https://community.graphisoft.com/t5/Modeling/How-to-set-a-multi-plane-roof-with-flat-ceiling/m-p/216931#M117849 Thanks. I've realised that it is not possible to make a roof like this which is a bit strange as it is very common to build roofs like those in larger buildings with a straight joist and adding up with insulation to create the slope. I see a mesh as a better option in that case as you get one element with clean sections.

Use the Mesh Tool<BR /> 2. Add a slab for the flat ceiling, then SEO the Slab from the Roof<BR /> <BR /> If you want both to be flat, then use the Slab Tool.<BR /> <BR /> David Thu, 12 Dec 2013 13:41:16 GMT https://community.graphisoft.com/t5/Modeling/How-to-set-a-multi-plane-roof-with-flat-ceiling/m-p/216930#M117848 David Maudlin 2013-12-12T13:41:16Z https://community.graphisoft.com/t5/Modeling/How-to-set-a-multi-plane-roof-with-flat-ceiling/m-p/216931#M117849 Thanks.

Think of them in terms of what they do and how they work then use the most appropriate tool to your conditions. In this case, the mesh tool would be the best choice, although I would certainly consider using multiple elements, such as a slab or roof for the decking and mesh for insulation above, to more closely relate to how the roof would be constructed in reality.
