You opened a new panel project and, before drawing a single line, you did three things: found the installation media, entered the license key, and checked the version delta from last week. The administration was done before any engineering had started.
You should not need that much administration to draw an electrical schematic. Open the browser, open the site, start drawing. EupCAD is built for exactly this experience: a drawing environment that needs no desktop CAD install, no license key, and no upload of your project to any server.
The hidden cost of desktop CAD
Heavy CAD packages are powerful, but every project carries the same overhead:
- Install & updates: workstation installs, version deltas, incompatible add-ons.
- Licensing: per-seat licenses, annual renewals, unlicensed sessions in the field office.
- File transfer: DXF files travel by email, USB and cloud — every transfer is a corruption risk.
- Split context: the drawing in one program, the BOM in another, the address list in a third.
And think about this: you have several copies of the project file, and finding which one is the latest takes ten minutes. This overhead is heaviest for small offices.
What a browser-based CAD changes
In a browser CAD, the install step disappears entirely. The current version is always served; you just type the address. Your project file stays on your device: in EupCAD, projects are created in the browser and downloaded as a single file. If the file is not meant to be shared, it is never shared — because it never left your machine.
This guarantees two practical things:
- Data sovereignty: your schematic, device list and addresses stay on your device.
- Single source of truth: the project is one file; the "which one is final" question disappears.
Your first schematic in 5 minutes
When you open EupCAD, you are greeted by a ready demo project, not a blank page: a panel with power distribution, a VFD pump circuit, a 24 V control circuit and PLC I/O — 10 pages. Browse the pages, click devices, open reports — learn what the application produces before you start.
Then open your own page. The flow is four steps:
- Create a project — new project and first page.
- Add symbols — search the 802 ready IEC 60617 symbols for a contactor, relay or motor circuit breaker and drop it onto the page.
- Draw connections — draw the wire; automatic addressing and IEC 81346 labeling fill in the terminals.
- Generate reports — download BOM, terminal and cable schedule as CSV; export the schematic as PDF or SVG.
When the drawing is done, the engineering data is ready too: device counts, terminal schedule, cable list. There is nothing to copy into a spreadsheet by hand — the application takes care of it.
Start from the library, then extend it
The built-in library has 802 ready IEC symbols, searchable by name, category or letter. If you need a custom symbol, you can import your own — the library grows with you.
What you need to start
No license key, no account, no install disk. A modern browser is enough. The application also works offline, so you can keep going even on a weak field connection.
Open EupCAD and browse the demo project's pages; then move on to your own panel. Your first schematic takes less than 5 minutes.
