Select both surfaces holding control, then select intersect in the editing group of the model tab. That will create a curve at the intersection of the two surfaces.

Once you have a surface selected the intersect command should not be greyed out.
Thanks for your help, user interface has changed so much since last used creo..I should say proengineer
