Applying Mesh to 3D nodes

[hawaiianivan]

I have downloaded a DXF file of a terrain (a DTM). Upon opening it in Autocad (and 3 different other applications), it transpires that the 3D data is 160,800 3D nodes. I need to convert these into a mesh, in order to export to a rendering programme. Simply put - does anyone know how to wrap a mesh on to these nodes? Or is there a smarter method to convert the whole thing into a 3D object?

Terrain or surface modeling software is designed to do just what you're after; create 3-d surface from nodes (points with elevations). Commonly used by surveyors and civil engineers, among others. Some common software is Autodesk's Land Development Desktop, Eaglepoint, many others. They create triangulated networks from the points, then create contours and meshes at user defined intervals (contours) and grid spacing and vertical exaggerations (meshes). An inexpensive program, CivilWorks, can be seen at

They have a freeware, but I don't know if it includes surface modelling in it.
