Core Only Roof Cover Fill

Related to the above thread, roof cover fills also disappear when set to anything OTHER than Entire Model...

Feel like there were more wishes, some from over a decade ago, regarding tool consistancy on the Wishlist but I can only find a more recent one about Storey Display Settings....

How exactly would this work?

1. Would the same Cover Fill be displayed regardless of which skin of the Roof shows its top surface? E.g., if you specified "Roof" as Cover Fill, would it still display this "Roof" Cover Fill even when only the structural concrete skin of the Composite is displayed?

2. Or, would you have to specify a Cover Fill for each skin? (kind of complicates things)

3. Or, let us say, the Cover Fill would show in the case of these other Partial Structure Display options only, if Cover Fill is set to "User Fill from Surface"?

It can get kind of complicated when you start to think about the specifics.

It was more about consistency between tools currently. Slabs retain their cover fill when not set to Entire Model, so if you have "sloped slabs" and are using cover fills, you cannot really use the Partial Structure Display. Might possibly be able to GO the cover fill back onto the roof, but I have yet to try that...

Ideally it would match the cover fill of the partial structure, unless overridden, it which case it should not change.

I see. So, your wish is basically that the Roof tool's Cover Fill in relation to Partial Structure Display settings work the same way as the Slab tool's Cover Fill.
