Create duplicate polygons using Shape@ and Geometry objects in 10.1

Greetings All

I have a shapefile with 1 polygon in it. I want my script to read the geometry of the polygon and then create multiple polygons in the same file from the original polygon.

I can do this using Describe, ShapeFieldName & a polygon array. But I noticed new python functionality using Shape@WKT and FromWKT

The help section is truly lacking (even by ESRI standards) and I was wondering if anyone can help me join the dots.

It looks like you can use "Shape@WKT" to extract the polygon geometry and put it into a Geometry object, like so:

infc = "D:\\DDP_extent.shp"
infcFields = ["SHAPE@WKT"]

g = arcpy.Geometry()
gList = arcpy.CopyFeatures_management(infc, g)

The writing geometries help section only uses arrays as the input method, but surely I could use FromWkt to create a new geometry object for the InsertCursor?

Am I reading it right? or are arrays the only way to go?

Thanks in advance

ANSWER FOUND

(I cant believe it was this simple....as the ESRI help was not helpful at all)

infc = arcpy.GetParameterAsText(0)
repnum = arcpy.GetParameterAsText(1)

gRows = arcpy.da.SearchCursor(infc, "Shape@")
for row in gRows:
    origpoly = row
del gRows

aRows = arcpy.da.InsertCursor(infc, "Shape@")

for x in xrange(0, int(repnum)):
    aRows.insertRow(origpoly)
del aRows
