Using erwin Data Modeler r9, how can I prevent the Drawing Objects to overlay on the Relationships?

Description:

Using erwin Data Modeler r9, when I place an Object Drawing on a Model, it ALWAYS is on top of the Relationships.  Even when selecting the Object Drawing and then selecting 'Send Backward' or 'Send to Back', it does not become the layer beneath the Relationship lines.   I can not use Object Drawing to enhance my models.  How to do I prevent the Object Drawing to appear on top of the Relationship lines?

Solution:

In the Model Display, Right-Mouse-Click on an empty space and select Properties | Display tab.  On the Bottom left in 'Preferences' section,  select the Check box for "Display Lines on top" and click OK. That should keep the Relationship lines on top of the Drawing Objects.
