Hi Larry, if you need install instructions for any of the scripts above, please see FAQ #1 : How do I install a plug-in script?

For your 2nd request, flattening a generic curved surface with actual "minimal distortion" is a big complex area of work. But if you want it for use in Flow you probably don't want minimal distortion, you probably want the same distortion that Flow will be using anyway. For that try the script from here: http://moi3d.com/forum/index.php?webtag=MOI&msg=6067.23 - that one you set up on a shortcut key and just paste the entire script that's shown in the message into the Command part of the shortcut key instead of copying any files around.

Hope that helps!
