Phyton script from Modelbuilder (9.3.1 SP2). Command error

[CarlosVillalba_Alonso]

Dear colleagues,
I'm having a problem with a py script generated from a Model (export to py). The model works fine, and input and output projection data is included, but the script gives an error while projecting data, and it looks like is not taking the input data projection info when exporting to py.

I can not see where the problem lies, especially because the model works fine, but I need script to create a daily execution task.

Below is the history record of the operation, highlighted in bold the command and the error message.

Any help is appreciated.

The model builder export to python is just a tool to help convert a model to a script, it is not a perfect conversion and requires modifications to work after the conversion. Also if you want help with your script you should post your script not just the error you receive.

[T__WayneWhitley]

Just to give you a little more info on what to look for, the input coord system is not defined as you stated - the evidence is with your provided statement here:

<Parameter Label="Input Coordinate System" Type="Scalar">Unknown</Parameter>

If for some reason it isn't being read properly, then you need to fix that -- your output coordinate system appears to have been set okay, but I assure you no 'project' will work without info on both 'from' and 'to' coordinate systems.  You may have to properly Define Projection on the input dataset before attempting to Project it.

The problem is solved. Apparently, the key was that in the feature class created from event layer the projection has to be defined before executing the command gp.Project_management.

As a sum up of the thread, I would stress that exporting models to py does need editing and revision after the automatic code generation. For instance, you have to specify to overwrite in the gp object, and so on.
So the 'export to script' action in model builder it is a good tool, but it does not guarantee that if the model works the generated script will work straightforward.

Thanks to those who responded.

See below the right code:
