KKE Circuit
Start free trial

A drawing canvas built for engineers, not designers.

Browser-native canvas built on Konva.js. Click-to-place from the symbol library, wires that hop crossings, multi-sheet packages with automatic Sheet X of Y numbering, A0 to A4 page sizes, customisable title block — for teams in Worldwide.

For Worldwide: KKE Circuit is available across Global in English. Region: Global (INT).

The canvas

  • Click-to-place from the symbol library; symbols snap to a 20 px grid, annotations to 10 px.
  • Smart non-overlapping placement — the canvas finds an empty slot for newly placed parts.
  • Drag-select with marquee, click to edit properties in a side panel.
  • Wires with auto-hop arcs over crossings; floating-net warnings (red outline).
  • Manhattan or freeform routing; press R while wiring to flip the routing axis.
  • Wire properties: colour (IEC code), cross-section (mm²), cable reference, voltage drop.
  • Net labels for cross-sheet connectivity — same name on different sheets = same net.
  • Annotations: text, lines, rectangles, circles, leader lines.
  • Multi-sheet drawing packages with automatic Sheet X of Y numbering.
  • Page sizes A0 → A4, portrait or landscape.
  • Customisable title block with placeholder fields that resolve from project metadata.
  • Undo / redo command history, keyboard shortcuts, right-click context menus.
  • Auto-save every 60 seconds.

Multi-variant symbols

One library part can store up to seven variants of itself — schematic, single-line, three-phase, P&ID, control, panel front view, terminal — and the canvas picks the right one for the drawing type. Add a contactor once; it shows up correctly on every drawing it appears on.

Custom symbol creator

A grid-based editor for engineers to build proprietary or vendor-specific symbols:

  • Place lines, rectangles, circles, paths and text on a 20 px grid.
  • Define pins with name, label, edge (N / S / E / W), type (power / control / PE / signal) and kind (electric / air / oil / water) — the kind drives auto-colour on P&ID lines.
  • Pick a component type (motor, contactor, sensor, pump…) which sets the default reference-designator prefix.
  • Save per-variant: same custom symbol can have different geometries for SLD vs P&ID vs panel layout.
  • Org-scoped library plus globally shared symbols.

Standards and templates

Master templates are shipped for every drawing type at every page size (A0 → A4), each with a title block in the bottom-right whose placeholders resolve at draw time. Organisations can save their own templates with their own title block, logo and standard notes.
