+    only have their respective components in X, Y, and Z.
+
+    Parameters
+    ----------
+    obj: Part::Feature
+        Any type of object that has a `Part::TopoShape`

+        This means most 2D and 3D objects produced

+    -------
+    Part::FeaturePython
+        A scripted object with `Proxy.Type='Array'`.
+        Its `Shape` is a compound of the copies of the original object.
