Help for Data type in Model Builder's Calculate Value

SamJenkins1

Hi,

I'm looking for some help formatting the output of my calculate value process so that it fits a particular data type to be used in a geoprocessing tool.

Specifically I'm trying to get an origin for the Grid Index Features tool. I created a Calculate Value and wrote an expression using variables defined in the model, set the Data type to "Point". Now, I think, I need to set the output of my calculate value function so that it matches the format of the Point data type. But I cant seem to find what that format should be.

Any help would be appreciated. Is there help page for Calculate Value that I've missed?

Cheers
Sam

The help topic Data types for geoprocessing parameters may help you. 

The string representation of a point data type is simply a string with the x and y coordinate separated by a space.  Code sample #4 for Grid Index Features shows using a point for the origin_coord:

import arcpy from arcpy import env arcpy.env.workspace = "C:\data\ProjectData.gdb" arcpy.GridIndexFeatures_cartography("gridIndexFeatures", "", "", "", "",                                     "1000 meters","1000 meters",                                     "-6000000 -1600000", "15", "20",)

In calculate value, your code block routine just needs to return a string with the x and y coordinate, separated by a space.
