Placing 3d objects on surface

[jake.ingle]

hello,

I'm just trying to get a grasp on Civil 3d and could use some advice on placing a 3d drawing from autocad onto a surface. So what I have is some survey points that I shot and turned into a surface. Now I would like to place  3d drawings of  features onto the surface.I would like to shift the features around and find the right spots for them taking into consideration slope and existing terrain. Then I would like to turn these placed features into survey points that can be found in the real world. Is there an easy process for something like this? Thanks

Create a feature line , move it to the surface and then use the set points on object (measured/divide.).
