There is no order per se… however I have found that the order in which you select the items to be added or subtracted can make a difference in success or failure. I was having a hell of a time with the union tool on nameplates. Some letters just wouldn’t join the group. most of the time selecting those letters first, or in combination with other letters would solve it. Quite often actually. I made quite a few nameplates.
