Frequently asked questions
What is Unifilar?
Unifilar reads electrical single-line diagrams and turns them into structured data. It parses AutoCAD DXF files, identifies the equipment and the connections, and hands the result to the simulation tools that need it.
Which formats does it export to?
DigSILENT PowerFactory as CSV for power system modelling and load flow, and ETAP as XML for short circuit and arc flash studies. The conversion between CAD and simulation is the step that normally has to be retyped by hand.
What does the AI recognise in a diagram?
Transformers, breakers, inverters and the electrical connections between them, classified automatically rather than transcribed by an engineer reading the drawing.
Can it be used from another system?
Yes. There is a REST API with API key authentication, rate limiting and Swagger documentation, which allows diagrams to be processed in batch instead of one at a time.
Can I check the result before exporting?
The diagram is rendered at 300 DPI with image export, next to the structured data, so the extraction can be reviewed against the original drawing before it goes into a simulation.
