You can specify in which order overlapping model items are placed one behind the other in the modeling area.
In the example below, it is assumed that you have created the three objects 1, 2, and 3 in sequence. As the most recently placed objects are created at the highest level, object 3 is at the highest level and object 1 is at the lowest level. You want to reverse this sequence.
Procedure
Now, when you place the objects one behind the other they are placed in the order 1, 2, and 3.
In the same manner, you can place graphic objects such as squares or circles behind parts of objects to highlight these areas separately.
