We've created a layout that is a template that we'd like to use for a dozen maps.
Here's what we are doing:
- in catalog, make a copy of the layout and the map
- open the copy of the map and make the desired layer changes/adjustments
- open the layout, and change the map referenced in the map frame to the new map
- wait while arcGIS Pro hangs forever...
We've tried on multiple computers without success. If it makes any difference, the project and data are all accessed via UNC paths. Looking at the performance tab of task manager, nothing (GPU, Memory, etc) seems to be maxing out.
