I've created a composite comprising 10mm plasterboard and 90mm insulation which I want to use for both wall and ceiling to create ceiling bulkheads. How do I get these materials to join properly in cross-sections? I've create priorities 6 and 2 for plasterboard and insulations respectively.
That is disappointing. This is despite the fact that composites have been created to be used as 'slabs' and 'walls' - but they still won't join. Should this be a wishlist item?
