very cool software - however files format is a nightmare ;).
I am the creator of the FreeCAD-PCB add-on that allows you to import PCBs into FreeCAD. I added support for LibrePCB - from now (if anyone is interested in this topic;)) it is possible to load boards directly from the LibrePCB to FreeCAD - for example to create a cover, etc. FreeCAD and FreeCAD-PCB are completely free.
All suggestions and information about errors are welcome.
