Selecting a layer from multiple structures at the same time
You can easily modify similar layers from multiple structures at the same time. Previously, this was possible from the model tree. Now, you can do the same thing much faster. Select the floors, roofs, or ceilings whose layers you want to modify, then select "Layers and Visibility" from the context-sensitive menu. You can then choose which layers will be selected for editing, and which layers and parts of a layer will be visible.
