The new Label Leader command in Civil 3D 2010 has provided us with a very popular SOLU-AROUND. We now have the ability to drag the profile structure label left or right of the structure and the leader remains at the top of the structure.
No I’m not kidding, I haved looked for this since the 2007 version!
Let’s look at 3 simple steps to conclude this solution.
Select the label and drag it directly above the structure. (Confirm ortho is on before dragging)
Right click, and select Toggle Label Pin
Select the rectangular grip (marked with the pin) and drag it to display properly
