Flip Edge
Ribbon: Topoplan – Modify TIN > 
Flip Edge
Menu: Ground – Editing TIN > 
Flip edge
Toolbar: Editing TIN > Flip edge
Command line: NG_MESH_FLIP
The command changes the edge position between two triangulation faces in the surface model (SubMesh or Polyface mesh); it can be performed, for example, to turn edges along the slope crest, road side, etc.
When you run the command, an object snap is enabled, and then you should specify an edge for a flip.
When you hover the cursor over the mesh, two adjacent triangles the position of face between which will be changed are highlighted in red. A click on the face flips the edge.

The position of several faces can be subsequently changed. Pressing ESC ends the command.
