Snap objects with respect to each other
The Section Designer allows you to position shapes on your canvas by positioning two objects with respect to each other.
Note:
When you select multiple objects, the squares that surround the object that you have last selected are gray.
The squares that surround previously selected objects are white.
The color is important for snapping the items. The object that you want to move should be surrounded by grey squares, whereas the sqaures around the other object should be white.
If you select the objects in the wrong order, then you can hold the Shift key down and click over the object twice (to deselect it and then select it again). You can also old the Ctrl key down and click the object.
