What is a .EPW file?
An .epw is a SamacSys ECAD Model wrapper - a small stub the SamacSys / Mouser ECAD Part Wizard expands into a schematic symbol and PCB footprint. Created by SamacSys.
- Did you know
- The free SamacSys library service supplies ready-made symbols and footprints for millions of parts, delivered as tiny .epw reference files.
- Analyser handles .EPW alongside related formats such as .SchDoc, .SchLib, .PcbDoc and more.
- In Analyser's format library, .EPW sits in the 3D / CAD / engineering category.
- What Analyser shows you
- Open Altium Designer schematics, circuit boards and projects in the browser. Analyser reads the OLE compound-file streams of schematic documents (.SchDoc) and symbol libraries (.SchLib), and PCB documents (.PcbDoc) and footprint libraries (.PcbLib), and rebuilds the geometry as an interactive vector view: schematic symbols, wires and pins, or the board outline, copper, pads, tracks and arcs - with pan, zoom and per-layer visibility toggles. It surfaces the component part numbers, datasheet and supplier links, the pad table and the layers used, reads the project manifest (.PrjPcb) with its member documents, and decodes the SamacSys ECAD Model wrapper (.epw). Nothing is uploaded.
- Open a .EPW file
- Drag a .EPW file onto the Analyser home page (or tap to pick one). It opens entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
