It may not be complicated but you don't describe which direction you copied the lines or how far. why would you even want to use Curviloft of those lines? What sort of result are you expecting?
I am using a workflow process that is not uncommonly used in Rhino to connect two planes or surfaces without using arcs. I am trying to use simple geometry as a test first before it would be used later on a more complex model. I like to test things like this out on simple models before I try incorporate it into my modeling process, and I noticed this was causing sketchup to freeze on OSX. I am not sure if the same behavior happens in Windows as I am not at work to try it in that environment.
