Adding features to TIN

[KyleGallagher]

I've created an empty TIN and am trying to add features to it.  The TIN, the points feature class, and the buffer shapefile all have the same geographic coordinate system.  I am getting the following error:

Traceback (most recent call last):
  File "C:\Projects\Tulsa_District\Scripts\dem2pts2TIN.py", line 107, in <module>
    gp.EditTin_3d("tin_2ft", "Data.mdb\elev_pts GRID_CODE <none> masspoints true; buffer.shp <none> <none> hardclip false")
ExecuteError: ERROR 050035: No features were added to the TIN
the input string is not a geographic or projected coordinate system
Failed to execute (EditTin).

Is there something wrong with the code as shown above?  The points feature class causes the gdb to be around 860 MB, even after compacting, so I'm wondering if Edit TIN just can't process that much data.  Any thoughts?

Thanks!

It turns out my TIN was getting too big (around 10 million nodes) and so it wasn't creating all the way.  I broke my buffer shapefile into 2 parts and created 2 TINs successfully.

I had to same problem with 9 million points using ArcGIS ArcInfo 9.3.1.

I went to a machine with ArcGIS Desktop 9.2 and was able to do it without any problems.
