics from CodeProject, ~$50) – outside “free” scope, but practical | free hmi graphics library

Some industrial giants offer their full graphics libraries for free if you use their (limited) software versions: Standard icon sets often lack the specific symbols

Emerging tools like Stable Diffusion and DALL-E 3, when prompted with "industrial SVG, flat design, pump symbol, white background, no shadows," are beginning to generate usable assets. While they cannot yet generate state-based animations (Start/Stop variants), they are excellent for creating custom background dashboards or facility maps.

This article explores the best free resources available, how to implement them legally, and why "free" no longer has to mean "ugly."

You don’t need a large budget to build a professional HMI. Free graphics libraries offer a solid starting point for prototypes, small-scale factories, or educational projects. The key is choosing a library that matches your and license requirements .
