just create a function within your script, def GetExtents(extents):     XMin = min([ext.XMin for ext in extents])     XMax = max([ext.XMax for ext in extents])     YMin = min([ext.YMin for ext in extents])     YMax = max([ext.YMax for ext in extents])     return arcpy.Extents(XMin, YMin, XMax, YMax) and within your main for the qualifying condition, df.extent = GetExtents(extents) ...

I agree Carl, I've been looking for other ways before actually, some lead to doing something with ArcObjects rather than python. But just for a stop-gap solution, and just utilising what already exist, this might suffice. You might also just create a batch command file as well and run as  a schedule task.  Although I read MXD doctor does a similar job in reducing file size as well. Regards, ... View more

I think you can easily get the target and join layers like this, inputLayer = r"...\testLayer.lyr" targetLayerName = (arcpy.mapping.Layer(inputLayer)).name fields = arcpy.ListFields(inputLayer) lyrList = [] for item in fields:     if ((item.name).split('.'))[0] not in lyrList:         lyrList.append(((item.name).split('.'))[0]) for lyr in lyrList:     if lyr != targetLayerName:         print 'Join Layer: '+lyr As for finding the join ID and type, no clue as well. Cheers ... View more

You need to go into python window, access the layer property name and use your inputs like, for lyr in lyrs:   if lyr.name == 'SITE Buffer':     lyr.name = 'SITE\r\nBuffer' For me "SITE\r\nBuffer" displays as "SITE\r\nBuffer"...what am I missing? I've changed it in the symbology label area, in the label appearing next to symbol, and in the layer name on the general tab? Thanks, Susan ... View more

I think what you can do since you have a one is to many relationship, to join it properly follow the link below, http://resources.arcgis.com/en/help/main/10.1/index.html#//0017000000v9000000 Regards, Thanos ... View more

Here is a sample code for the field calculator: def mean(field1, field2, field3):   fieldList = [field1, field2, field3]   validList = []   for i in fieldList:     if i != None:       validList.append(i)   meanVal = sum(validList)/len(validList)   return meanVal Hi Xavier! I think importing numpy for this case is a bit of a stretch since youll have to load numpy everytime you iterate thru the rows. Hows Davao by the way or are you in Manila? regards, Chris P. ...

Did you use the correct inputs for that export function? This small bit works actually, if mxd.isDDPEnabled:     ddp = mxd.dataDrivenPages     ddp.exportToPDF(r'E:\test.pdf','ALL') I have sample export code I did for my mxd's that are mixed DDP and normal ones: for mxdDoc in mapList:     mxd = arcpy.mapping.MapDocument(mxdDoc)     base = os.path.splitext(os.path.basename(mxdDoc))[0]     print 'Checking if DDP'     if mxd.isDDPEnabled == False:         pdfName = os.path.join(outPath, base +'.pdf')         arcpy.mapping.ExportToPDF(mxd, pdfName, '', resolution=300, image_compression='ADAPTIVE', layers_attributes='NONE', image_quality='BEST')     else:         if mxd.dataDrivenPages.pageCount <= 3:             for pageName in pageNames:                 mxd.dataDrivenPages.refresh()                 pageID = mxd.dataDrivenPages.getPageIDFromName(pageName)                 mxd.dataDrivenPages.currentPageID = pageID                 pdfName = os.path.join(outPath, base +'_'+str(pageName)+'.pdf')                 mxd.dataDrivenPages.exportToPDF(pdfName, 'CURRENT', '', 'PDF_SINGLE_FILE', 300, 'BEST', 'RGB',True, 'ADAPTIVE', 'RASTERIZE_PICTURE', False, True)         del mxdDoc, mapList del mxd Also you don't need to do "for" statement to get your text element since there is a wildcard. Just try, x = arcpy.mapping.ListLayoutElements(mxd, TextElement, 'wildcard')[0] ... View more

try ddp.exportToPDF Hi, I'm new to Python and trying to write a script that will do the following: 1.  Loop through all mxd's in a folder and edit a Text Element named "SubTitle" 2.  Save the mxd 3.  Export each mxd to pdf The problem is there are some mxd's with Data Driven Pages enabled, so I can't get the script to export ALL pages of a multi-page map.  I wrote an "if-else" so that I can distinguish the multi-page maps from the single page maps.  Everything else works fine except for the ddp map.  The error msg I get: ddp.ExportToPDF(mxd, basename, "ALL") AttributeError: 'DataDrivenPages' object has no attribute 'ExportToPDF' See attached screenshot of the code.

Hi buddy, Just look thru this documentation to have a feel for what you want to do, http://resources.arcgis.com/en/help/main/10.1/index.html#//00170000004m000000 Cheers Okay, thanks for that input, Thanos.  I have decided that an actual script within a toolbox is the route that I am going to go.  I have this worked out so far: import arcpy # Set the input workspace # arcpy.env.workspace = arcpy.GetParameterAsText(0) # Set the output workspace # outWorkspace = arcpy.GetParameterAsText(1) try:     # Get a list of the featureclasses in the input folder     #     fcs = arcpy.ListFeatureClasses()         for fc in fcs:           # Validate the new feature class name for the output workspace.         #         featureClassName = arcpy.ValidateTableName(fc, outWorkspace)         outFeatureClass = os.path.join(outWorkspace, featureClassName) def Reclass(symbol):   if MTFCC == "H3010":     return "River"   elif MTFCC == "H1100":     return "Creek"     except:     arcpy.AddMessage(arcpy.GetMessages(2))     print arcpy.GetMessages(2) Basically I am to the point where I tell it what to do and I'm not really sure how to do so. ...
