Not all slices shown in roof.

Hi.

I have some roof build-up. But for some reason not all layers of the roof build up is seen in roof calculation section view or in D-Cam section view. All layers 0,+1,+2,+3 etc. are shown, but none below layer 0. In the definition of the roof properties I have set all layers to show a panel of the layer.

What can be wrong, what can I try to look at, to fix it?

Yes? How to solve that?

Hi.

Yes, it helped to say that the slices 0 and inwards, are core slices. I just don't think I normally do that and normally it works (I think). But anyway it doesn't matter that more than the slice 0 is said to be core slice - it's just a practical definition.
