This solu-around rotates point styles (symbols) without rotating point label styles (text). Notice below the default behavior. Select the circular grip and the symbol and text is rotated.
At this time Civil 3D 2011 the effective solu-around is to change the point label style behavior setting for orientation reference from object to view. If the reference is set to object the text rotates with the object, but if this is changed to view the text is oriented with the view. See image below to set the point label style to view.
Now as the symbol/point is rotated the text remains oriented to the view.
To obtain desired results, create a new label style for symbols that may require rotation or create a point group with a point style override and only include the points that are rotated.
An alternative solution is to create a dragstate and set the point label style to stacked text. With this method only one color can be selected for the text. Drag the point to the right, and rotate the symbol using the circular grip. The text remains in the dragstate without rotating the text. Below are the settings for the dragstate and expected results.
New point style for the symbols that require rotation. Set the rotation custom to the style.
