Automating capture of Extent from multiple mxds with multiple dataframes

[George Corea]

Hi,

I want to create a single shape file from multiple mxd's that have multiple frame sets with different extents in them. I have found/started a python script to do this (code below) but can't figure out how to write the captured X&Y Max/Min into the shape file that is created for this. See output below - an Attribute Error is generated.

I also want it to write the scale and title of the frame as well as the file name of the mxd in to the extents shape file.

Would appreciate your help in completing this script.

Thanks,

George

I noticed one problem. On line 5 you make the assignment mxd2 = glob.glob('*.sh p') and on line 12 you again use the identifier mxd2 in the for loop.

Here is some sample code that I was able to get working. You will need to create an array and add the XMAX, XMIN, etc to the array to create the polygon feature. Then you can create a feature class/shapefile from this array. I had trouble getting the Append tool to work with the array feature so I created a feature class for each extent, merged them together, and then deleted the original extent feature classes.

import arcpy, glob, os
from arcpy import env
from arcpy import mapping
env.overwriteOutput = True

path = r"C:\temp"
mxdList = glob.glob(path + "\*.mxd")

env.workspace = r"C:\temp\Test.gdb"

y = 1

for mxd in mxdList:
    mxd2 = mapping.MapDocument(mxd)
    dataframe = mapping.ListDataFrames(mxd2, "*")[0]
    frameExtent = dataframe.extent
    XMAX = frameExtent.XMax
    XMIN = frameExtent.XMin
    YMAX = frameExtent.YMax
    YMIN = frameExtent.YMin
    pnt1 = arcpy.Point(XMIN, YMIN)
    pnt2 = arcpy.Point(XMIN, YMAX)
    pnt3 = arcpy.Point(XMAX, YMAX)
    pnt4 = arcpy.Point(XMAX, YMIN)
    array = arcpy.Array()
    array.add(pnt1)
    array.add(pnt2)
    array.add(pnt3)
    array.add(pnt4)
    array.add(pnt1)
    polygon = arcpy.Polygon(array)
    arcpy.CopyFeatures_management(polygon, "Polygon_Extent" + "_" + str(y))
    y = y + 1


list = []

lstFCs = arcpy.ListFeatureClasses("Polygon_Extent*")
for fc in lstFCs:
    list.append(fc)

arcpy.Merge_management(list, "Extent")

for item in list:
    arcpy.Delete_management(item)
