import feature, how to develop sheet metal?

[Diego.Mochen]

good evening to all, I have a folded sheet to u, and I would like to create development for laser cutting.
the part is imported from solid edge, so the feature tree does not have the history of processing, there is only the icon that reports: Import feature id157. I press that I have just started to use creo, so I am a little acerbo; If anyone can give me some advice, I'd be grateful.

Hello, everyone.

Start here. If you place your file and it's not too complicated I'll take it back to you in creo 6.
