2D-surface from Assembly

[FC2008]

Hi, I have made an model symmetric around an axis from which I would like to extract a 2d surface.

I've revolved several parts 90degrees and assembled them.
I would not like to use the surface for FEM analysis.
I know there is a way to do this in SolidEdge, I just can't remember how.

Anyone know? thanks.

If someone is interested in a detailed explanation, I will be happy to write one out for you.
