Displaying a Centroid on Surfaces

[SwChilly]

Here's an odd question.

 

I am using Civil 3D 2013. My project manager would like to see centroid of a surface displayed, so he can determine lengths and flows from the centroid to the property line and so forth. Is there a way to display them, or even determine where it is located (then I can just through a block and label or something)?

 

I tried googlin it but it keeps bringing up stuff for MAP 3D.

Tell your boss there's no centroid of a 3D object like a surface: "centroid" is a Gis definition, suitable ONLY to topological 2D polygons.

Maybe make a boundary then you could find centroid after convert to pline, also flows would'nt that be from highest point not centroid !
