See below the definition for the typical double cavity wall. Only layers outside the core can wrap. Only layers inside the core can be structural (previously at least one layer needed to be in the core – now no more). Importantly, the priority has now been removed from the function. The dimension tool can still only differentiate between wall face, core face and center of wall. We would have loved to be able to dimension to the face of the brick layer, and perhaps this is an idea for the future. Let the dimension latch onto the first layer of a certain priority?
