OK admittedly I went into a cold sweat!!
Aaagggggh what have they (the Factory) done with Visibility Graphics. I can’t switch the Surface Pattern Off (for Walls, Floors, and Roofs). It’s not there any more!!!!....................... Oh OK there it is (blush). Nice Subtle change.
So Projection and Cut have got an upgrade, with a more descriptive layout to easily override Line Styles and Patterns. To switch the Surface pattern off, select the override and toggle the visible switch in the dialogue box. Remember this is also per view or view specific.
That new Transparent addition is also banging man!! One simple click and I can now see inside without having to make all these transparent materials.
