Map Properties Arcpy

Question

Hi,

I am attempting to change the map properties of my ArcGIS Pro Map using ArcPy, though I am struggling to find out how.

target_crs = arcpy.SpatialReference(32632)

arcpy.env.OutputCoordinateSystem = target_crs

arcpy.env.geographicTransformation = target_crs

Tried these and have yet to succeed, any ideas?

Cheers,

Stewart

Thanks! My solution was found through your link which linked into a different one.

map_view = arcpy.mp.ArcGISProject("CURRENT").listMaps("Map")[0]
map_view.spatialReference = arcpy.SpatialReference(32632)
aprx = arcpy.mp.ArcGISProject("CURRENT")
aprx.save()
