Thanks for your help @Anonymous User . Unfortunately, when I tried your suggestion...
aprx = arcpy.mp.ArcGISProject("CURRENT")
m = aprx.listMaps("811Tickets")[0]
lyr = m.listLayers("AZ811 BlueStake")[0]
lyt = aprx.listLayouts()[0]
mf = lyt.listElements("mapframe_element", "MainMapFrame")[0]
lyrExt = mf.getLayerExtent(lyr, False, True)
mf.panToExtent(lyrExt)
mf.camera.setExtent(lyrExt)
I found that it works the same as...
aprx = arcpy.mp.ArcGISProject("CURRENT")
m = aprx.listMaps("811Tickets")[0]
lyr = m.listLayers("AZ811 BlueStake")[0]
lyt = aprx.listLayouts()[0]
mf = lyt.listElements("mapframe_element", "MainMapFrame")[0]
mf.camera.setExtent(mf.getLayerExtent(lyr, False, True))
I'm trying to stay at a scale of 1:25,200, but the both of these scripts zoom to the feature's/layer's extent.
If I figure it out, I'll post my corrected script.
