Is there a way to control in which order the contours or breaklines are used in building a surface? Default the breklines are used in this order: 1-2-3-5-4 as the image on the right. The only way to produce the surface on the left following the order 1-2-3-4-5 is to make two different surfaces 1-2-3-4 and 4-5.

I would recommend not making the surface on the left as a single surface. In variable you will have a common xy with different z value and Delaunay Triangulation algorithm with have a hiss fit.

Thank you for your answer!
I even tried to paste two surfaces together but they rebuild and turn to the one on the right!
But I think the order in which one picks the breaklines should matter and be there as an option!

I have five sets of breaklines.
Doing the way you suggested does not do it!
I moved them up and down rebuilding the surface without any effect!
Sorry!

You can't make a TIN Surface in Civil 3D that looks like the image on the left no matter how you pick or order the breaklines. TIN Surfaces are not allowed to have vertical edges or overhangs.
You could make an AutoCAD Solid or Mesh that looks like that, but that surface can't be used with the civil engineering commands in Civil 3D.

Peter,
I've looked at his image twice and I don't think that's a vertical surface. It looks like it is steep but not vertical. If it IS vertical, maybe he can adjust point 5 a little so that it wouldn't be.

It's not vertical. Peter just noted that C3D can't have vertical OR overlapping faces (overhangs). The OP's desired surface does have overlapping faces.
