has the ability to sort the parameters with the Ascending or Descending
buttons. Once the parameters are sorted, you can move each parameter
up or down within each group. This means important parameters can be
pushed to the top of a group, even though you may have sorted them
alphabetically.

The current version of Revit does not allow users to customize any of these

at the same time in the project. A good example for that is the Power unit of
measurement; it can be watts, BTU per second, horsepower, and a few more
choices. But in a real project, chances are you will want to use horsepower
for motors, watts or volt-amperes for electricity distribution, and maybe
kilowatts for the entire building or major blocks of the building. In reality,
you can't do that with Revit.
If you create a family that uses different units for certain parameters, the
family units will be changed after it is loaded into the project. This is a
significant roadblock for achieving true BIM because there are industry
standards for the units (W, VA, KW, and so forth) that need to be used
