The properties pallatte has both these scales listed. In theory, they can be different. But in practice they can't. I would love to be able to plot my drawing at 1:1000 with the civil objects & labels scaled to 1:500 so they don't overwhelm the plan. It would seem I should be able to simply set the viewport to have a standard scale of 1:1000 and annotation scale 1:500 and be done. But it doesn't work. It will always scale the annotative objects to the standard scale.
My workaround is to scale my sheet double size and plot it half size, to trick the Civil objects & labels. But what? why? how is it meant to work. Surely you can do better than this?!
Credit where credit is due! Give kudos or accept as solution whenever you can.
Civil 3D objects and labels were created prior to the annotation scale being a part of AutoCAD (2004 was the first "release" of Civili 3D and 2007 annotation scale was introduced into AutoCAD). Because of this, the Civil 3D objects have always reacted to the viewport scale. I agree, they should react to the annotation scale but they don't.
