SolidWorks 2011 Unfold, Unwrap or Flatten 3d surfaces

Hi everyone!

I was wondering, if is there a way to "unfold, unwrap or flatten 3d surfaces" directly in Solidworks, I mean without the plugin from "Solid3dtech". Here's a video: www.youtube.com/watch?v=IANwktAm-9w.

I create an extruded spline, then I pick the option "convert to metalsheet" but is not possible add folds.

Is it possible to create a flat metalsheet, give the shape of that spline, and get unfold? If not, is there another way to do it?

Thank you guys.
