We have survey information of a bridge and terrain in the same file.
I am almost sure there is no way to have one surface because the bridge is overlapping the terrain.
Some way I can have one surface of this information? Please see the pic.

The quick answer is No, you cannot have overlapping surface data in a Civil 3D TIN Surface.
You should maintain the original ground as a surface and model the bridge. Displaying both together will look good. You can create a surface for your bridge, but leave it separate from the og. If you have InfraWorks, modeling bridges is very quick and design transfers to Civil 3D easily.
Thanks! I am doing exactly that!
I wanted to be sure if that is a new feature in 2021 version, but it is not!
Thanks!
Why are these triangles missing or going wrong way, because the breaklines are crossing?
Yes, a few 3D Polylines are overlapping but with different elevations. You cannot create vertical triangles (for walls). Simply move the lower 3D Polylines at least 0.001 m outside, then the surface rebuilds as expected.
