Am I the last person on earth to realize that you can have as many "whole house" models in XL as you want and they can be any combination of models you want? Finally! An easy way in XL to group all my snowflakes or group all my icicles or group all my windows or group my snowflakes and my icicles or .... In the preview tab, just uncheck "part of my display" from every model you don't want in the group, then click "Build Whole House Model" and it creates your grouping (change the name to the group name you want). You can do as many groupings, subgroupings, levels as you want (like Groups in Vixen 3 or Layers in LSP). How did I miss this when Whole House Model came out last year?
