When I use the measure tool and select 'Planar', I get 28,400.30ha as my result, which is the result I want to add to my attribute table. When I run the area calculation tool, regardless of which coord system I select, it always returns the geodesic area of 28,391.997ha. The data is stored in GCS, so this makes sense, but I'm looking for a function that will calculate the planar area based on the current projected coordinate system of the map. ArcMap can do this with no issue, but it appears ArcGIS Pro is lacking this functionality. What I'm after is essentially a !shape.planarArea@hectares! expression, but that doesn't seem to work.
