Insert cursor: Shape.STArea() and Length not updating?

MKF62 — Fri, 17 Apr 2020 21:02:31 GMT

Upon inserting a polygon (fgdb) into another polygon feature class (sde database), I've noticed that the inserted polygon has null for Shape.STArea() and Shape.STLength(). I thought these were supposed to be automatically calculated and updated upon inserting any shape using any method. Is that not the case? Do I need to take Shape_Area and Shape_Length, put them in my row, and then insert those values as Shape.STArea and Length?

ArcMap 10.7

I don't have an answer to my question, but I'm just going to use append which is probably a more proper way to do it anyway.

I think you could copy across just the SHAPE@ token and it would contain those attributes, but that's really just a guess. Or try running calculate geometry.

@DavidPike is correct. Using 'Shape@' instead of 'Shape' as the fieldname lets cursors know it is a geometry.
