Symbol catalog

The editor includes professional catalogs with ISA-5.1 geometry organized by discipline.

Palette

• Instant search by name, type or category.
• Favorites ⭐: star symbols to keep them at hand (persisted).
• Recents: the symbols you use appear in a quick section.

Custom symbols

Create your own blocks from primitives (rectangle, circle, line or freehand):

1. Draw the geometry and select it.
2. Press the block button in the toolbar and choose Save selection as symbol.
3. Give it a name and category; it is stored in your browser and appears in the palette.

Manage your symbols (rename, recategorize, delete) with the gear ⚙️ in the palette.

Data-driven annotations

When you edit block attributes, the symbol shows an automatic annotation below whenever the value exists, e.g. Q=150 m³/h on a pump, V=25 m³ on a tank, Cv=12 on a valve or 45 kW on a motor.

Instrumentation

• Instrument bubbles (transmitters, indicators, recorders) with ISA letters and loop number.
• Control valves and actuators.
• Control loops and signals (electrical, pneumatic, digital).

Chemical / Process

• Towers and columns (distillation, absorption).
• Tanks and vessels (atmospheric, pressurized).
• Heat exchangers.
• Pumps and compressors.

Electrical

• Motors, generators, transformers.
• Switches, contactors and protection.
• Power and control symbols.

Civil

• Layout plans, buried pipes, drains.
• Structures and platforms.

Mechanical

• Valves (globe, butterfly, gate, ball).
• Pipe elements: elbows, tees, reducers, flanges.
• Inline instruments (orifices, flow meters).

Signal lines

• Symbols for electrical, pneumatic, hydraulic and digital signals per ISA-5.1.

Each discipline provides its own geometry and catalog so the drawing stays consistent with the standard.
