I am a new user nx6 coming from solidworks. I have created a revolved surface and only want to keep a piece of pie from it. I have sketched the profile I want to keep on its face and am stuck right there. is there a simple trim surface to curve function I am missing?

You should use "Trimmed Sheet" option but be careful about the vector direction.

thanks for the tip but it wont let me select my revolve as a sheet unless i go back to the revolve feature and change the preference to a sheet body which it also wont let me do. sheesh i coulda done this in solidworks in about 2 minutes. ugnx6 powerful but ponderous? any additional tips appreciated

Maybe an extrude intersection from the profile you want along the revolve axis?
How would you do it in solidworks?
