Original User: ManninWe are trying to create a new PDF for each polygon in our feature class.The scale must stay the same, so the page size needs to change.This also means that DataDrivenPages isn't a workable option for us for these products.We are exporting the dataframe, not the page_layout so that we can manipulate the page sizes programatically.My current problem is that the resulting PDF does not have the same extent as what I see in ArcMap.I've attached images of the ArcMap dataframe (inside layout view) and the pdf export. The exported PDF page size seems to be correct, so I believe we are converting from inches to pixels properly.But, I don't know why the extent does appear as expected.Any suggestions are greatly appreciated.Here's my test code that I run from the Python window in the mxd:import arcpy, os, math, time
arcpy.env.overwriteOutput = True
mxd = arcpy.mapping.MapDocument("CURRENT")
df = arcpy.mapping.ListDataFrames(mxd)[0]
df.scale = 31680 # set and keep dataframe scale at 1 inch = 1/2 mile
BULayer = arcpy.mapping.ListLayers(mxd,"BidUnits",df)[0]
arcpy.SelectLayerByAttribute_management(BULayer,"NEW_SELECTION","BID_UNIT = 8") #run on just one feature for testing
df.panToExtent(BULayer.getSelectedExtent()) # center dataframe on selected feature centroid
#get real world distance of selected feature - ArcMap 10.1 and later returns dataframe CS units on .getSelectedExtent call
#current dataframe CS is Web Mercator
y_dist_meters = BULayer.getSelectedExtent().YMax - BULayer.getSelectedExtent().YMin
x_dist_meters = BULayer.getSelectedExtent().XMax - BULayer.getSelectedExtent().XMin
#buffer the extent by a mile on each side
y_dist_meters += (1609*2)
x_dist_meters += (1609*2)
#convert distances to inches from meters
y_dist_inches = math.ceil(y_dist_meters * 39.3701)
x_dist_inches = math.ceil(x_dist_meters * 39.3701)
#calculate page size
y_inches = math.ceil(y_dist_inches / df.scale)
x_inches = math.ceil(x_dist_inches / df.scale)
print str(x_inches) + " x " + str(y_inches)
#set dataframe height and width
df.elementHeight = y_inches
df.elementWidth = x_inches
arcpy.RefreshActiveView()
#time.sleep(30) #test to see if a complete redraw affects results
#calculate page size in pixels based on pdf export resolution
pdfRes = 300
dfew = int(x_inches * pdfRes)
dfeh = int(y_inches * pdfRes)
PDF = "C:/gm_sts/bidunitmobilemaps/pdf/testing2.pdf"
#mxd.save() #test if mxd save affects results
arcpy.mapping.ExportToPDF(mxd,PDF,df,df_export_width=dfew,df_export_height=dfeh,resolution=pdfRes,image_quality="NORMAL",layers_attributes="NONE")
