Glossary
The antler is one element of the moose head.
An element is one of two or more individual mesh objects (that is, groups of contiguous faces) grouped together into one larger object. For example, if you attach one sphere to another, you create one mesh object from the two spheres. Each sphere is now an element of the object. Any function you perform on that object affects both elements. However, you can manipulate the elements independently using the Element sub-object level.
