Objects may lie on top of other objects. You can change the front-to-back order of the objects in your drawing using the Bring to Front or Send To Back commands under the Arrange menu.
The Bring to Front and Send to Back tools are found on the Design tab.
Any object that you insert into your visual can be formatted to be in the front or back. Bring to Front moves any selected objects in front of the non-selected objects. Send to Back does the reverse. These commands have no noticeable effect unless objects overlap one another.
To bring an object to the front of the Work Area, select the object then choose to Bring to Front. Alternately, to send an object to the back, select the object and choose to Send to Back.
