Is there a way to create a polygon from a map frame extent in ArcGIS Pro?

[MarkBryant · Accepted solution]

You can do it via code.

import arcpy
#Reference the Project document from within PRO
aprx = arcpy.mp.ArcGISProject("CURRENT")
#Reference the layout
lyt = aprx.listLayouts("your_layout_name_here")[0]
#Get the Map Frame
mf = lyt.listElements("mapframe_element", "your_mapframe_name")[0]
extent = mf.camera.getExtent()
polygon = extent.polygon

You then have a polygon object that you can work with.

Note that this code just grabs the extent, if the map frame is rotated, the extent doesn't match what you see on screen.
