If you are unsure how to do this, refer back to Page 4. Once you have created the group it should become the current group (check the popup menu... it should show the name you just typed). If for some reason the new group is not the current group, select it with the popup or by using the "Prev" and/or "Next" buttons. With the new group selected, click the "Add All" button. The ball should turn completely red. This button puts all of the polygons that make up the ball into the current group (as you might guess, "Remove All" does just the opposite, and leaves the group empty with no polygons selected... but do not do that right now).   FYI: The selection you made for group_1 is still there. If you select group_1 with the popup, you will see the selection go back to what it was before. Each group is completely independent, and selecting or deselecting polygons in one group has no direct effect on the others. It is also quite possible, as in this example, for groups to overlap, meaning that some of the same polygons can be a part of more than one group at a time. In this case, since group_2 at the moment contains all of the polygons in the ball, it also therefore includes the polygons in group_1.   The ball with all polygons selected.
