Group
Earlier I used CorelDRAW, I found two term, Group and Combine. At first I can't find the difference, because the view is almost the same, then finally I realized that those two things are different when we take a real closer look.
Group is "binding" two or more object become a cluster, but each object still maintaining their attributes such as Fill, Outline, etc. When we click once, automatically the other object included in the group will also be selected. With the grouping objects we can apply the same formatting, properties, and other changes to all the objects
within the group at the same time. We can also make group other groups to
create nested groups.
