Hi Mike and other fellow users, 

I have an enterprise geodatabase polygon feature class, which is in a geographic coordinate system. I have a field: GIS_Area in the feature class, which I populate with the size (in hectares) of the polygons using a projected coordinate system.

My question is: can I use Attribute Assistant to do update this field ?

It seems that I cannot make use of Shape.STArea(), because the data source is not in a projected coordinate system. And I also when I change my data frame to the projected coordinate system, my other Attribute Assistant methods doesn't seem to work properly (INTERSECTING_FEATURE gives me incorrect results)

please could you give me some advise on my predicament ?

Kind regards

Pieter
