INTERACTIVE PROOF · STRUCTURED ECAD

Electrical drawings backed by a queryable model.

The drawing is one view. Switch states, live paths, isolation points, and export data come from the same topology.

Loading verified case…

480 V radial distribution

Open any switch. The drawing recalculates immediately.

Hover, focus, or select a device to inspect it. Dashed switch targets can be operated.

WHY A MODEL

Topology is a fact the machine can check.

The same 33 components can describe two different systems. One integer exposes the difference.

“480 V, 3 phase … 6 × 1200 A fused disconnects … each will feed 2 × 600 A disconnects … each will feed MCCs.”

VERIFIED · RADIAL

32 wires · every wire has 2 ends

Each feeder is explicit. MCC-07 resolves to feeder 4 without guessing.

REJECTED · SHARED BUS

27 wires · one wire has 7 ends

The model declares “radial,” so a multi-terminal bus is a machine-checkable violation.

THREE QUERIES · ONE MODEL

Do the checks. Do not take the claims on faith.

LIVE

Connectivity

Open feeder 4. Two MCCs and their downstream disconnects lose power. The source-side terminal remains live.

LIVE · SAFETY

Isolation list

LOTO procedures are written safety documents. The graph finds every lock point, including reverse-feed paths.

ADAPTERS PLANNED

Export

Stable component IDs and terminal references are the handoff boundary to PLCopen XML, AutomationML, TIA Portal, and CODESYS.

Select a query above. Its result will be computed from the same fixture that renders the drawing.

SCOPE · HONESTLY MARKED

What the engine supports.

Implemented and planned formats are deliberately separated.

IMPLEMENTED

  • Single-line diagramsRadial and bus topology
  • Control schematicsContacts, coils, seal-in logic

MODEL-DERIVED

  • Terminal and jumper schedulesQueried from nets and terminals
  • PLC I/O diagramsGenerated from point data
  • Wiring tables and cable listsQueried from connection data

PLANNED

  • Ladder diagramsPLCopen XML exchange path
  • P&IDDEXPI model path

OPEN MEANS SPECIFIC THINGS

The format and validation rules are open. The engine is not.

Components have stable IDs. Wires connect terminals, not vague boxes. Topology, layout, operating scenarios, and symbols stay separate.

You can inspect the schema and run the same acceptance fixtures used by this page.
