I want to permanently turn off centre marks being entered on view creation. I know I can uncheck the insert centre marks on view creation in document options but is there anyway I can permanently do it so I don't have to remember to do it before every drawing. I have tried unchecking it and then saving that as our standard sheet format but next time you open it the box is checked again. Some of our suppliers CAM software are picking up the centre marks and causing all sorts of probelms.
