You can move a mono footing by clicking and dragging it.
To move a mono footing:
Select the footing to move.
Position your pointer over the
center grab handle to display the Move cursor.
Click and drag the footing to move it.
Release your mouse button.
Note: When you move a mono footing, it becomes detached from the column. Therefore, if you move the column, the footing will not go with it. If you want to re-attach a footing to a column, you will need to delete the footing, then insert a new one.
