There may be times when you need to retrieve the geometric definition of features in a feature class. ArcPy provides the ability to read this information through various objects.
In ArcPy, feature
classes have associated geometry objects including
MultiPoint that you can access from your cursors. These objects refer to the
shape field in the attribute table for a feature class. You can read the geometries of each feature in a feature class through these objects.
Polyline and polygon feature classes are composed of features containing multiple parts. You can use the
partCount property to return the number of parts per feature and then use
getPart() for each ...
