How do I import PCB symbols, footprints, and models into my ECAD software?

Install and run the Library Loader app (available for download HERE). Subsequent ECAD model downloads will go straight into your ECAD Tool.

Some 3D models are available in .IGS format and are compatible with major ECAD tools (AutoCAD, Autodesk’s Fusion, CATIA, Solid Edge, SOLIDWORKS) or can be opened with open-source software (IGS Viewer, ShareCAD, SketchUp, eDrawings Viewer).
