Surface Points

[tim_newsome]

It looks like a safe assumption but am still interested in hearing what the technical difference is in the point types of a surface in image

And your assumption is??

Not sure what you are asking.

Civil 3D has COGO points.
Civil 3D Surfaces have data points.
The are not related, unless you create a surface that includes COGO points as source data.
