I have disabled “Shadow effects” which I assume is the drop shadow on entity boxes, but they still remain. The shadows are unhelpful when a relationship line comes in from the right as a crow’s foot can be almost completely hidden by the shadow. Perhaps the relationship graphics can have a higher z-order than the shadow if they can’t be turned off?
I have attached an image demonstrating how the cardinality symbols can get hidden (right one is fine, left is hidden).
Shadows can be turned off.
When I turn it off, the cardinality symbols are displayed fine.
To turn it off for all entities in WS at one jump, right-click the Workspace | Workspace Format | Shape tab and clear the Shadow Effect checkbox.
To turn it off for new WSs and new models, see the Settings menu | Options | Physical model | Shape | Shadow Effect.
Please let me know if it solves your problem. Thanks in advance.
