I drew it out and it looks like it's clockwise, non-intersecting.

KevinBell

GCS_WGS_1984 is the spref of the FC I'm inserting into.

DarrenWiens2

What is the spatial reference of your 'polygon' feature class?

DarrenWiens2

How does it fail? With an error? If so, what's the full error?

I suspect it's because you don't set a spatial reference anywhere, but we'll see.

DanPatterson_Retired

is the polygon ring (aka points) clockwise in orientation? and non-intersecting? (i'm not going to draw it out... the numbers just got weird)

KevinBell

when I pass in the -111.8256, 40.691085 as above a record is created in the table, but w/ empty geometry.

this doesn't work:

Can you provide an example where it fails? Or does your given example fail?

DanPatterson_Retired

Kevin can you format your code using syntax highlighting /blogs/dan_patterson/2016/08/14/script-formatting

EDIT What are the longitudes and latitude? some example? longitude first (X), latitude 2nd (Y)
