contours from points

[Kwiz]

I am using Civil 3d and have a file in which I have added points called all points- It has Northings and eastings and elevation. I want to add contours to a very basic file, I have gone though all the set-up and surface edits to display and add. Not sure where I have go wrong.

Thanks again I been using Cad for a long time and I have done something wrong- maybe its just me getting old .

Thanks againg KWIZ

Have you added them as a CIV3d Point group

 

 

 

Or as Autocad "Points"
