Three types of symbol
The same equipment drawn three ways, so the symbol matches the screen or the document it goes into.
Realistic (with volume)
Illustrated equipment with shading and depth, for overview screens, presentations, training and documentation. Every colour is editable.
Browse 3,695 symbols →ISA-101 flat 2D (for HMI screens)
Flat, grey, low-contrast symbols for operator screens: colour is kept for equipment state and alarms only. State variants come as separate files.
Browse 3,411 symbols →Schematic (P&ID, electrical, fluid power)
Line symbols for P&IDs, electrical, instrumentation and fluid-power diagrams. Drawn from scratch; not certified against the standards (see the notice on each page).
