FAQ

Do my files get uploaded anywhere?

No. Every .epdz / .e3d is extracted, parsed and rendered on your device. Nothing is sent to a server — you can confirm by using the app offline.

Do I need EPLAN installed to use the viewer?

No. You only need EPLAN (Electric P8 2022+) to produce the .epdz export in the first place — see Exporting a Project from EPLAN. Opening and viewing it needs nothing but a browser.

The Project view is empty / greyed out.

That view is built from the archive's manifest.db. A standalone .e3d part or a .epdz without a manifest won't have it. Make sure you exported via Smart Production (not a bare model export).

I don't see my parts lists / terminal diagrams.

Report pages (BOM, terminal diagrams, cable plans…) are only in the .epdz if they were generated as pages in the project before publishing. Generate them in EPLAN, then re-export.

"View in schematics" is disabled for a 3D part.

That means the selected 3D object has no matching device in the 2D pages of this export (or the pages weren't included). Parts without a schematic counterpart can still be isolated, hidden and framed.

Which browsers are supported?

Any modern browser (Chrome, Edge, Firefox, Safari). A couple of conveniences depend on the engine:

  • Linking a folder / reopening recent files works only in Chromium-based browsers (Chrome/Edge), which support the File System Access API. Elsewhere, use Open file or drag & drop.
  • Keep screen awake appears only where the Screen Wake Lock API exists (most current browsers; not older Safari).

How do I stop the screen from sleeping during a review?

Settings → Display → Keep screen awake. It holds a screen wake lock while the tab is in the foreground, so the display won't dim or sleep. See Navigating the Viewer.

Is there a macOS app?

Not a prebuilt one yet. Use the web app or install it as a PWA today, or build the Tauri desktop shell from source. See Installing Covaga ECAD Viewer.

It's slow to open a big .epdz.

Large exports take a few seconds: the archive is decompressed (7-zip in WebAssembly) and the SQLite manifest is read, all client-side. Subsequent interactions are fast.

Can I contribute / report a bug?

Yes — issues and pull requests are welcome on GitHub. See CONTRIBUTING.md.

Is this an official EPLAN product?

No. It's an independent, open-source community project, not affiliated with or endorsed by EPLAN GmbH & Co. KG. EPLAN is a trademark of its respective owner.
