I am working in ArcMap 10.3.0 and exporting through Data Driven Pages (DDP). The DDP export works as expected the first time and for immediate subsequent exports, but if I use DDP to export again after more than a minute or so (the time varies) from the same MXD, the program hangs and I have to shut it down through the Task Manager.
I can tell if it is going to hang up as soon as I click "Export" because the Export window does not show "Page x of x" text. See screenshots here: https://geonet.esri.com/message/536459#536459. Even if I let the computer run for awhile, the "Page x of x" text never appears and the export does not happen. This only happens on subsequent exports after more than a minute from an MXD.
This seems to happen whether I export a single page or the entire document the first time. However if I resave the MXD with a new name and then export, it always hangs up and requires ArcMap to be restarted. The problem seems to occur whether I am creating a new PDF file or overwriting an existing PDF file.
- My map consists of an ESRI aerial basemap (no other raster layers), with five 10000' x 10000' lidar contour shapefiles and about 10 other small vector shapefile layers.
- My export settings are: 300 dpi resolution & output image quality/resample ratio 1:2.
- I am working from a data server located in this building, but the connection speed varies.
- Another co-worker is having the same problems with the same MXDs on his machine.
Edited to add this error message: It appeared after ArcMap was hung up on a subsequent export, and hit "end task" in the Task Manager. This is only the 2nd or 3rd time I've gotten this error message, but I thought it might be relevent. (Also, I don't have an f:/ drive as shown in the error message.)
Someone else had this problem as asked on GeoNet here: https://geonet.esri.com/thread/161564 No solutions were presented to her question so I wanted to ask again here.
Is there any way to prevent ArcMap hanging up on a subsequent DDP export?
Edited to add this code snippet, which produces multiple exports without hanging:
import_path = r"R:\Projects\Project\GIS\MXDs\Project_property_maps.mxd" # Path of .mxd export_path = r"C:\Users\user\Desktop\test\Test" # Path of output file field_name = "Project_INDEX.Pg_num" # Name of field used to sort DDP pg_name = "Project_INDEX.Desc_" # Name of field used in PDF file name mxd = arcpy.mapping.MapDocument(import_path) for i in range(1, mxd.dataDrivenPages.pageCount + 1): mxd.dataDrivenPages.currentPageID = i row = mxd.dataDrivenPages.pageRow print row.getValue(field_name) arcpy.mapping.ExportToPDF(mxd, export_path + row.getValue(pg_name) + ".pdf") del mxd
