This is an issue I've been fighting with for a while, maybe someone has an answer. In chief architect Premier, when moving walls on some plans, the walls never snap to a whole inch. For instance, The dimension of a room is 10'6 7/16. I don't want it to be 7/16". I need it to be 10'6, but it never allows me to move it to the whole inch, every move includes 1/6ths of an inch. Using Cntrl lets me free move the wall, but I really just need it to snap to whole inches, and not some fraction thereof. It's one of the more frustrating issues of chief architect. I like being able to move the wall by fractions of an inch if necessary, but I need it to allow me to snap to a whole number.
