Global or Project Parameters with formula and combine functionally similar to families

I have yet to find a need for global parameters. It would be useful if you could use other type parameters in formulas. For example Door: Width + Global Shim could be used to define the rough opening width of doors.

I think they need to be more widely available in components. Every time I think "hey, a global parameter would be useful here" the option is greyed out.

I've tried to use global parameters for a few things. They've worked pretty good for-

  • Materials such as window/door frames
  • heights, thicknesses and depths related to joinery 

They seem to break for (although I should revisit to test) - 

  • global window head or sill heights
  • typical floor offset heights for strucural beams or wall heights etc.
