While I am not a big fan of LOD's, the fact that you cannot use the flexible command with them I am not understanding why. In the assembly I have, I need sub-assemblies within the assembly that are currently within the walls of my assembly suppressed to work on the inner components. Part of that is making them suppressed to make the large assembly easier to work with.
Now I have to un-suppress them and change the visibility of the walls in order to work inside. Why? Please make this an option in future versions.
