What is a .SchLib file?
A .SchLib is an Altium Designer schematic symbol library - the reusable component symbols placed on a sheet. Created and opened by Altium Designer.
- Did you know
- Each symbol in a .SchLib carries its pins and the part parameters (manufacturer, part number, datasheet) used to build the bill of materials.
- A symbol library lets a team reuse approved parts, each tagged with the manufacturer part number that flows into the bill of materials.
- The schematic symbol is the abstract pin-and-name view of a component, paired with a .PcbLib footprint for its physical pads.
- 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 .SchLib file
- Drag a .SchLib 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.
