Cross-fading
Cross-fading transforms a shape from one form to another, with
OpenOffice.org handling all of the intermediate transitions. The result
is a new group of objects including the two end points and the
intermediate steps.
To carry out a cross-fade, select both objects (hold the Shift key while
selecting each object in turn) and then choose Edit > Cross-fading
On the Cross-fading dialog, choose the number of increments
(transition steps). You probably want to have Cross-fade attributes and
Same orientation both checked. The end result is shown in Figure 182.

Combining multiple objects
Using Draw, you can combine drawing objects together in two distinct
ways: grouping and combining. These two methods allow you to treat
multiple objects as one unit, or to merge objects to form a new shape.
Grouping is like putting objects in a container. You can move them as a
group and apply global changes to them. A group can always be
undone and the objects that make up the group can always be
manipulated separately.
A combination is a permanent fusion of objects leading to a new object.
The original objects are no longer available as individual entities and
the operation is not reversible.
