Commenting post [69](/?blog/2014-069): I'm not sure what goes wrong, maybe start with making sure that the downloaded .py files are importable in FreeCAD, for example by typing in the freecad python console (menu View->Views->Python Console): import dxfLibrary If no error appears that means the file is found... Make sure you type the names correctly... It's ~/.FreeCAD, not ./FreeCad, and it's /usr/lib/freecad/Mod/Draft not /usr/lib/freecad/Mod/Drafts.
