I'm trying to perforate a pipe like shown on the attached youtube link, but when I get to the last step (Deleting the surface body) I lose my linear pattern.  I think it's because I'm referencing either side of it during the linear pattern, but so is he in the video.

How is he able to delete the surface body and still keep his linear pattern?  Maybe I'm "deleting" my surface body the wrong way..

Thx
