Reads the project
Components, wires, terminals, cables and nets come out as JSON: the AI knows what's in the schematic and where, sheet by sheet.

The electrical CAD that speaks with artificial intelligence
WireCraft is a free, open source electrical CAD for schematics, power distribution boards and industrial automation. Every command is built to be used by you and by an AI: you design, it draws, numbers and checks.

Artificial intelligence
An electrical CAD AI knows how to use
Traditional CAD tools are only windows and clicks. WireCraft also has a language: every command has a name, clear parameters and a structured answer. It's the same language AI assistants speak. So the AI does the repetitive work, and you keep the decisions.
Draws like a designer
Places symbols and wires, tags components, numbers wires, builds terminal strips, bill of materials and wiring table. One command per action, nothing hidden.
Checks the work
Cross reference with issues in red, duplicate wire numbers, protection and cable checks in single-line diagrams: the AI finds mistakes before commissioning.
You stay in charge
Every change is a command you can read, undo and redo by hand. The AI saves you hours; the signature on the project stays yours.
you › On sheet 3 add start and stop for the conveyor with a run lamp. Then number the wires and update the bill of materials.
AI › Done. Here are the commands I ran:
cambiofoglio {"foglio": 3}
simbolo.sbnc {"at": [100,230], "funzione1": "Stop conveyor"}
simbolo.sbno {"at": [100,200], "funzione1": "Start conveyor"}
simbolo.km {"at": [100,140], "funzione1": "Conveyor motor contactor"}
simbolo.hl {"at": [220,140], "funzione1": "Run lamp"}
numerafili {"tutti": true}
uscita {"tipo": "distinta"}
✓ components tagged · wires numbered · bill of materials updated · cross reference clean
Example using WireCraft's real command names and parameters (in Italian). The 22-sheet sample project is generated by a sequence of commands like this.
TodayEvery command takes JSON parameters, from the command line and scripts: an AI can write them for you.

Electrical schematics
Orthogonal wires with automatic junctions, power rails, cross-sheet references and 52 IEC 60617 symbols drawn from scratch. Delete a symbol and the wire closes.

Automation
Component tagging in six modes, automatic wire numbering, live cross reference, tree navigator and "go to linked".

Terminals, cables, PLC
Terminal strips placed with a line across wires, jumpers, connectors, cables with their cores and PLC I/O cards with addresses and bilingual comments.

Lists and reports
Sheet index, bill of materials, terminal strips, wiring table, cable and I/O lists on the sheets, always updatable. Also in CSV and Excel.
- parts database
- price lists
- labels
Panel layout
From schematic to a scaled mounting plate, with DIN rails, cable ducts and dimensioned drilling. The door layout puts buttons and lamps on the front.
- layout manager
- thermal calculation
- drilling in CSV
Single-line diagrams
Distribution boards that size themselves: load current, protection rating, cable cross-section and voltage drop, with verification.
- Ib ≤ In ≤ Iz
- IEC 60364-5-52
- breaking capacity
- incomer and feeders
Translator
Dictionary in Italian, English, German, French and Spanish. A bilingual schematic with one command: functions, sheet titles and columns.
- IT · EN · DE · FR · ES
Print and PDF
Dynamic PDF with sheet bookmarks and clickable references. Coloured wires and everything else in black, ready for the customer.
- plant diagram
- floor plan
- terminal drawings
Gallery
Draw the schematic. The rest follows.
The panel layout comes from the schematic
Components and terminal strips land on scaled DIN rails between cable ducts. The mounting plate picks itself from standard sizes.
- footprints from part numbers
- dimensioned plate drilling
- rename a tag in the schematic and the layout follows
Distribution boards size themselves
Choose the load, power and line length: WireCraft proposes the protection rating and cable size, then checks everything.
- Ib ≤ In ≤ Iz coordination
- voltage drop from the origin
- change one value and the column updates
Deliverables ready to hand over
Coloured-wire schematics, thermal calculation, loop diagrams and wiring tables, generated from the project and bilingual, in a PDF with clickable references.
- bill of materials and wiring also in Excel
- printer labels in CSV
- bookmarks for every sheet

FAQ
Everything you want to know
Is WireCraft really free?
Yes. WireCraft is open source under the MIT or Apache-2.0 license, your choice: use it for professional work with no licenses, subscriptions or sheet limits. You can also modify and redistribute it.
How do you use AI with an electrical CAD?
In WireCraft every command has a name and JSON parameters and returns a structured result. An AI assistant can write the sequence of commands that places symbols and wires, tags components, numbers wires and builds the lists, then read the cross reference to check the schematic. The 22-sheet sample project is built exactly this way.
The next step is connecting your assistant directly to the open project through the Model Context Protocol (MCP).
Can AI get a schematic wrong?
Yes, just like a person. That's why in WireCraft the AI never works behind your back: every change is a readable command you can review, undo and redo, and the cross reference flags issues. Decisions and responsibility stay with the designer.
Can I open my existing projects?
WireCraft reads and writes DWG and DXF files and recognises sheets, titles, cross references, wires and contacts of existing schematics. Electrical data lives in block attributes, lists in CSV and Excel: your projects stay yours.
Is the interface in English?
Not yet: the interface is currently in Italian, while the translator already produces schematics in English, German, French and Spanish. An English interface is a great place to contribute.
Which operating systems are supported?
The ready-made executable is for 64-bit Windows 10 and 11. The code is written in Rust on a cross-platform CAD engine, CADCraft, so developers can build it from source elsewhere.
Is WireCraft suitable for power distribution too, not only for automation?
Yes. Besides machine and automation schematics, WireCraft draws single-line diagrams of distribution boards: incomer, busbars and outgoing circuits for sockets, lighting, motors, sub-boards and other loads, with their protective devices (MCBs, RCDs, isolators, fuses) and cables.
From the power and the line length it calculates the design current, proposes the protection rating and the cable cross-section (IEC 60364-5-52) and checks Ib ≤ In ≤ Iz, voltage drop and breaking capacity. Boards are then linked in the plant diagram and on the floor plan. Calculations assist the designer: final verification stays with the engineer who signs the project.
Which standards does it follow?
Symbols follow IEC 60617, reference designations IEC 81346 and cable sizing in single-line diagrams IEC 60364-5-52. Calculations assist the designer: final verification and compliance of the installation stay with the engineer who signs it.
