Revit 2017 moved the Space Naming Utility (SNU) into the formal tool set and named it the Space Naming tool. This new version of the tool is disabled if the Mechanical analysis tools is disabled.
An electrical engineer/designer has no need to see the mechanical analysis tools and may disable them. They will have the electrical analysis tools enabled. They will need to work with the space names. But the tool is disabled.

Please add an OR condition to the enabling of the tool to be enabled when ANY of the MEP analysis tools are enabled and not just the mechanical set.
Plumbing/piping folks are going to want the same thing.
