HumbleChief 481 Posted November 8, 2016 Just heard back from tech support regarding the double slabs being built on the plan attached in the thread below and it turns out I had defined a wall as a 29" thick wall that Chief could not resolve. They recommended 2 walls instead and I am not sure how large a wall can be spec'd before Chief doesn't play nice but in case someone else runs into a similar problem look for a thick wall and either delete or create using smaller walls. https://chieftalk.chiefarchitect.com/index.php?/topic/11638-disappearing-flooring/ Share this post Link to post Share on other sites
