Hi Ray, you can find a lot of scripts on the MoI web site, go to http://moi3d.com and then the Resources page and go to the link for Petr's MoI page and Max's file archive. There are a lot of scripts collected in both those places and there are instructions for how to install a script on the FAQ.

Re: Loft with path - in MoI that is called the Sweep command, there is some information on it in the help file here:
