How to hide relationship names?

I have names for relationships like “FK_account_id” and so on. How to hide names when I print the diagram or export it to graphich file?
In rightclick - Workspace Format -Entity I haven’t find some related things.

Hello student7,

This option is not available in current TDM3 version. However, I’m pleased to inform you that this request (entered under # 37 229) has already been implemented to next Beta 3.1.2., which will be released soon. In the Workspace format dialog | General tab, there will be a new option ‘Display Line Names’.
So, please check out the next Beta then. Thanks.
