Getting current map frame extent without having to save the project each time?

EricEagle — Mon, 03 May 2021 19:43:27 GMT

I can get a map's view extent by doing this:

p = arcpy.mp.ArcGISProject('CURRENT') m = p.listMaps()[0] e = m.defaultCamera.getExtent()

However this is real janky because a user can move the map and re-run the code, and it doesn't update until the project is saved. This has been the case from what I can tell, for around five years now.

Maybe it's easier to explain what I need to do. In a script tool, I need to set the arcpy.env.extent parameter to "Same as display" but do it with python rather than forcing a user to manually select "same as display" in the GUI every single time.

Is there a "best practice" to implement this behavior in python? I had read that this property was made available to python sometime recently, but I can't find any documentation on it.

aprx.activeView.camera.setExtent(ext) # and there is getExtent

It think that this is full circle and the setExtent and getExtent were added in recent versions of Pro.

I don't know how otherwise you would implement this in a python script other than grabbing this parameter after the script is actually run
