Assembly Cut:"Intersection curve" HELP!

Hello SW users.

I have an attached assy file that consists of 3 prt files. Withinthe assembly I must create an intersecting cut in the horizontalpipe, where the pipe intersects the lofted part. I started out myconverting the entities using the "intersection curve" function.This created a 3d sketch automatically. I'm now having difficulitycutting this 3d sketch with the cut-extrude command.

Please see if you can assist.

Thanks,SolidworksAssemblies
