My plot scale is set to mm and my annotation scale is 1:500 which matches my viewport scale (XP factor = 2). When I create a new viewport the labels appear. When I change my UCS and do the plan command, I lose my scale. I regen, and set my scale up again only to lose my labels. Sometimes only my surface labels disappear and sometimes the alignment labels and the surface labels disappear. It makes no sense to me.
I am teaching a Municipal Design course and don't like telling the students to use trial and error.
HELP!!!
