Re: Guide To Creating A Flat Roof With Cut Outs For Skylights
Just an update if anyone tries a similar design in future - ie one that is essentially a house with a single floor level but multiple ceiling and roof heights.

What I was trying to do here was to deploy Sweethome 'levels' having a single ground level for the whole building and then have raised levels at different heights to be used as the basis for flat roofs at different heights ( although the roofs were actually floors as far as Sweethome was concerned ).

This all worked fine to a degree.

However each roof "slab" will get the same colour on the underside as on the top face so a dark grey roof will deliver a dark grey ceiling unless the Sweethome "show ceiling" option is used since that will "cover-up" the underside of the roof with a different texture or colour.

I have since discovered that for a given construction on one level it is only possible to have one unique ceiling height whereas I would need three different ceiling heights to cover up my grey roof when seen from below*

I can still achieve everything I currently want simply by prioritising the Sweethome ceiling for the one room where I use a texture (wood slat ceiling) currently - the limitation being that any other ceilings in other areas that also require this texture must be at the same height as the first, other rooms will have the "show ceiling" option false so that the roof slab shows as ceiling.

I will then default the three roofs to white ( the preferred ceiling colour ) and simply change the roof colours back to dark grey for any aerial video or photos - its not a big deal and will take only a few seconds.

I will still require the skylight White liners if I want the skylights to look realistic from above if I have reverted the roofs to dark grey.



Footnote: *I could possibly split my ground level building into several levels all at zero height but I think the pragmatic approach suggested above is easier.
