Thanks for looking into this Jeff It is a requirement that comes out of a large automated mapping application that I wrote for a large government mapmaker. The application produces PDFs of standard maps at 3 scales and for ad hoc extents at 7 scales. It supports 4 projected coordinate systems and dynamic tables. To achieve this it has a map for each projected coordinate system, another for a geographic coordinate system, two more for overview and index maps, plus another used for the dynamic tables. Whenever the application is run, which happens via a Python script tool with many options, one option is to save a copy of the project in the state that it was immediately prior to the ExportToPDF on its Layout. The reason an operator may do this, which they frequently do, is to be able to open that copy of the project and then do some manual touch ups in ArcGIS Pro before re-exporting to PDF as a final map.  They are cartographers so it is impossible to write code for all their possible ad hoc requirements. This works reasonably well, but a cartographer may be thrown if the last time the master project was saved, the project was open to one of the maps when they normally work with the Layout. I'm really just wanting to be able to use ArcPy to set which view from Layout, Map1, Map2, Map3, etc the saved copy of the project will open to when they double-click the <copy>.aprx. ... View more

Thanks Kory and Xander The key thing is that the main map on the layout is bordered by an irregular polygon.  It is defined as a rectangle in lat/long, but the map has to be presented in a projected coordinate system (usually one of three MGA Zones, sometimes Albers/Lamberts), and so the rectangle becomes a distorted "rectangle" with many thousands of vertices.  This distorted rectangle is available as a polygon feature in a feature class. What I am looking for is to be able to set a read-write property of a MapFrame object to set a graphic clip by the only polygon in a file geodatabase feature class, and to be able change that property to be another feature class when required. The grids and graticules, data and MapFrame border already seem to graphically clip to a free-hand polygon so the main block (besides ArcPy accessibility) seems to be that the clipping polygon cannot be specified as a polygon feature. ...

Dynamic Tables appear to be coming at ArcGIS Pro 2.1: If you need something sooner, and are comfortable using ArcPy with ArcGIS Pro, then I have blogged about a technique I use to do this at https://community.esri.com/people/graeme/blog/2018/01/16/adding-multi-page-tables-to-arcgis-pro-layouts-for-pdf-export-using-arcpy ...

I'm glad you raised this because I am encountering the issue of the Layer class method no longer being Read and Write too.  Unfortunately, in my case I don't think the "updateConnectionProperties" method can be used to restore my workflow. The coding pattern that I need to work or workaround is: import arcpy aprx = arcpy.mp.ArcGISProject(r"C:\temp\test.aprx") mapx = aprx.listMaps("Map")[0] lyr = mapx.listLayers("Test Layer")[0] lyr.dataSource = r"C:\temp\test.gdb\testFC2" https://gis.stackexchange.com/questions/254548/switching-data-source-of-layer-to-new-feature-class-using-arcpy-with-arcgis-pro ...

Thanks Craig I'm participating in 2.0 Beta so I'll try to extract this project from the enterprise it sits in to try opening it on my personal laptop that is at 2.0 Beta. - Graeme ... View more

I'm starting to get a feel for ArcMon and it appears that the majority of the time (about 100 seconds each) is going on opening three maps that have their file geodatabase feature classes stored in GDA94 (GCS) being displayed in three MGA Zones (PCS). I do this so that the same project can be used to support deciding on the fly which of those MGA Zones should be used to display the data (my ArcPy code makes the others invisible) based on where in the map series (cursor of a map index feature class; not in-built Map Series) a particular map sheet is located. In ArcMap I could have decided the spatial reference of a single data frame as the script runs, but in Pro the map frame is "locked" to a map and it is the map that has the coordinate system rather than the map frame.  If there is another way to support this requirement I would be keen to know it. ...

Thanks Sean I had tried to use that but had not succeeded in opening it using Ctrl-Alt-M while "Opening Project" was proceeding. I now realize that I should start ArcGIS Pro, then  Ctrl-Alt-M, before opening the project. Now I just have to try and figure what it is telling me. There seem to be some 25 second hangs so I'll use that blog post to try and understand them. ... View more

In my project which takes 5-10 mins at the "Opening Project" stage, I have 4 maps and 3 basemaps, as well as a layout that has a map frame for each of them plus about another 30 layout elements. I suspect that the only way that I will be able to speed it up will be to try and reduce the number of maps. Originally, I thought layers accessing enterprise geodatabase layers may have been the main issue but even when I switch this to being all local (file geodatabase) subsets of those layers the slow "Opening Project" remains. A tool which could monitor and report on what takes the time when "Opening Project" would be very useful. ... View more
