I created a model in ModeBbuilder, and I exported the model as a script, but when I try to run it I get the following error. I have added my error below and the code below that. Thanks for any help.

Error: Traceback (most recent call last): File "C:\Temp\VirtualCampus\IGIS\IGISprogrammingscript_1.py", line 43, in arcpy.MakeFeatureLayer_management(Points_of_interest, Pointsofinterest_Layer, "", "", "FID FID VISIBLE NONE;Shape Shape VISIBLE NONE;CATEGORY CATEGORY VISIBLE NONE;NAME NAME VISIBLE NONE")

Here is my code:

The parameters for MakeFeatureLayer are:

MakeFeatureLayer_management (in_features, out_layer, {where_clause}, {workspace}, {field_info})

Your parameters don't seem to fit into this format. perhaps try fixing it 

arcpy.MakeFeatureLayer_management(Points_of_interest, Pointsofinterest_Layer, "", "", "FID FID VISIBLE NONE;Shape Shape VISIBLE NONE;CATEGORY CATEGORY VISIBLE NONE;NAME NAME VISIBLE NONE")

not exactly sure what you are trying to get out of it.

does the line below fix your error?

arcpy.MakeFeatureLayer_management("Points_of_interest", "Pointsofinterest_Layer")

  • Hi, thanks for your help. I tried inputting your code, but it still produced the same error. I have three shapefiles, and am creating some new files from this, so a buffer, then using the buffer and one of the shapefiles to create a clip etc. I'm creating the model and then exporting the script, and running it in arc. The assignment is to create a model, export it as a python script, and import it as a script and in theory it should run like the model.... – user19831 Jul 12 '13 at 21:52
  • Try removing this line: Pointsofinterest_Layer = Points_of_interest – artwork21 Aug 11 '13 at 1:42
