Hai,
I have two surfaces with useful information in both of them as in the figure. I need to merge two surfaces into a single surface retaining the points in both of them.
I have tried the solution mentioned in this thread: http://forums.autodesk.com/t5/AutoCAD-Civil-3D/merge-surfaces/td-p/1943072 but the points of inner surface are lost when I did the merger.
Can anyone please help me to add the points of inner surface to the bigger surface.
Thank you

Sounds to me like you have to merge the data to build a new surface

Make sure that your inner surface is pasted, into the new surface, last. The past order matters, the last surface wins.
Thanks,
1. Create a new surface (COMBINED) and paste the large surface into it
2. Extract the boundary of the inner surface and add to the COMBINED surface as a non destructive breakline
3. Paste the inner surface to COMBINED
This assumes that the common boundary between the two surfaces are at exactly the same level which is unlikely and if this isn't acceptable then simply omit step 2 and the resultant TIN will replace everything in the outer surface TIN that is covered by the inner surface TIN (again this may not be desirable).

if your just adding new points to better build the surface rather than adding a surface to another surface to overwrite data in a particular area all you have to do is go to your original surface in toolspace that you are adding to. under the point group add the new points to the tab, this will automatically update the original surface you have built with your new points, you will most likely have to flip some edges to achieve the desired contouring
It would be a kindness to other users if you accepted which solution was the one you implemented that worked for you.
Just a thought.
