Hi Andrew, when using the tool ‘create a slab’ :slab-tool: its seems I only got one choice of using material / surface for the floor at a time. The house that we’re doing are tiled in the living roomS & bathroom but carpeted in the bedrooms. So everything are just one type of flooring at the moment. Can we make it multiple not doing manually? I will send the model today for you to check. Everything that I thought not covered by this tools are created manually through skp (e.g. beams, chimney flue, joist, bearers etc.). Im still learning and familiarising with this but this is a great tool.
