show features created after flatten before flatten....?

I have a solid bent to a large radius. To show the finished part accurately, I need to flatten it, cut a piece out of it, and show the bent part, with the piece removed. I guess the easiest analogy would be a cylinder full of circular holes. To be accurate the holes must be created in the flattened state, but shown in the rolled state. How is this done?

Thanks,

Mike Lydon
