I am wondering if anyone has figured out how to build a TIN in ArcGIS from a shapefile made up of triangles with values attached to the triangles.
Essentially I have a TIN in shapfile format and don't want or need any sort of interpolation of the data. All I want is to be view/use the TIN in ArcGIS.
None of the tools under 3D Analyst Tools > Data Management > TIN allow me to do this, i've tried most if not all of the combinations....hard replace which you would think would work, does work but only for a few triangles at a time and i'm working with millions.
I've found an old article on stack exchange asking the same thing ( Creating TINs in ArcGIS from triangular elements? - Geographic Information Systems Stack Exchange ) and tried LandXML to TIN too and it hasn't worked. The stack exchange post refers to notifying ESRI regarding this issue and was wondering if there has been any progress?
