Only use this option if you are using Rhino 6 only.
eleFront can be downloaded at food4rhino, and saved in your Components folder.
To install eleFront through the Package Manager, open Rhino and type
PackageManagerin the command line, then search for "eleFront".
If you are using Rhino 6, the command is
_TestPackageManager, and it will take a moment to load all of the plugins list.
