When I create a circular pattern of say a hole, and I specify equal spacing on 360deg.  Is there someway to reference those values in other dims?  For instance say I put 4 holes around a 360 circle.  Then I wanted a construction line directly inbetween two of the holes no matter how many holes I pattern(modify existing pattern) around the circle.  So if changed from 4 holes to 16 holes the construction line would still be inbetween the two holes.

Thanks
