IDF

The Intermediate Data Format (IDF) is a 3D CAD data exchange format which is specifically designed for the import and export of PCB data. It consists of two files, a component library (* .emn) and a layer assembly file (* .emp). The component library file contains information about the PCB dimensions (PCB outline), the position and orientation of the components, the position of the mounting holes, cutouts and the barrier areas, the layer assembly file contains information about the file dimensions and the height of the individual components.
