Every object on the page occupies a specific position within a design's z-order (stacking order). With overlapping objects, this will determine which parts of the object are exposed and which are hidden.
When objects are placed or drawn, they are assigned a position in the currently selected layer's z-order. This initial position is determined by object targeting. However, all objects can be repositioned within a layer's z-order as needed.
To change an object's z-order position:
Select one or more objects.
From the Toolbar, choose one of the following:
Move to Back—repositions the selected object(s) at the bottom of the layer.
Back One—moves the selected object(s) down one position in the layer.
Forward One—moves the selected object(s) up one position in the layer.
Move to Front—repositions the selected object(s) at the top of the layer.
