I thought I would post the final script that created the expected results in the jpg file: def main():     import arcpy     # will overwrite existing jpg     arcpy.env.overwriteOutput = True     # read the parameter from the tool     loc_no = arcpy.GetParameterAsText(0)     # define the path of the mxd     mxd_file = r'H:\chris\{0}\{0} - actual_use.mxd'.format(loc_no)     jpg_file = r'H:\chris\{0}\{0}-actual_use.jpg'.format(loc_no)     if arcpy.Exists(mxd_file):         arcpy.AddMessage("Using MXD {0}".format(mxd_file))         try:             mxd = arcpy.mapping.MapDocument(mxd_file)             df = arcpy.mapping.ListDataFrames(mxd)[0]             arcpy.AddMessage("DF extent on startup is: {0}".format(df.extent))             arcpy.AddMessage("DF scale on startup is: {0}".format(df.scale))             lyr = arcpy.mapping.ListLayers(mxd, 'site_polygon', df)[0]             ext = lyr.getExtent()             arcpy.AddMessage("extent of lyr: {0}".format(ext))             new_extent = df.extent             new_extent.XMin, new_extent.YMin = ext.XMin, ext.YMin             new_extent.XMax, new_extent.YMax = ext.XMax, ext.YMax             arcpy.AddMessage("extent of new_extent: {0}".format(new_extent))             df.extent = new_extent             df.scale = 4000             arcpy.AddMessage("DF extent after assignment is: {0}".format(df.extent))             arcpy.AddMessage("DF scale after assignment is: {0}".format(df.scale))             arcpy.AddMessage("Exporting to JPEG: {0}".format(jpg_file))             arcpy.mapping.ExportToJPEG(mxd, jpg_file)             del mxd         except Exception as e:             arcpy.AddError("Error: {0}".format(e))     else:         arcpy.AddWarning("MXD {0} not found!".format(mxd_file)) if __name__ == '__main__':     main() Something interesting is that while the image exported is what I'm expecting: Nothing ever changed in the map window from when the mxd opened. I always expected that the extent would change in the map window and then the image would be created based on that: ... View more

Well, that worked! Nice clean results and the expected result on the map: Executing: ExportMXD2JPG32 LOC2016-003 Start Time: Fri Sep 02 08:42:29 2016 Running script ExportMXD2JPG32...

Thanks Xander. So with those changes it does seem to change the extent of the dataframe: Executing: ExportMXD2JPG32 LOC2016-003 Start Time: Thu Sep 01 15:53:39 2016 Running script ExportMXD2JPG32...

It seems to have dealt with the error. But the data frame extents still do not seem to take the value of new_extent. Thank you Dan ... View more

Thanks Dan. That seems to have fixed the error. The results now display as: Executing: ExportMXD2JPG3 LOC2016-003 Start Time: Thu Sep 01 14:35:03 2016 Running script ExportMXD2JPG3...

Hi Xander, I'm going to attach a file with a table showing on the left the code in the Calculate Value tool and on the right the code in the python script you sent me (thanks again!). The row below the row with the code shows the jpg file created using both methods. The one for the Calculate Value tool shows the correct image, the one for the python script shows the mxd as it appears when it's opened up (so it doesn't seem to do what's in the code). To me the code in both methods looks the same so I don't know why the code in the python script doesn't seem to run? ... View more

Great, thanks very much Xander. ... View more

So would the code in the script be the same as what I put in the Calculate Value tool and does the passing the parameter part get handled in properties > parameters when I create the script tool? ... View more

LocNo is just a string value that would be provided by the end user. Thanks ... View more

Actually, that would be my preference. I just haven't figured out yet how to pass a parameter from a model to a script. As you see I need to pass in a parameter LocNo. Can you point me to an example that would help me figure out how to do that? I would still need to make it part of a script tool as this is part of a larger model. Thanks Xander! ... View more
