Help Creating TIN with Python Script

GeorgeHaskett

Hello,



For some reason when I cannot get the following script to work:



# Import primary modules
import arcpy, sys, os, traceback
from arcpy import env

# Set Variables
inTinA_features = arcpy.GetParameterAsText(0)
out_TinA = arcpy.GetParameterAsText(1)
spatial_ref = arcpy.GetParameterAsText(2)

# Create TIN
arcpy.CheckOutExtension("3D")
arcpy.CreateTin_3d(out_TinA, spatial_ref, "inTinA_features Elev_Obs masspoints <None>", "DELAUNAY")
arcpy.CheckInExtension("3D")

The script was stripped down to the bare bones, but still is not functioning.
I am using Python 2.7 with ArcGIS ArcInfo 10.1.

The error I get is as follows:

Traceback (most recent call last):
File "C:\Users\George\Documents\ArcGIS\v2\ProGIS_Project\createTIN.py", line 11, in <module>
arcpy.CreateTin_3d(out_TinA, spatial_ref, "inTinA_features Elev_Obs masspoints <None>", "DELAUNAY")
File "c:\program files (x86)\arcgis\desktop10.1\arcpy\arcpy\ddd.py", line 1683, in CreateTin
raise e
ExecuteError: Failed to execute. Parameters are not valid.
ERROR 000800: The value is not a member of <None>.
Failed to execute (CreateTin).

Failed to execute (createtin).



Thanks in advance,

Thanks,

I finally managed to figure out my multi day headache.  Its all due to typos on ESRI's website in their help section none the less.

In two different examples they use string values, not variables or boolean, but text words such as :

[INDENT]"constrained_delaunay"
"Delaunay"[/INDENT]

The Data Type actually needs to be Boolean and therefor either a True or False.....

Thanks,
