How do you not show room separation lines

[Bluefairy]

I seem to see room separation lines in my 3d views and some of my plan views where I dont what it to show. In order for them to not show do I have to click on the room separation lines and hide category? Is there not a setting in the visibility chart where I can turn off ?

In visibility graphics you can turn it off.

Go to model categories - lines - <Room Seperation> untick the box.

Or for quickness, select it and type 'VH'. Both methods work.
