Lets us understand the concept of group
and combine in depth and compare both of them using certain commands.
1. Open Corel Draw.
2. Draw rectangle using Rectangle and fill it with
red color. Keep it selected.

3. Go to Edit > Duplicate
4. You will get another rectangle filled with red
color. Fill the second rectangle with green color. Keep them side
by side, on the same level with a very less space in between. Select
both of them.

5. Go to Arrange > Group
6. Both the rectangles are grouped and still filled
with the different colors.
7. Go to Arrange > Ungroup
8. Now the rectangles are ungrouped.
9. Go to Arrange > Combine
10. The objects are combined and filled with single
color.

11. You need to do this smoothly as we are going to
use the same rectangles further to explain the difference between
group and combine.
12. Go to Arrange > Break
Curve Apart
13. Click anywhere to deselect the object. Select
any object using Pick Tool. You will observe that now you can select
any object separately and fill the color of your choice.

14. Delete any one rectangle. Select the rectangle
left on the page. Click on the fill tool and select Fountain Fill
Dialogue. Select Radial in Type and Two Color in Color Blend. Choose
any colors for From and To boxes. Click OK to fill the radial fill
in the rectangle. Keep the rectangle selected.

15. Go to Edit > Duplicate
16. You get another identical rectangle with redial
fill. Please try to observe the nature of the radial fill in those
two rectangles. They have two centers.This means both the rectangles
have their own identical separate radial fills. Keep them side by
side, on the same level with a very less space in between. Select
both of them.

17. Go to Arrange > Group
18. Both the rectangles are grouped and still filled
with the separate radial fills.
19. Go to Arrange > Ungroup
20. Now the rectangles are ungrouped. Select both
of them.
21. Go to Arrange > Combine
22. Both the rectangles are combined. Now please carefully
observe the fountain fill. When grouped, the fill are separate with
two centers in each rectangle. After combine command is applied,
both the rectangles are treated as one
single object and hence the two fills are turned into one single
fountain fill. This fill has one center and both the rectangles
are treated as big one single rectangle.

23. Go to Arrange > Break
Curve Apart
24. The object is separated again and we have two
different rectangles with two separate radial fills.
