When you need to move, scale or rotate multiple objects as one unit it is easier if they have been grouped together so that they transform as one unit.
Many primitive objects in Maya are grouped objects. For example, the NURBS cube primitive is comprised of 6 flat squares or planes that have been grouped together as one unit. When the plane objects are grouped together they create a hierarchy.
A hierarchy is a collection of nodes or objects that are connected together to form a unit for some purpose. Hierarchies are useful for describing how the objects within them share similar characteristics or attributes; move, scale, rotate for example.
To group the objects for the column
It is important that you do not select any of the templeBase objects as part of your selection. If you accidentally select any of the base objects, deselect them.
Leave the other options at their default settings
Maya groups the objects together in a hierarchy. You will learn more about hierarchies in the steps that follow.
