Hi all,

I just gained some skills of Vector Modeling for Points, Polylines and Polygons by using the XY-coordinates and the Z-value (elevation) stored in the geodatabases of ArcGIS 10.1 Desktop. I don't know anything about Raster, Triangulated Irregular Network (TIN), Terrain Datasets, and LAS Datasets.  I don't have ArcScene and ArcGlobe programs to create a new 3D feature.  Given the following data: (i) 4 locations with the XY-coordinates and the Z-value (elevation), (ii) collect soil samples at 2 depths for each location (i.e. 8 points), and (iii) the soil samples are analyzed for asenic, chromium and lead, I need to do (1) to create a 3D surface from the XY-coordinates and the Z-value of the 4 locations, and (2) to create a cluster of 8 points under the surface. In the program of ArcGIS 10.1 Desktop, how can I do (1) and (2) by using the ArcPy-Python programming? Please kindly help and advise me as much as you can.

Thanks in advance,
Scott Chang
