This is a really great job, i can't find words to thank you.I just wonder if you kindly inform me, why some columns family gets a rotation or mirror (family flip control) after splitting them, noting that the lower body of the column doesn't take the same action.I mean that the column splitted for 2 parts, lower is in its original location and filp state, but the upper take a flip diffirant than the original, just in some cases.Is this a problem in my family or what do you advise regarding this.If you need some screen shots i can send them by mail
