I used to believe that in Autodesk Civil 3D 2005 it was only possible to change the area labels of parcels one at a time. What that means is that if I labeled many lots and then created a new label style, I would only be able to change the labels one at a time to the new style.
Well, after some clues found in the Discussion Groups I found that if I selected multiple lots in the Toolspace then Right-Clicked on the column that I wished to change, i.e. "Area Label Style", I could then choose "Edit..." This would bring up the "Select Label Style" dialog box. When a style is selected and the "OK" button is pressed, that style would be assigned to ALL of the selected Parcels.
This removes one item from my wishlist.
