I'm working with a cylinder with hole configurations down the length of it. Is there a way to set up planes that always do a cross-sectional view of the holes? I want to cut the assembly in half and have the cut go along a plane that goes through the holes so I can present progress.

Currently, in an assembly I go to the sketch command and pick the feature I want to cut through and draw a line through it. Then I create a plane relative to that sketch and a parallel sketch face. What is wrong is that when I move the part the sketch stays in the same spot while the holes rotate of it. Is there a way to have the sketch stay with the holes? Or is there a better way? My way is a little time consuming and I was looking for a better way. Thanks.
