  •                                    WHAT IS THE TIN SURFACE

The triangular irregular network (TIN) surface is a consisting of triangular faces of the triangular surfaces in the digital formate. The vertices of the triangles are created from field recorded surveying data. The survey is done by like as Total station survey, GPS RTK, PHOTOGRAMMETRY, etc.

In this article, I describe methods of creating a TIN surface from two software.

          HOW TO CREATE TIN SURFACE FROM AutoCAD CIVIL 3D.

        Open the AutoCAD civil 3d > Go to the new > Select in the file name- Autodesk Civil 3D (Metric) NCS.
