3D data from EAGLE
IDF (Intermediate Data Format): A data format that contains only coordinates and outlines of PCBs, drilled holes and components. Each individual 3D component must be read by a third party tool or by MCAD software and placed at the intended position. IDF can be created with EagleIDFExporter.ulp.
A very elaborate solution, which reads into Sketchup using the eagle_export.ulp, as well as other programs and plug-ins. Sketchup can not read-in STEP-files neither can it output them. 3D components must be created and assigned.
