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/mer
Can anyone please help me to add the points of inner surface to the bigger surface.
Sounds to me like you have to merge the data to build a new surface
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).
