Arcpy (2.6) modify multiparts polygon vertice xy vlaue

tinyMee

Dear all,

I am using python2.6 (together with arcgis 10.0) and try to modify the vertice xy values for multiple parts polygon using the following scripts, no error thrown but the vertice xy value not changed. Please help to advice what is wrong in my script:

Apart from the indentation there are some funcional errors in your script. You only process the multipart polygons, while the final polygon is created from a arr_pol, which will be empty when the feature is not a multipart. You should process all features the same way regardless of it being multi or single part (all  the features in your sample data have only 1 part). If you don't do that and you write the original polygons when it is single part, you will get this:

And yes rounding the coordinates on 2 decimales is visible in you data. I didn't your code, but the da cursor (ArcGIS 10.1 and higher) which is far more efficient.
