Roof composite structures

ArchiCad needs to treat roof surfaces like walls. There should be a way to construct a roof composite, such as built up roof over insulation over concrete over metal deck.

This would make sections a lot easier to draw!

? I've lost you? What are you saying exactly?
There are composites that you could apply too roofs.

Composites can be applied to walls, roofs and slabs. They're not exactly perfect, but it's a start.

Have you discovered that you can make a composite from what-ever fill patterns you wish? Once you do this you can apply your composite construction to a wall, a slab or a roof. There are no rules here, you are free to create what-ever you need.

For instance in the case of a flat roof (using the slab tool), it makes sense to create a composite of the sheathing, deck, insulation etc. just as it does with a wall or a slab. In the case of pitched, tiled roof construction though, I prefer to model the components separately (unless it's just for scheme design) - this results in accurate sections.

Hope this helps.

Strictly speaking, composites can only use fills that belong to the Cut Fills category.

Agreed. That's also what I meant about not being perfect. Usually the structure outside the wall is different to the structure inside the wall. Add to that the fascia/soffit system and composites start to fall down rather quickly.
