Hello. The problem is that i can't import 3D Model of LQFP64 package.EasyEda shows me "Error argument" error code.
I've downloaded it from "library.io" site, as you recomended. I tried to view the model in different 3D viewer programmes and everything were okey.
ZIP archive contains both *.obj and *.mtl files.
